Apex 50% Consistency Rule Calculator

Apex 4.0 blocks your payout if any single trading day makes up more than 50% of your total profit. Enter your total profit before today, your best day so far, and today's running P&L — this calculator shows your live consistency share, exactly how much more you can bank today before you breach the cap, and the grind target if you already have.

How this is calculated

The flat consistency rule compares your biggest single day (including today, if today is positive) against your total profit including today. If that share exceeds the cap, the payout is blocked until the total grows enough to dilute the big day.

share = max(bestDay, max(0, today)) / (priorTotal + today) headroom = max(0, (cap × priorTotal − (1 − cap) × max(0, today)) / (1 − cap)) grind = biggestDay / cap // only when share > cap

headroom is the most you can still add today before your day becomes exactly cap of the new total. Past the cap, grind is the total profit you need (with no bigger single day) for the big day to fall back under the cap.

Big green days create homework: every outsized winner raises the total you have to grind out before it stops dominating your profit.

Worked example (50% cap)

  1. Prior total $1,650, best day $760, today +$1,470.
  2. Biggest day = max(760, 1470) = $1,470. Total = 1650 + 1470 = $3,120.
  3. Share = 1470 / 3120 = 47.1% — under the cap, payout still live.
  4. Headroom = (0.5 × 1650 − 0.5 × 1470) / 0.5 = $180 more you can bank today.
  5. If today runs to +$2,900 instead: share = 2900 / 4550 = 63.7% — blocked. Grind target = 2900 / 0.5 = $5,800 total, with no bigger day.
