Highly configurable options modeling platform to test the P&L of your strategies. It's completely free, has all the usual modeling functionality plus some usually missing pieces: configurable per-leg IV changes, slippage and fees, combo pricing and custom contract sizes. It's easy on the eyes and provides a decent experience on mobile devices.
Hey, guys! I'm Vitor, author of the ITANOS options P&L calculator.
I started trading options a couple of years ago and I've been unsatisfied with existing P&L calculators. They're extremely expensive and handicap most functionality behind a subscription, are pretty ugly and barely configurable.
So, I decided to build myself one. It supports all the usual stuff, plus:
1. Per-leg IV changes
2. Slippage and fees
3. Combo pricing
4. Custom contract sizes
IV changes and combo pricing are the really big ones. Failing to model a significant IV changes is the difference between a profitable strategy and a loss. Combo pricing's what you'll usually be paying on a real brokerage and you'll want to take it into account since it'll likely differ from the price of the underlying options.
