To calculate our protective stop, we would take This would give us The keywords PointValue and PriceScale reflect the properties of the stock or commodity that you are currently testing. The keyword PointValue is the value per share of one increment of the PriceScale.

The keyword PriceScale is the quoted scaling factor of the instrument. If you have two decimal places in the price, then your PriceScale would be If you have four decimal places in the price, then your PriceScale would be 10, To figure out how a certain market is quoted hundredths, thousandths, etc. At the same time, we have also told TradeStation to cover a short position at either a protective stop or profit target limit.

Sounds great, right? Without adding the contingency of being in a long or short position, we have put the cart in front of the horse. So in our particular system the following will not work properly: BuyToCover "shortLoss" next bar at shortProtStop on a stop; BuyToCover "shortProfit" next bar at shortProfitStop on a limit; This is a logical error, and it is the hardest and most difficult to correct.

The compiler informs us of syntax errors and, in most cases, these types of errors are simple typos. Contingent orders must use some form of decision and, therefore, must be programmed with a program control structure. EasyLanguage usually automatically handles this necessity for the trader. A good example of looping can be found in the simple moving average calculation. In EasyLanguage, you can get the current moving average of a value by calling the Average function.

EasyLanguage accomplishes iterative processing looping through two different iterative statements: the for loop and the while loop. For Loop Use the for loop when you know exactly how many repetitions are to be processed. In the case of the moving average calculation, and most other calculations, we know exactly how many bars we will use. Previously, we calcu- Program Control Structures 49 lated a ten-bar moving average of the closing prices by calling the Average function. We have incorporated that ability into our for loop. The historical closing information can be extracted by indexing the keyword Close with our counter variable the name of this variable can be anything that is of numeric data type and can be used like any other variable.

Since the counter is less than or equal to nine it passes the test , the block of code immediately following the for statement is executed. When the program reaches the end of the block of code that is encapsulated by the for statement, it loops back up to the beginning of the for statement. EasyLanguage adds 1 to our counter now counter equals 1 and compares it to the end value.

This is similar in action to an if-then statement. Conditional branching is built-in to the for loop. Since we are still less than or equal to nine, we again execute the block of code that immediately follows the for statement. On the last go around, mySum was set to Close[0]. Do you see where we are going with this? In programming lingo, mySum is known as an accumulator.

The looping mechanism uses this variable to sum up the closing prices for the past ten days. The loop terminates after the counter reaches ten. You may think it would terminate when the counter 50 Building Winning Trading Systems with TradeStation reaches nine, but the for-loop processes from the starting number through the end number. When the counter reaches nine, it is still less than or equal to the end value and, therefore, processes the loop once again.

The next time through the loop, the counter is incremented to ten and then fails the test. Upon failure, control passes to the next line immediately following the for loop block. After this statement is processed, we then have the average of the closing prices for the past ten days. In EasyLanguage, you can have for loops that loop from lower numbers to higher numbers or vice versa.

If you loop from a higher number to a lower number, you must use the keyword downto or the program will not loop properly. While Loop The for loop works great when we know the number of repetitions that we want to process.

Again EasyLanguage comes to the rescue with the while loop. The while loop continues to loop while a certain logical condition remains true. Calendar Date EasyLanguage Representation Program Control Structures 51 By increasing the counter by 1 each time through the loop, we are actually going back in history. As we loop backward, we compare the highs and lows of the bars with the myHigh and myLow variables. Each time we find a higher high or lower low, we store those prices in our variables for later use.

The while loop is not terminated until we go back in time to the date of We were able to loop without knowing the exact number of repetitions that needed to be processed. Remember, the programmer makes the computer intelligent by setting up the decision process and the consequences of the decision. Decision-making is programmed through the use of if-then and if-then-else statements. These statements control which instructions are executed and which are not.

The for loop and while loop statements are two program control structures that provide us with one of the great benefits of computers: the ability to do repetitive tasks quickly. Understanding how computer programs make decisions is vital in our goals of accurately programming our analysis techniques. Without this power, TradeStation would not be any different than any of the other real-time charting software packages.

Each of these techniques are discussed, and sample code is given so that you can use it as a template for your own research. We have covered the basic essentials of programming from the first three chapters and now will use this knowledge to put our trading ideas into action. If you have used charting software before, you probably know what some of the most popular indicators are.

Indicators are the lines graphs that are either plotted on top of bar charts or in subgraphs above or below the bar chart. These lines are used to help understand and, in some cases, to forecast market action. Indicators are the plotted output of a formula applied to the price data. The most famous indicator of all is the moving average of closing prices. The graph of the moving average is a continuous line that can be plotted on the actual bar chart data. Not all indicators can be plotted on the underlying bar chart due to the difference in their scaling properties. The scale of the output of a moving average calculation is the same as the data that was used for the input.

Since the scale of the input and output of this indicator is the same, it 52 TradeStation Analysis Techniques 53 can be plotted on the same one as the price data. The outputs of some indicators, such as the relative strength index RSI, by Welles Wilder , have a different scale than price data and should be plotted in a subgraph. However, with TradeStation you can graph these types of indicators on the bar chart if you like. Keep in mind that the graphs have different scales. The output of most indicator functions does not create smooth-looking, continuous graphs. They generate a data point for each bar of data and then TradeStation connects these lines together in a connect-the-dots fashion.

Create a daily bar chart of days for Yahoo! A dialog box like the one in Figure 4. Scroll through the list of indicators and select Mov Avg 1 Line. Make sure the Prompt for Format box is checked and then click OK. Since we checked the Prompt for Format box, you will be presented with another dialog box that should be like the one in Figure 4. This dialog box allows the user to change the format of the Mov Avg 1 Line indicator. Here the width, color, and style of the line and the inputs if any of the indicator can be changed.

Click on the Scaling tab and you will have a choice of four different scaling types: Figure 4. Screen: Select this option to display only the range of values currently displayed on the screen without regard to the range of data loaded for the chart. Entire data series: Choose this option to display the entire range of values for all data loaded in the chart, no matter how far you scroll to the left or right of the current screen view. User-defined: Select this option to format the y-axis to your preferences. Enter the lowest value to use in the Minimum box and the highest value in the Maximum box.

Check the Same as symbol box and then click OK. You should have a chart window similar to Figure 4. You can scroll through the data and the indicator will change based on the data that is currently in your view. You may want to play with changing the format of this indicator or inserting more of the built-in indicators as practice.

Applying an indicator requires a few mouse clicks and pecks at the keyboard. Programming an indicator can be as simple if you understand the basic framework and the keywords or functions that are used in the development of this type of analysis technique. Make sure TradeStation is up and running and go under the File menu and select New. You may remember this dialog box from Chapter 1. The New Indicator dialog box will open and ask you to type in the name of the indicator and some notes about the indicator.

This dialog box will also ask you to make the analysis technique available to a chart analysis.

We always check this box. Finally, you can choose what type of template from which to use when building your indicator. Select none and then click OK. Once you become an EasyLanguage pro, you will probably want to use a programming template. These templates provide some code to get you Figure 4. TradeStation has initially created an indicator based on our input from the previous dialog boxes. Type the following code exactly as you see here: Inputs: myPrice close ,myLength 9 ; Vars: counter 0 ,sum 0. Again, if you get any error, double-check your code for any typos.

Click OK in the associated dialog boxes until you have the moving average line overlaying the price data. It should look similar to the chart in Figure 4. TradeStation Analysis Techniques 57 Figure 4. These two inputs allow the user the freedom to pick what data Open, High, Low, Close, or Volume and how many days to use in the calculation. We have designed this indicator to be about as flexible as possible. We could have programmed the indicator with only the myLength input and forced the user to always use a hard-coded programming designed to get a particular job done without regard to future flexibility price series.

Our indicator would not be universal, and you would have to have four different indicators for each price series. The previous programming allows MyMovAvgIndic to be universal. We can calculate the moving average of the Highs, Lows, Opens, or Closes of any market by simply changing our first input, myPrice.

In the discussion of indicator flexibility, we brought up the term series. Remember in Chapter 1 when we introduced data types? There were basically three different types: numeric, Boolean, and string. The numeric type can be 58 Building Winning Trading Systems with TradeStation divided into two different categories: simple and series. A variable of type numeric simple has only one value at a time. In the code of MyMovAvgIndic, the variable sum is of this type. A variable of type numeric series is one that has a list of different values. The keywords Open, High, Low, and Close are of this type.

We can index these variables and get different values e. In computer lingo, these variables are known as arrays.

An array is a list of items that have something in common. Like most other high-level programming languages, EasyLanguage allows you to define variables as arrays. The average trader seldom uses arrays beyond the built-in array variables, so we will temporarily put this discussion on hold. Just know that when we say a price series, we mean a list of the entire history of that particular price Open, High, Low, and Close.

We know the inputs and their functions and for loops Chapter 3 and how to calculate the moving average of prices. The line of code that makes this program an indicator is: Plot1 myAverage, "SimpAvg1" ; This statement tells TradeStation to plot the value of the variable myAverage in a chart window below the chart of the price data.

Once the indicator is plotted, we simply drag it from the subgraph onto the same graph as the price data and use the same scaling. You can see where price crosses the moving average line. To determine the exact date that a price bar crosses from above or below the moving average line, you must set the scale of the two graphs to be exactly the same.

The Plot1 keyword acts in similar fashion to a function call. We passed it a list of parameters and it did something for us. It can also return the value of the plot from the most recent bar that was executed. Plot1 is different than the functions that we have discussed in that you can pass it a different number of parameters.

In our example, we simply passed the value that we wanted to plot and the name of the indicator. This name shows up in the information window that pops up when you click on a bar in a chart. We could have passed more or less parameters to the Plot1 statement: Plot1 Value ; or Plot1 Value, "My Plot Name", Red, Default, 0 ; Plot1 can take up to five parameters: 1 the value to be plotted, 2 the name of the plot optional , 3 the color of the plot optional , 4 background color optional , and 5 the thickness of the line that represents the plot.

EasyLan- TradeStation Analysis Techniques 59 guage only requires the value to be plotted in the Plot1 statement; the other arguments are optional. Even though some of the arguments are optional, the order of the arguments is important. EasyLanguage expects the first argument to be the value to be plotted, and the second argument to be the name of the plot and so on. This order has to be clear. You would have to pass all of the arguments because the width argument is last in order. You would have to invoke the Plot1 statement by typing: Plot1 myValue,"myValueName",Default,Default,5 ; The keyword Default tells TradeStation to accept whatever default values exist for that particular argument.

In this case, they are the color of the plot and the background color. EasyLanguage is smart, but it is not a mind reader.

It knows which values are being used by their place in the argument list. Indicators are powerful tools in the analysis of data and the design of trading strategies. If you want to include an indicator in a strategy, you can quickly plot the indicator and visually evaluate its effectiveness. Unfortunately, as we explained in The Ultimate Trading Guide Hill, Pruitt, and Hill, John Wiley, , most canned included for free indicators are not effective by themselves. The PaintBar study will mark the entire bar, whereas the ShowMe study will usually place a mark above or below the bar.

These studies make it easy to visually interpret different market conditions; for example, you can paint bars one color when the market is overbought and another color when it is oversold. ShowMe studies are best used for criteria that result in a low frequency of occurrences. The less dots that are above or below a bar, the easier it is to visually interpret the market activity following the occurrence of the certain criteria. Pivot highs and pivot lows are best illustrated with a ShowMe study rather than a PaintBar study. We prefer to use ShowMe studies for pattern recognition and PaintBar studies for illustration of certain market modes.

The best way to learn to program these analysis techniques is to jump in and create them from scratch. With TradeStation running, go under the File menu and select New. The now familiar dialog box will come up. You will be presented with a blank, yet familiar EasyLanguage window. Type the following code in exactly. You will notice the further you get into this book, the less descriptive we become in our instructions.

We feel this promotes your ability to remember the processes necessary to use TradeStation. Once you have inserted MyPaintBar into the chart, you should be able to scroll through the chart and see the yellow and red daily bars. If you would like to see if our PaintBar study is accurate, go ahead and insert the RSI indicator with our same inputs. We should have red bars when the oscillator is in the overbought region and yellow bars when it is in the oversold region. The code for our PaintBar study is similar in structure to our moving average indicator that we programmed earlier.

If you hold the mouse button down and scroll across a bar that has been painted, you will get a RSI1 and RSI2 value in the bar information window. These values represent the high and the low prices of the bar. You can use any word you like. We painted our overbought bars red by telling TradeStation to use the color red in our PlotPaintBar statement. We wanted to paint TradeStation Analysis Techniques 61 bars two different colors based on market conditions, so we chose the colors ourselves. In our PaintBar study, we painted the entire bar from top to bottom.

Using the PlotPaintBar statement is quite easy. The hard part is creating the criteria necessary to determine when and when not to use the statement. When you typed the code for MyPaintBar, we used an ifthen construct to alter the flow of the program. We only painted a bar red when the RSI was above We only painted a bar yellow when the RSI was below We can quickly scan this chart and determine potential overbought and oversold market conditions.

We have programmed a complex pattern recognition PaintBar to illustrate this point. The coding for this PaintBar will draw on everything we have learned up to this point. We will program the first stage of the pattern and paint the bars that fall within our pattern recognition criteria. Type the following into your EasyLanguage document and verify it. You will probably want to delete the other analysis techniques before inserting this one. The code for MySequentialHunter may look daunting, but it is relatively simple.

We have four for TradeStation Analysis Techniques 63 loops. The first loop counts the consecutive days that the closing price is less than the closing price four days prior. If we have nine consecutive closes that meet our criteria, then the checkSum variable will be equal to nine. If checkSum is equal to nine, we then proceed to the next for loop. This loop calls the PlotPaintBar statement nine times our index variable goes from 0 to 8. The first time through the loop, the index is equal to zero. This may or may not paint the bar the way you want it to be. Just remember to paint the correct high and low price for the corresponding bar in the past.

Most analysis techniques are symmetric; a bullish analysis is usually just the opposite of a bearish analysis. Once you program the bullish analysis technique, you can quickly create the bearish analysis by simply copying, pasting, and editing the logic. Many times you can accomplish this by simply changing Highs to Lows, greater than to less than, positive numbers to negative, and so on.

Once you get a blank EasyLanguage document, type the following in exactly. In our ShowMe study, we mark the two bars that make up the Two-Day flip pattern. As we did in our PaintBar, we programmed our setup criteria by using if-then program control structures. We only mark the bars that pass our test. The Two-Day flip can indicate an end to a bullish or bearish trend. See the symmetry? This is a general description of the pattern.

Again, the bearish version is just the opposite. This exact mechanical description is necessary for successful translation into EasyLanguage. The Plot1 statement that we use in our ShowMe study is the exact same statement that we used in our Indicator. Instead of creating a continuous line that represents an output of a formula, we are using the statement to demark a bar that meets a certain criterion.

Once we encounter a day that does not pass our criteria, the drawing stops. Hence, you have dots instead of a continuous line. Each plot statement can represent a different value; Plot1 could be a moving average value, whereas Plot2 could be a Bollinger Band. The key to an accurate PaintBar or ShowMe study is found in the programming of the criteria.

One of the most important concepts to efficient programming is the idea of reusable code. Many of the indicators and strategies that you will develop will mostly consist of function calls. You can think of the functions that make up the library as small building blocks and yourself as a mason.

It is your job to build your analysis techniques out of these blocks. Of course, there will be times when a mason must customize a block to fit a particular project. By tweaking, we mean changing a portion of the code that makes up the function. If you ever do this, always remember to save your modified function under a different name than the 66 Building Winning Trading Systems with TradeStation original.

You want to keep the built-in library as pristine as possible. Many times you will borrow or purchase code from other TradeStation users, and in most cases this code will presume that the built-in library is the same as the one from the computer where it was created.

As a programmer, you are not limited to using functions or simply editing existing ones. You can create these building blocks from scratch. The more you program, the more intricate your programming becomes. Elaborate programs require elaborate building blocks.

In the early stages of learning how to program analysis techniques, the built-in library is more than sufficient. As you progress, you will soon discover that the library is too limiting and must be expanded. You expand the library by creating functions. The first is when you discover that you are repetitiously typing the same code over and over again. The second is when you discover the Holy Grail and you would like to pass this information on to other users for free. For free? Go up under the File menu and go to New. When the dialog box opens, select function. You will notice that we must inform TradeStation of the type of data that our function will return.

Most of the time, a function will either return a numeric or Boolean value. A function can also return a string value a letter or a string of letters , but we have never encountered the need for this. Click on Numeric simple and hit OK. A lower value denotes higher market indecisiveness choppiness , whereas a higher value denotes a trending market. The only input is the number of bars that we look back.

Trading Systems and Methods + Website 5th edition Wiley Trading

We calculated the denom denominator by using the Highest and Lowest functions. We calculated the num numerator by using AbsValue returns the absolute value of a number functions. The only confusing snippet of code in this function is probably: Close[periodLength-1] — Close You may be asking why we subtracted 1 from the periodLength. This is a great question. Since we want our index to flow between 0 and positive , we remove the negative sign of a down move in the market.

We are only interested in absolute distances.

Becoming a good EasyLanguage programmer does not require an indepth knowledge of the intricacies of all of the built-in functions. It does, however, require knowledge of how to put all of the pieces together. Maybe we really should call ourselves masons instead of programmers. The function that we just typed in and verified can be used to determine the current choppiness of a market. Later on when we begin to develop successful trading strategies, we will use this function as a building block. The ChoppyMarketIndex function determines market choppiness by dividing the change in market price for the past 30 days by the total distance the market has traveled during that time period.

If the net change in market price is small and the market has demonstrated wild swings, the ChoppyMarketIndex function will return a small number. In the following description of our function, we assume the periodLength is equal to The variable num is assigned this value. We then determine the total distance the market has traveled by subtracting the lowest low for the past 30 days from the highest high of the past 30 days. The variable denom is assigned this value.

The ChoppyMarketIndex is then assigned the value of num divided by denom multiplied by Since the change in market price for the past 30 days will always be equal to or smaller than the total distance the market has moved over the same time period, our function will always return a number between 0 and You will notice that we have made the function flexible.

We used an input as the period length. By doing this, we have allowed the user of this function the ability to change the number of days that is used in the calculation. If you are developing a short-term strategy, then you would probably pass the 68 Building Winning Trading Systems with TradeStation function a short period length and vice versa. Once you have finished your calculations for a function, you must assign a value to the name of the function.

In this case, we assigned our final calculation to ChoppyMarketIndex, the name of our function. If you forget to do this, the function will not return an accurate value. This function is actually useful and will be the basis for one of the strategies that we develop in Chapter 6. Did you notice that in the Inputs statement of this function we used NumericSimple inside the parentheses of our Input variable, periodLength?

Again, this is a wonderful question and since functions are the backbone of TradeStation, it should be answered in great detail. Functions are in some ways similar to other Analysis Techniques, but overall they are quite different. Think of functions as separate subprograms. These subprograms are designed to calculate and change the value of some variable. Indicators, ShowMe, and PaintBars are designed to graphically represent an idea or a mathematical expression. When we create a function, TradeStation needs to know ahead of time what type of variable the function would return.

TradeStation also needs to know the type of information that is being passed to the function, which is why we used the keyword NumericSimple in the Input statement. It is the doorway that data and information passes. In computer lingo, it is also known as the formal parameter or argument list. Like the function itself, a parameter can be of subtype simple, series or reference. Simple parameters are constant values that are set in the trading strategy or analysis technique that calls the function. Our periodLength parameter is of this type.

Simple parameters require less memory and improve overall execution speed. They retain their values within the function and cannot be modified within the body of the function. Like simple parameters, series parameters are constant values that are set in the trading strategy or analysis technique that calls the function. However, when the function refers to previous values of the input variable you use as the parameter, then this parameter must be defined as a series parameter. Current and historical values of the input variable are accessible from within the body of the function.

To make the function as flexible as possible, you want to give the user or caller of the function the ability to choose which data series is used. With this in mind, you would program the function to accept NumericSeries type data. Take a look at the following code as it might help clear up some of this confusion. This prepares TradeStation, ahead of time, to accept the history of the variable that is passed to the function.

In computer lingo, this preparation is known as function prototyping. So, to summarize, a simple parameter is just one value, whereas a series parameter is a list of values. Like simple parameters, series parameters cannot be changed within the body of the function. Parameters can be passed to a function by value or by reference. When the parameter passes information by value, as is the case with simple and series type parameters, the function creates a copy of the information passed into it, and whatever is done with the parameter in the function does not affect the value of the parameter within the trading strategy or analysis technique that called the function.

When information is passed by reference, the function uses the original information from the trading strategy or analysis technique that called the function, and any calculations that are performed on the parameter are reflected in the value of the parameter within the analysis technique that called the function as well as within the function.

Why on Earth would you want to do this? Remember how we are always comparing EasyLanguage to modern-day, high-level programming languages? Most programming languages have two types of subprograms: functions and subroutines. Functions are used when a calculation returns only one value. Subroutines are used when more than one value is calculated or a chore is needed to do more than just simply return a value of a calculation. The programming that went into the creation of TradeStation uses functions and subroutines. When you click on a menu, a subroutine is called to handle the actual drawing of the menu list and another subroutine is called to handle whatever command you choose from the menu.

These subroutines do more than just return single values. Since we are not programming a graphical user interface, we will simply use the reference type and functions to return multiple values. In all honesty, you probably will only use reference-type parameters on rare occasions. The following function demonstrates the proper use of these types of parameters. All functions must return a value. In the case of ZoneBands, the statement that assigns a value to the function name is only there for syntactical correctness.

This function in fact returns four different and significant values. Once they are changed within the body of the function, they are forever changed. We were able to calculate four variables from one function call. The following snippet of code illustrates how to use this type of function call. We assigned a temporary variable the value that is returned from the call to ZoneBands. Indicators are used more or less as tools, whereas strategies are used as the mechanisms to generate exact buy and sell signals.

Strategies are the vehicles that most third-party developers use to sell their ideas. You may not believe us when we say that a good portion of TradeStation users only use their software as an interface for these strategies for hire. TradeStation can be used as a research tool or as a tool for information dissemination. As you have seen from the previous chapters, strategies are programmed in similar fashion to other analysis techniques. The one thing that separates strategies from other analysis techniques is they issue orders.

As we have discussed, TradeStation can place three types of orders: TradeStation Analysis Techniques 71 market, limit, and stop. Market orders can be placed this bar on close or next bar at market. Strategies can place multiple orders for any single bar. TradeStation has two rules that determine which orders get filled: 1. Orders on Close and Next Bar at Market 2.

Stop and Limit Orders Orders placed to be filled this bar on close have the highest priority. Once all of these orders have been filled, the next bar at market orders are evaluated. If there is more than one order with the same execution method, the order that was placed first in the strategy takes priority and is filled first.

Once all market orders are evaluated, the Trading Strategy Testing Engine analyzes stop and limit orders. If there are multiple stop or limit orders, then TradeStation gives a higher priority to the order that is closest to the market closest to the current price. This is done in order to simulate how stop and limit orders are actually filled. If a symbol is trading at , and there are two limit orders to buy—one at and one at —as the market drops, the order to buy at would be filled first, and the order to buy at would be filled second. Therefore, TradeStation fills these orders in that way, producing results that are as realistic as possible.

If stop orders are used and you have two orders to buy at and and the current price is and rising, then the stop is filled first and then the By generating exact entry and exit orders, strategies can be back tested over several years of historical data to determine effectiveness. Chapter 5 is dedicated to the analysis of strategy performance and optimization. The rest of this chapter will illustrate how to create trading strategies utilizing built-in EasyLanguage functions. You may have noticed the words crosses above and crosses below in these functions.

Building Winning Algorithmic Trading Systems: A Trader s Journey From…

The book gives a good overview and many warnings that one should heed. However, be warned that this author is extremely misleading in his performance. If you read his blog, etc he makes it sound like he makes lots of money trading; using this to push his classes and touting how honest he is. Well, he used to have some systems on stryker and they have all blown up in a spectacular fashion. The author is very likely making all his money from selling books and classes, not from trading.

October 10, - Published on Amazon. This book is about the validation of trading systems, not about building. Therefore, almost no ideas about how to come up with a trading system are presented. Half the book is about going through an example case of how to optimize and validate two crude and unmotivated trading systems. The backtests and forward tests of those examples look good after optimization. Davey then proceeds to show 15 weeks of "live" trading which show absolutely zero performance.

Assuming that this lies within the range of normal variability, he points to his website at the end of the book, where he promises to continue tracking even trading the system. On his website one finds out that he kept tracking the two systems for about 2 additional years before he threw the towel. Both systems combined and separate never showed any performance.

Classic case of fitting the noise. The procedures described in the book: validation and optimization, should exactly avoid such a disaster. But they don't. So even if you give this book some slack and say: okay it's only about validating and not about building trading systems, it doesn't deliver. So ultimately this book at least serves a lesson: building winning algorithmic trading systems is hard and fitting the noise is easy, even if you run validations and do forward testing.

November 3, - Published on Amazon. I have to give this 3 stars because it is badly mistitled. The correct title of this book should be "Testing Algorithmic Trading Systems" because that is exactly what the book is all about. There is virtually nothing in the book about BUILDING algorithmic trading systems winning or otherwise , or providing ideas on how to build a WINNING strategy such as a discussion of successful approaches to trade entries, exits, managing trades in the areas of stop losses, profit stops, trailing stops, etc.

If you are interested in discussions of how to actually build winning trading systems this is not the book for you as it is devoid of any such information. But if you already have strategy ideas and want to learn more about how to test them thoroughly then that is what this book is all about, and it is very easy to read and follow. I'd give it 4 stars if it was titled correctly. August 6, - Published on Amazon.
