What changed
View or select a supported option contract and OptionsPeek uses the current stock price, strike, option price, expiration, and implied volatility already on the page. When those details are available, probability of profit is calculated automatically for a purchased call or put—there is no separate POP form or duplicate contract entry.
The calculation uses the premium-adjusted expiration breakeven rather than the strike alone. Changing the entry option price updates both breakeven and the modeled probability.
How to use it
Use probability of profit as one expiration-focused planning input beside premium paid, scenario-date P/L, Greeks, and market quality. It answers a different question from Delta and from probability of finishing in the money.
The percentage is a model estimate, not a forecast or guarantee. OptionsPeek currently shows the long-position result for purchased calls and puts; short-option probability and risk require a different calculation.
