The real costA significant proportion of funded challenges fail for structural reasons, not analytical ones.
No single figure accounts for every failure, and execution quality is always part of the picture. But a meaningful share of challenge failures trace back to structural traps the trader never identified — not to bad entries or weak analysis. Three of the most common live exactly where MT5 stops looking.
Trailing drawdownThe limit moves with your equity.
Many firms track the drawdown from your highest equity, including open profit, not your starting balance. The floor rises every time you're up, then traps you in a band you can't see on any MT5 screen.
SO WHAT?You can be net profitable on the account and still breach, because the limit crept up behind you while MT5 showed nothing but green. The leading cause of structural failure, invisible by design.
Aggregated exposureSeveral accounts, one hidden bet.
Running multiple evaluations at once feels like spreading risk. If the same setup is on each, it isn't. Across accounts it becomes one system-wide exposure, and no single MT5 terminal can see the others.
SO WHAT?One adverse move breaches the drawdown rule on every account in the same minute. You don't lose one challenge, you lose the whole stack at once.
Cost & frictionCommissions and spread eat the limit.
Tight-stop strategies live and die on transaction cost. When spread and commission scale faster than the rules make obvious, the daily limit gets tested by friction alone, before the market even moves against you.
SO WHAT?A "small" cost per trade, multiplied across a scalping session, quietly walks you into a breach you'd swear you never traded into.
Every one of these is a number trending the wrong way before it breaks. ORYS is built to surface exactly that, while there's still time to act.
