The spread
Payoff at expiration
Note where the line goes flat on the left. That floor is the long $90 put doing its job, without it the line keeps going.
Pick an outcome
+$150
Both legs expire worthless. You keep the full $150 credit. The best case, and the only one where nothing is settled.
The numbers
A cash-secured put at the same strike would tie up $9,500. This spread requires $350, the same directional view for a fraction of the capital, in exchange for capping the profit at the credit.
The theory behind it
- Bull Put Spreads: A CSP That Costs LessBuy a put below your short put: capital collapses, so does premium. Compare both directly.
- How Multiple Legs Become One PayoffAdd legs one at a time and watch the combined curve assemble from its parts.
- Spread or Cash-Secured Put, on the Same ThesisThe same view at a tenth of the capital, and without the outcome the wheel depends on.
This simulator models outcomes at expiration from the inputs you supply. It fetches no market data, and the prices you type are not quotes. Real results differ: assignment can happen early, spreads and commissions are charged on every leg, and a position rarely travels in a straight line to the outcome shown.
