GrailMeter script - measuring the grailness of your robot
Almost every trader who is actively interested in automated trading and various Forex advisors has encountered the so-called Grails.
Experts who show phenomenal results over a historical period, but in real trading conditions show a completely opposite result, are usually called the “Grail” among exchange players.
As a rule, naive newcomers who are prone to the desire to make quick money fall into the Grail trap.
The situation is quite typical, namely, that a person, having seen phenomenal results in the tester, places an advisor on a real account and, due to increased trust and hope, quickly loses his deposit.
To avoid such situations, professional players always advise testing the Expert Advisor on a demo account before betting it on real money.
So, is it really impossible to determine the Grail in front of you or a real profitable robot by looking at one tester without a preliminary test on a demo account? In fact, the grailness of an expert is quite easy to determine, and the GrailMeter script will help you with this.
Installing the GrailMeter script
Before you begin the installation, you will need to go to the end of the article and download the script file. The GrailMeter script was developed for the MT4 trading platform, so for further work we will need to install it.
To do this, launch the trading terminal and enter the file menu. In the open menu you will need to find a line called “Data Directory”. After opening the data directory, you will see a list of system folders, among which you will need to find a folder called Scripts and drop GrailMeter into it.
After you close all folders and restart the trading terminal, the script will be ready for use.
Reasons for the appearance of Grails in Forex. Working with the GrailMeter script
As strange as it may sound, the Grails appeared because of our greed and desire for quick profit. It is no secret that the Forex market has become highly commercial, namely, if there are people who want to buy a profitable advisor, then sellers naturally appear.
However, simultaneously with honest developers, so-called scammers appeared who took advantage of the vulnerability of the trading terminal MT4 began to create and sell the so-called tester grails. The essence of the vulnerability of the strategy tester is that it does not store tick price values, but generates them independently based on partial data.
Thus, by including a minute chart and selecting all the ticks, the strategy tester simply comes up with price behavior based on the two extreme values of the opening and closing prices that it knows. Knowing the approximate algorithm for generating tick data, scammers create so-called tick robots that know in advance how the strategy tester will behave.
As a rule, Grails appear under the guise of scalping and pipsing robots.
Advisor or profitable robot.
You should pay attention to the closing and opening prices of trades by the expert. In order to implement the deception that we wrote about above, the advisor must close positions inside the bar, therefore, by studying the closing percentage of such transactions, we can draw a conclusion about this expert.
To save yourself from lengthy calculations, you can use the GrailMeter script. To get started, launch the strategy tester and test in visualization mode. After the strategy tester completes testing, simply drag the GrailMeter script onto the window where the visualization took place.
A window will appear in front of you in which, using columns, the screen will show the grailness of your advisor, and will also indicate the number of transactions opened and closed within the bar.
Unfortunately, it is impossible to understand which expert we are dealing with before purchasing or downloading it, but with the GrailMeter script we can avoid the effect of the profitability of the real account and the strategy tester without any risks to our deposit.
