Finding per Higher Win Rate Settings For an Indicator

 

Hi I am New with MQL5

I know this is ask several times.

I have read that you must can create an EA that will spawn an indicator with different settings.

My question is how can I automate this process until I get the desired win rate without using external MT5 tools.

I want to ask first if this tools or functions or classes exist before I create an overwhelming coding in other platforms.

Thank you
