Consistency rule calculator

Many prop firms hold your payout if one day is too big a share of total profit. Check your best day against the rule — and see exactly how much more profit you need to comply.

How the consistency rule works

To stop traders passing on a single lucky day, many firms require that your largest winning day is no more than a set share of total profit (commonly 30% or 40%):

  • · Max allowed best day = Total profit × limit%.
  • · To comply, keep your best day at or below that — or grow total profit until Best day ÷ Total ≤ limit%.
  • · Total profit needed = Best day ÷ limit% — the total at which your current best day becomes compliant.

Shibiki tracks this live as you trade, so you know mid-evaluation whether one green day has quietly put your payout at risk.

FAQ

Is the consistency limit 30% or 40%?

It depends on the firm and program — 30% and 40% are the most common, but some use other figures or apply the rule only at payout. Enter your firm's number above.

What if my best day is over the limit?

You don't have to erase it — you just need enough additional profit on other days so that the best day falls back under the percentage. That target is the "total profit needed" figure.
