Ai MQL5 BOTS

have you guys tried to build mql5 bots using a artificial intelligence?

I was prompting on vscode some instructions for develope a bot for xauusd, thought that was to good to be true, they just automatically builds for you, but when I gonna backtesting suddenly 1000 dolares turno into 800, 100 dolares turn into 40.I just couldn't make it work. Someone has some thoughts about it?
