Spread Analysis

This handles multi-leg options analysis for vertical spreads, straddles, strangles, and iron condors. You pass a symbol, strategy type, expiry date, and the relevant strikes, and it spits back JSON with cost, max profit/loss, breakeven points, and probability of profit based on implied volatility. The breakeven and probability metrics are legitimately useful when you're trying to decide between a bull call spread versus just buying the call outright. All timestamps use New York time since that's where markets actually operate. It wraps yfinance, so you're getting the same data quality and delays that come with that, but the strategic analysis layer saves you from building your own Greeks calculator.
