Fast answer

Paying $0.18 more than intended on five contracts adds $90 before commissions and reduces the same amount from the planned reward.

The useful question is not whether one metric looks good. It is whether the full risk, reward, cost, timing, and recovery math still make sense when the trade behaves badly.

Action checklist

  • Know the intended price before sending the order.
  • Compare the fill with bid/ask spread.
  • Recalculate breakeven after slippage.
  • Track repeated slippage as a strategy cost.
