Model assumptions

  • Contracts are floored — actual risk is at or under your risk budget.
  • Percent-based daily limits are computed against the account size you entered; firms anchor the calculation to start-of-day balance or equity, which can differ once the account is in profit.
  • Slippage and commissions are not modeled — a real stop-out costs slightly more than the math.
