How to optimize an already profitable EA?

I've tested a lot of robots and found one that has been consistently profitable in the last 8 months by tweaking every possible setting on the live market.

I know these settings can be optimized further and way faster if I would just hire someone, or maybe use some tools - strategy testers?
I'm definitely not technical and know nothing about what to look for.

Can anyone recommend some tools to use for optimizing/testing?

I would appreciate any suggestion.

Thank you!

Good point!

I was just thinking that if I figured out some things by testing manually, that could possibly be way faster and improved way more with some software/tools.
