I am interesting how to use python in mql4. can we use? how can use? and how can backtest and optimize it

When I try to optimize , I want to change these optimization limit but cannot change. why this happen

I want to count past 200 candles that they has highest standard deviation or lowest standard deviation value. double DeviationArray[ 200 ];           for ( int i= 199 ;i> 0 ;i--){     

I optimize EA , no result show , later I know ObjectFind() and ObjectGet() functions don't work at optimizing! but in this articles https://www.mql5.com/en/articles/1512 Special Features of Optimization Process Draw objects are not really set The

I optimize my EA. it take too long to pass data and not show result . Although it passed over 100 data , it not show result in optimization results. So I stop optimization , it show error as 2022.04.19 03:45:16.130    ZigZag
