Description & Settings

In Tester during optimisation you may encounter passes crashing due to memory shortage.
calculate such emergency passes. However, it is difficult to evaluate all the many variants of input parameters for heavy memory consumption by the Expert Advisor.
Also recommended: Reporting Memory Leaks in Strategy Tester - similar library with strong performance on MetaTrader 5.
You need to find potentially problematic configurations of input parameters of an existing Expert Advisor. And then figure out the causes.This simple library allows you to track the dynamics of changes in memory consumption in a rather simple way.
Example.
To illustrate, let's take a laconic EA and add a few lines to it (highlighted).
The Expert Advisor simply increases its array.
Result.
The picture shows the result of the optimisation.
The memory consumption measurements are similar.
A single pass of the top set will produce this.
Scenarios.
The library allows you to find excessive memory consumption by the Expert Advisor and further investigate the causes in debug mode.
The less resources the Expert Advisor consumes, the more opportunities for optimisation: increase in the number of testing agents - speed of optimisation.
