Educational tool, not advice. It does arithmetic on the numbers you enter. It can't predict whether you pass. Firm presets use rules we verified on each firm's site; always check the firm's current rules.
The account size at the start.
How far the floor sits below the start (or below your peak, for trailing types), in dollars.
Optional. Many firms stop trailing once the floor reaches the start plus this amount (0 means it locks at the starting balance). Leave blank for no lock.
Your days
For each day: your P&L at the close and the best open P&L you reached during the day (that peak is what moves an intraday floor). Use a minus sign for losses.
closing balance (ring = intraday peak) static end-of-day intraday; ✕ marks a breach
Breaches are checked against your closing balance. Real firms also check during the day, so a dip below the floor before the close can fail you sooner.
