What this calculator assumes

  • Expectancy is win rate times reward-to-risk, less the losses. It is an average; a real run is streakier than its average.
  • The trades-to-target figure is the target divided by expectancy times risk per trade, rounded up. It is not a probability of passing.
  • The losing-streak figures are consecutive losses that leave the line still open; the loss that reaches it ends the day or the account.
  • The figures it opens with are an example. It runs in your browser and stores nothing.
  • A prop firm measures its own rules on its own server, in its own time zone, with its own rounding. This shows where you stand by the arithmetic above; the firm’s measurement is the one that ends an evaluation.
