Hey everyone,

Like many of you heading into earnings season, I kept running into options calculators that were either paywalled, bloated with ads, or didn't properly show post-earnings IV crush.

I spent the weekend building a clean, lightweight web app: \*\*OptionsStrat Pro\*\*.

🔗 Live Tool: [https://vhomesai.github.io/options-strat-pro/](https://vhomesai.github.io/options-strat-pro/)

Key features I built into it:

• 1-Click Strategy Presets (Long Strangles, Straddles, Iron Condors, Covered Calls, Debit Spreads)

• Dynamic Post-Earnings IV Crush Simulator (see exactly how much extrinsic value deflates if volatility drops 30-50%)

• Expected Move & Overnight P&L Scenario Matrix

• Real-time Black-Scholes Greeks (Delta, Gamma, Theta decay, Vega)

• Client-side only (0 tracking, 0 ads, runs instantly in the browser)

It's completely free. Would love your honest feedback on what features or presets I should add next!
