How the numbers are calculated

Max profit is the net credit times 100 shares per contract. Max loss is the distance between the two strikes minus the net credit, times 100. The breakeven is the short strike plus the net credit.

Probability of profit is 1 minus the short call delta. The page shows it only when you enter a delta.

Short call at $105.00, long call at $110.00 and a net credit of $1.50 per share. The strikes are $5.00 apart.

Max profit is $150.00. Max loss is $350.00. The breakeven is $106.50. With a short call delta of 0.30, probability of profit is 70.00%.
