Part 13: Meta Trader 4 Show – Strategy Tester (+Video)

I’m sure this must have happened to you at some point. You’ve downloaded a Strategy for Binary Options into Meta Trader 4 and everything looked great. If you’ve gone back a couple of days or even weeks in the graph, the strategy really seems to be profitable!

So, you start trading on a demo account or even on a real account.

The strategy is actually awful and the first few trades are already in a loss. Why is it?

The strategy repaints. That’s the main reason. But how to defend yourself against it?

The strategy may seem profitable, but it is not!

I personally have come across this exact problem as well. The last time, a few days ago when I was developing my new strategy. Everything looked great until it came to actual testing with Strategy tester. The strategy should have a 90% success rate, see the image below.

The strategy should have a 90% success rate. Let’s try it!

As the picture shows clearly, there should be a high success rate. Even if we look further back in history, all you see are mainly the successful signals. But you must not let yourself be tempted, everything should be tested using Strategy Tester, a built-in feature in MT4, before you use it to trade real money. This feature will be projecting real graph movements, so you can see exactly how the strategy behaves before redrawing.

How to use it? At the top of the MT4 window just click on the button: View > Strategy Tester or press Ctrl+R. A window opens at the bottom of the screen.

An opened Strategy Tester window after pressingCtrl+R.

How to use the Strategy Tester

Strategy tester is used very easily. First, we need to set up 3 things:

  • A: Symbol. Currency pair or commodity on which we want to perform the test.
  • B: The timeframe when we want to perform the test (can not be changed later)
  • C: The date we want to choose for testing. We can test the strategy on, for example, real data from the previous month.
  • Start

After clicking on the Start button, a new chart (Visual) opens, where the testing takes place. Now, a real progress of past chart begins to project, so we can see how exactly did the strategy behave. Quickly select a template with your indicators and you start testing!

Binary Options Strategy Tester

When it comes to using an indicator for binary options trading, it is always recommended to analyse it properly. And why not, when it can have all the chances to fail? For example, when you buy something essential and costly you will try to evaluate it first before you buy, right? Then why not do the same in the case of the indicators, after all, you will be risking real money?

Does Strategy Tester Really Work?

One of the best ways to test an indicator or a strategy is by paper trading in which you need to scroll back the chart while seeking signals in accordance with the indicator strategy you are willing to evaluate. But then this type of method is sometimes subjective as you get to see the entire chart the possibility of getting influenced is more. This article takes to explaining the way of evaluating strategies like you are trading in real time.

Using the Strategy Tester

Available in Meta Trader 4 platform, to use the Tester you require to open a chart of the currency pair to want to conduct the test on. Once you have done that you will need to attach a default Expert Advisors to it that is again available on the MT4 platform. Usually, known as MACD sample, these default EAs need to be dragged and dropped on the chart I. With that a small window is likely to open, which will let you select the settings for the Expert Advisor. However, it is not an important job, so you can skip that.

Next, what you should do is click on the ‘Strategy Tester’ button that should be near the navigator. But then, there are some platforms that do not have it. In that case, you just need to press F6 and the window will appear. And then you will get to see many settings that you should adjust. You might get the following tabs;

  • EA: As for this part that is the Expert Advisor you have sent needs no modifications.
  • Symbols: You can choose a symbol to select your desirable currency pair. But if you have already opened a chart of your likeable pair, then you need not do anything.
  • Method: You should use ‘Every tick’ setting as then it shows the most accurate market conditions. It’s however slower than other methods.
  • Use Date: For this, you should select the period that you wish to set.

Now, while you move to the middle column, you will get to see three things;

  1. Period: Here, you must select the time frame (for binary trading it is recommended to use M1 or M5 or M15, depending on your trading strategy.)
  2. Spread: This, you can leave unchanged, since it’s not necessary for binary trading
  3. Optimization: This one must be left unchanged

Tabs of the opened strategy tester

When you move to the right column you don’t have to change much except clicking the ‘Start’ tab. Once you do that, a fresh chart will come up. Now, you will find the prices oscillating in a normal market condition. If you think that you have gone back in the time and so you have the control of the market in your hand, then that isn’t the case. But then, you have the leverage to adjust the speed of the movement as well as hit ‘pause’ in order to get better peanuts. Last but not the least; you will have to add indicators to it, provided you have one.

Analysing the Usability of the Strategy Tester

Although the entire process seems to be very complicating, you cannot deny the benefits attached. By using this you can get close to real market trading. It is therefore undoubtedly one of the finest methods to train yourself before investing in binary options trading. Here you can see what a test will show you.

How to build and test a Binary Options strategy with the MetaTrader 4 Strategy Tester

Table of Contents

1. Introduction

This article shows how to build a Binary Options strategy and test it in Strategy-Tester of Metatrader 4 with Binary-Options-Strategy-Tester utility. By default Strategy-Tester of Metatrader 4 can test Expert Advisors and Indicators against historical data, but it cannot handle Binary Options with expire times. As I need a possibility to test Binary Options strategies automated in Strategy-Tester of MetaTrader 4, the Binary-Options-Strategy-Tester was build as a utility to fit those needs.

The concept contains the following parts:

This is a step by step example how to build a Binary Options strategy stored in an Indicator (marked as red in image above) to communicate through Binary-Options-Strategy-Library (marked as green in image above) with the Binary-Options-Strategy-Tester (marked as blue in image above), to place virtual orders and count their results with backtests and forward tests.

Please keep in mind: Backtesting with historical data will never represent the real future, but it might give you an approximate value to get your strategy more stable.
The quality of your backtest will depends on your historical data. Therefore it is strongly recommended to use a set of hight quality data!

2. Installation

Download and purchase Binary-Options-Strategy-Tester utility from marketplace:
Test-Framework to test Binary Options strategies in Strategy-Tester of MetaTrader 4.

Why a purchased version of Binary-Options-Strategy-Tester utility is needed?
A Binary-Options strategy has to call a function of the Binary-Options-Strategy-Tester (via Binary-Options-Strategy-Library) to place the virtual trades. Related to the license concept of MQL4 this only works if the product has a working license. Therefore you have to purchase the product to test Binary Options strategies or this example.

Download free BinaryOptionsStrategyLibrary.mqh and place it in into folder \Include ([path to your MetaTrader 4]\MQL4\Include):
The free library will provide several functions to build your Binary Options strategy easily and to communicate with the Binary-Options-Strategy-Tester. See Binary-Options-Strategy-Library for more details of the library.

Download free KVO.mq4 indicator and place it (and the compiled KVO.ex4 file) into folder \Indicators\Downloads ([path to your MetaTrader 4]\MQL4\Indicators\Downloads):
The KVO indicator is used as an example to show the access of external indicators and there ex4 files in section “3.2.6 Use of external Indicators (ex4 files)”. See https://www.mql5.com/en/code/8677 for more details of the indicator.

Now you can go further with section “3. Binary options strategy example” and build the example code by yourself or just download the code of this example below.

Optional download BinaryOptionsStrategyExample.mq4 and place it (and the compiled BinaryOptionsStrategyExample.ex4 file) into folder \Indicators ([path to your MetaTrader 4]\MQL4\Indicators):
Download the code of this Binary Options strategy example to let it run without building it by yourself.

To compile the needed .ex4 files open the .mq4 files (KVO.mq4 and BinaryOptionsStrategyExample.mq4 – NOT Binary-Options-Strategy-Library.mqh) in MetaQuotes Language Editor and click on button “Compile” or just restart your MetaTrader 4 after these files are stored in the described folders and MetaTrader 4 will do this automatically for you.

3. Binary Options strategy example

The following steps will guide you throgh an example how to build an example Binary Options strategy stored in an Indicator to communicate with Binary-Options-Strategy-Tester. You can build it by yourself or just download the code of the BinaryOptionsStrategyExample.mq4.

Please note: This strategy is not a profitable Binary Options strategy! It is just an example how to build a strategy in an indicator to communicate with the Binary-Options-Strategy-Tester utility. Of course you have to build a profitable strategy by yourself. But as you will see, this utility will help you to test and improve your Binary Options strategy.

3.1 Define Binary Options strategy

First of all we have to define the strategy and the changable values (input parameters). MQL4 documentation shows all technical indicators, which can be adressed over the iCustom interface: https://docs.mql4.com/indicators.

Let us say we like to create a simple Moving Average cross strategy with one “fast” and one “slow” Moving Average to trade on next candle after they have crossed each other. Documentation tells, how we can get the value of a single Moving Average: https://docs.mql4.com/indicators/ima.

Let us further say, we like to choose values for “MA averaging period” (fast and slow) and for “applied price” as well as for the “averaging method”. Other values (like symbol, timeframe and shift) depends on the testcase (e.g. the symbol the tester runs on) and should be set automatically. Therefore we basically need the following variables for a Moving Average:

As we need two Moving Averages to check their crosses, we need the following input parameters for the strategy example with some default values:

3.2 Create Binary Options strategy

You need to build an indicator which stores your Binary Options strategy to drag it on the chart where Binary-Options-Strategy-Tester is running on.

Open MetaQuotes Language Editor (in MetaTrader 4 click on “Tools” -> “MetaQuotes Language editor” or just press F4) and click on “New”:

The MQL Wizard will appear. Select “Custom Indicator” to create an empty indicator and click on “Next”:

Enter the name, copyright and link of the strategy as well as the input parameters with their types and default values (initial values) by clicking “Add”-Button and press “Next”:

On tab event handlers select checkbox “OnCalculate” as we need this event to check for our strategy on every tick. Press “Next”:

On tab drawing properties select checkbox “Indicator in seperate window” as we need a seperate window to print out the debug values. Press “Finish”:

The initial code of your indicator will appear:

const double &high[],
const double &low[],
const double &close[],
const long &tick_volume[],
const long &volume[],
const int &spread[])
<
//—

3.2.1 Input parameters

The initial input parameters are created with the MQL Wizard (see 3.2 Create Binary Options strategy) and we will enhance them with the following steps.

To avoid to have to enter int-values for applied price and averaging method of the Moving Averages for input parameters, the type for method_both and applied_price_both is changed from int to type of enumeration with a default value.

In addition comments for the input parameters are added to show the comments as labels instead of variable names:

//— input parameters
input int period_fast = 5 ; //Fast MA value
input int period_slow = 10 ; //Slow MA value
input ENUM_MA_METHOD method_both = MODE_SMA; //MA method
input ENUM_APPLIED_PRICE applied_price_both = PRICE_CLOSE; //MA applied price

With this modifications the input parameters provides a dropdown with the available values to select as well as “labels” for the input parameters:

3.2.2 Include Binary-Options-Strategy-Library

If you have downloaded and stored the library (see 2. Installation) into \Include folder ([path to your MetaTrader 4]\MQL4\Include), you are able to include the library like this:

//+——————————————————————+
//| BinaryOptionsStrategyExample.mq4 |
//| Copyright 2020, __martin__ |
//| https://www.mql5.com/en/users/__martin__ |
//+——————————————————————+
#property copyright “Copyright 2020, __martin__”
#property link “https://www.mql5.com/en/users/__martin__”
#property version “1.00”
#property strict
#property indicator_separate_window

Binary-Options-Strategy-Library will enhance the input parameters with two new parameters:

  • Place only one SELL or one BUY trade per candle
  • Check only at the beginning of a new candle for the strategy

3.2.3 Add CallStrategy()

Add a call to CallStrategy()-function in OnCalculate() of your strategy indicator to call the strategy on every new tick. CallStrategy() is provided by Binary-Options-Strategy-Library you have inlcuded like discribed above:

3.2.4 Implement CheckMyRules() and helper-function

In CheckMyRules()-function, which is called through the Binary-Options-Strategy-Library, the conditions for the strategy are implemented and trades are placed through PlaceTrade()-function of the library. Values of both Moving Averages are temporarilly stored in variables to compare them in if-conditions while the values of the Moving Averages are taken from the helper-function GetValuesForMA():

//— input parameters
input int period_fast = 5 ; //Fast MA value
input int period_slow = 10 ; //Slow MA value
input ENUM_MA_METHOD method_both = MODE_SMA; //MA method
input ENUM_APPLIED_PRICE applied_price_both = PRICE_CLOSE; //MA applied price

//+——————————————————————+
//| Place your Trading-Rules here – see example below. |
//| StrategyTester will call this function to place trades. |
//| DO NOT: |
//| – Rename function |
//| – Add function paramaters, e.g. CheckMyRules(int a) |
//| – Change function return type, e.g. int CheckMyRules() |
//+——————————————————————+
void CheckMyRules()
<

//Store MA values with shift=0 (current candle) -> current candle,
//call helper function GetValueForMA() to get the value – see helper-functions below
double emaSlow_Current = GetValueForMA(period_slow, 0 );
double emaFast_Current = GetValueForMA(period_fast, 0 );

//Store MA values with shift=1 (past candle) -> last candle,
//call helper function GetValueForMA() to get the value – see helper-functions below
double emaSlow_Past = GetValueForMA(period_slow, 1 );
double emaFast_Past = GetValueForMA(period_fast, 1 );

if (emaFast_Past > emaSlow_Past
&& emaFast_Current //Check if slow MA and fast MA crosses
<
PlaceTrade( OP_SELL ); //Place SELL-Trade for Strategy-Tester, function is located in BinaryOptionsStrategyFunctions.mqh
>

if (emaFast_Past
&& emaFast_Current > emaSlow_Past) //Check if slow MA and fast MA crosses
<
PlaceTrade( OP_BUY ); //Place BUY-Trade for Strategy-Tester, function is located in BinaryOptionsStrategyFunctions.mqh
>

3.2.5 Print out debug values

The function PrintDebugValue() privides a possibility to print out debug values while the tester is running. In the example below the values of the Moving Averages are printed out with their variable names as labels:

//— input parameters
input int period_fast = 5 ; //Fast MA value
input int period_slow = 10 ; //Slow MA value
input ENUM_MA_METHOD method_both = MODE_SMA; //MA method
input ENUM_APPLIED_PRICE applied_price_both = PRICE_CLOSE; //MA applied price

//+——————————————————————+
//| Place your Trading-Rules here – see example below. |
//| StrategyTester will call this function to place trades. |
//| DO NOT: |
//| – Rename function |
//| – Add function paramaters, e.g. CheckMyRules(int a) |
//| – Change function return type, e.g. int CheckMyRules() |
//+——————————————————————+
void CheckMyRules()
<

//Store MA values with shift=0 (current candle) -> current candle,
//call helper function GetValueForMA() to get the value – see helper-functions below
double emaSlow_Current = GetValueForMA(period_slow, 0 );
double emaFast_Current = GetValueForMA(period_fast, 0 );

//Store MA values with shift=1 (past candle) -> last candle,
//call helper function GetValueForMA() to get the value – see helper-functions below
double emaSlow_Past = GetValueForMA(period_slow, 1 );
double emaFast_Past = GetValueForMA(period_fast, 1 );

PrintDebugValue( “emaSlow_Current: ” ,( string )emaSlow_Current, 0 ); //Label and value in line 0
PrintDebugValue( “emaFast_Current: ” ,( string )emaFast_Current, 1 ); //Label and value in line 1
PrintDebugValue( “emaSlow_Past: ” ,( string )emaSlow_Past, 2 ); //Label and value in line 2
PrintDebugValue( “emaFast_Past: ” ,( string )emaFast_Past, 3 ); //Label and value in line 3

if (emaFast_Past > emaSlow_Past
&& emaFast_Current //Check if slow MA and fast MA crosses
<
PlaceTrade( OP_SELL ); //Place SELL-Trade for Strategy-Tester, function is located in BinaryOptionsStrategyFunctions.mqh
>

if (emaFast_Past emaSlow_Past) //Check if slow MA and fast MA crosses
<
PlaceTrade( OP_BUY ); //Place BUY-Trade for Strategy-Tester, function is located in BinaryOptionsStrategyFunctions.mqh
>

//+——————————————————————+
//| Get MA values for period, method, applied price and shift. |
//| For details of iMA() see https://docs.mql4.com/indicators/ima |
//+——————————————————————+
double GetValueForMA( int _period, int _shift)
<
return iMA ( NULL , 0 ,_period, 0 ,method_both,applied_price_both,_shift);
>

3.2.6 Use of external Indicators (ex4 files)

In addition an external indicator which stores its values in buffers can be accessed for the Binary Options strategy, even if only the compiled ex4-file exists.

Let us say we like to include the signal line of the KVO indicator https://www.mql5.com/en/code/8677 to place trades only if the signal line is over 0 for BUY trades and under 0 for SELL trades. Download the KVO.mq4 indicator and place the compiled (ex4 file) into folder \Indicators\Downloads ([path to your MetaTrader 4]\MQL4\Indicators\Downloads).

To compile the needed .ex4 file open KVO.mq4 in MetaQuotes Language Editor and click on button “Compile” or just restart your MetaTrader 4 after the file is stored in the described folder and MetaTrader 4 will do this automatically for you.

First we have to identify the relevant buffers which stores the relevant values to access. Therefore we press the button “Data Window” in MetaTrader 4 to show all available buffers of the used indicators and drag the KVO indicator on a chart. By hovering the cross over the chart (press mouse-wheel on chart to bring up the cross) the buffer values of the indicator of the hovered timeperiod will be shown in data window:

The data window labels tells us the second buffer value of the indicator stores the signal line. If buffers of indicators did not have labels, we can find the right one by comparing the buffer values with the displayed value under the cross in the chart and indicator. Buffers of an indicator starts with 0, so we have buffer value 1 = buffer 0, buffer value 2 = buffer 1 and so on and we have to access buffer 1 to get the signal value.

Next we have to know all input parameters of the external indicator we like to access. By draging the indicator on a chart, we see all input paremeters:

Let us further say, we like to access the indicator with (its default) values: 34, 55 and 13. We use a helper function (based on iCostum), wich provides us the possibility to get the values of the indicator with parameters for buffer and shift, while shift 0 will be the value of the current candle, shift 1 the value of the last candle, shift 2 the value of the second to last candle and so on. In addition we temporarilly store the values of the indicator buffer and enhance the if-condition of the strategy:

//— input parameters
input int period_fast = 5 ; //Fast MA value
input int period_slow = 10 ; //Slow MA value
input ENUM_MA_METHOD method_both = MODE_SMA; //MA method
input ENUM_APPLIED_PRICE applied_price_both = PRICE_CLOSE; //MA applied price

//+——————————————————————+
//| Place your Trading-Rules here – see example below. |
//| StrategyTester will call this function to place trades. |
//| DO NOT: |
//| – Rename function |
//| – Add function paramaters, e.g. CheckMyRules(int a) |
//| – Change function return type, e.g. int CheckMyRules() |
//+——————————————————————+
void CheckMyRules()
<

//Store MA values with shift=0 (current candle) -> current candle,
//call helper function GetValueForMA() to get the value – see helper-functions below
double emaSlow_Current = GetValueForMA(period_slow, 0 );
double emaFast_Current = GetValueForMA(period_fast, 0 );

//Store MA values with shift=1 (past candle) -> last candle,
//call helper function GetValueForMA() to get the value – see helper-functions below
double emaSlow_Past = GetValueForMA(period_slow, 1 );
double emaFast_Past = GetValueForMA(period_fast, 1 );

//Store signal value (buffer 1) of KVO indicator from current candle (shift 0)
double kvoSignal = GetValuesFromIndicator__KVO__( 1 , 0 );

PrintDebugValue( “emaSlow_Current: ” ,( string )emaSlow_Current, 0 ); //Label and value in line 0
PrintDebugValue( “emaFast_Current: ” ,( string )emaFast_Current, 1 ); //Label and value in line 1
PrintDebugValue( “emaSlow_Past: ” ,( string )emaSlow_Past, 2 ); //Label and value in line 2
PrintDebugValue( “emaFast_Past: ” ,( string )emaFast_Past, 3 ); //Label and value in line 3

if (emaFast_Past emaSlow_Past //Check if slow MA and fast MA crosses
&& kvoSignal > 0 ) //Check if signal value of KVO is over 0
<
PlaceTrade( OP_BUY ); //Place BUY-Trade for Strategy-Tester, function is located in BinaryOptionsStrategyFunctions.mqh

//+——————————————————————+
//| Get MA values for period, method, applied price and shift. |

//| Parameters: |
//| int _buffer – indicator-buffer (starts with 0) |

//+——————————————————————+
double GetValuesFromIndicator__KVO__( int _buffer, int _shift= 0 ) //Change “__KVO__” to indicator name
<

return (
iCustom (
NULL , //NULL for current timeframe selected in tester – NO CHANGES NEEDED
0 , //0 for current symbol selected in tester – NO CHANGES NEEDED

//BEGIN EDIT
“\\Downloads\\KVO.ex4” , //Filepath and filename of the indicator (*.ex4 file)
//BEGIN INDICATORS INPUTS

//END EDIT

_buffer, //Buffer index (begins with 0), _buffer is adressed over function parameter – NO CHANGES NEEDED
_shift //Shift (0 for current candle), _shift is adressed over function parameter – NO CHANGES NEEDED
)
);

It is also possible to enhance the input parameters of our strategy indicator with the values for the used KVO indicator and set the values in helper function by variables. As this tutorial should be just an example and “as simple as possible”, this variant is not shown.

The following video shows how to run a backtest of your Binary Options strategy in Strategy-Tester of MetaTrader 4:

  • Start Binary-Options-Strategy-Tester in Strategy-Tester of MetaTrader 4 and set the input parameters

6. FAQ

Question: Why do you show an example of a non profitable Binary Options strategy?
Answere: This is just an example how to build a strategy in an Indicator to communicate with the Binary-Options-Strategy-Tester utility in marketplace to test and improve your strategy.

Question: Binary-Options-Strategy-Tester stops after the exact amount of losses with error “Array out of range”. Why?
Answere: Binary-Options-Strategy-Tester can rise an error after x losses to stop Tester and to analyse the situaion on the chart. If you do not want to, just switch off the option in settings.

Question: No arrows appear on chart after I draged my indicator with a working strategy on it. What happened?
Answere: You have to enable “Allow external expert imports” on the “common” tab while you drag your strategy-indicator on the chart (log message will show an error in this case).

Question: No arrows appear on chart after I draged my indicator with a working strategy on it with “Allow external expert imports” enabled. Why?
Answere: A strategy has to call a function of Binary-Options-Strategy-Tester to place virtual trades. Related to the MQL4 license concept this only works if the product has a working license. Therefore you have to purchase the product.

Question: No arrows appear on chart after I dragged my indicator with a working strategy on it and I got errors like “Cannot call ..” or “Cannot load ..” in the log of MetaTrader 4. What can I do?
Answere: Use the latest version (greater v1.00) of BinaryOptionsStrategyLibrary.mqh. Check version tag in code of your BinaryOptionsStrategyLibrary.mqh and see changelog v1.01 of BinaryOptionsStrategyLibrary.

Question: I see no results on Strategy-Tester tabs “Results”, “Graph”, “Report”. Where I can see the results?
Answere: Strategy-Tester of MetaTrader 4 can not handle Binary Options so these tabs con not be used. Therefore this utility calculates all wins and losses and prints the results on the chart.

7. Miscellaneous

As I need a possibility to test Binary Options strategies automated in Strategy-Tester of MetaTrader 4 for long time periods in a short time and to do foward tests on the chart of the broker, this utility was build. I have spent a lot of time for the concept and the implementation of the Binary-Options-Strategy-Tester as well as for the documentation. Maybe there is a better way to do it and maybe some improvements will bring it closer to fit the needs of you. So please feel free to contact me for ideas for improvements!
