Prop Firm Compliance Shield
Paste your Expert Advisor, pick your prop firm, and see which challenge rules it could break: daily loss, maximum drawdown, missing stop losses, weekend holding, news trading and martingale lot sizing. You get back your MQL4 or MQL5 source with a built-in guard that tracks the day's starting equity and closes positions before limits are reached.
Why EAs fail prop firm challenges
Prop firms usually measure daily loss on equity, including floating losses, from the balance at the start of the broker's trading day. Many EAs only check closed-trade profit, so a losing streak can breach the limit before the EA reacts.
Test before you use it
Compile the result in MetaEditor, run it in the Strategy Tester and on a demo account first. Set limits slightly below your firm's real limits. This tool does not guarantee you will pass a challenge.
