I turn your trading setup into an MT5 bot with your prop firm's daily and max loss rules built in. Try it free on demo first.

Your setup, automated, with your prop firm's rules built in. Send your rules the way you trade them: text, screenshot, TradingView script or EA. Within 24 h you get a free demo build: the Prop Rule Guard, or your setup as an MT5 bot that runs in the Strategy Tester and on a demo account. When you want it on your challenge or funded account, the live version follows. No profit or pass promise.
