The Two Trailing Drawdown Traps Explained

TRAP #1

Intraday High-Watermark Ratchet

If your account is at $50,000 with a $2,500 drawdown (floor at $47,500), and you enter a trade that runs up to +$1,500 unrealized profit before you exit, your floor permanently climbs to $49,000.

If you then close the trade at break-even ($50,000 balance), you now have only $1,000 of drawdown left instead of $2,500. You lost $1,500 of cushion without losing a single penny of real money.

TRAP #2

The Single-Day Consistency Trap

Topstep and MFFU require that no single day constitutes more than 40%–50% of your total profits.

If you catch a massive 100-point NQ runner and make $4,000 in one day towards a $6,000 goal, you cannot pass or request a payout until you trade additional days to dilute that single day's percentage. Nexus Armor calculates this threshold in real time to prevent accidental blowouts.
