First of all LR Correlation needs to be calculated. This is done in this library https://www.mql5.com/ru/code/1081

And then return this value via OnTester, like here https://www.mql5.com/ru/articles/286

Thank you! It's a pity that MQL5 built-in software does not allow to "pull" LR Correlation using TesterStatistics().

bug - MathRound returns the type double instead of a logical integer.

in fact, it's still a bug - if we round a number, it should be an int. xD

FiftyStars: Bug - MathRound returns type double instead of logical integer.

See my similar question in the next thread.

FiftyStars: Because of this there is no way to explicitly(!!!) convert double to integer

See section about explicit type conversion.

bug - MathRound ...

An explicit type conversion helps from issuing warnings:

int i = (int)MathRound(1.24);

Help, it's not working, translated from 4.

Thank you.

From which line do the problems start and what exactly are they?

[[Deleted]]

In the strategy tester, it does not increase the lot size after a losing trade.

Once again, where do the problems start and what exactly are they?

Sorry, I don't know what to say, I don't know where the problem is, I know it doesn't do what I need it to do.

but when the engine won't start - what do they do?
