Optionscanner

Price any options trade with up to eight legs: maximum profit and loss, breakevens, net credit or debit, the model's chance of profit at expiration and the expected move. Pass a strategy name (for example iron_condor or bull_put_spread) to build standard legs from the stock price, or pass the legs yourself with strikes and prices. Ask it for the max loss on a spread, the breakeven on a straddle, o

What a trade is worth if the stock moves, time passes or implied volatility changes: profit or loss on a chosen date at a chosen stock price, the same at expiration, and the change for one more day, one more volatility point and a one dollar move. Use it for questions like what happens to my condor if the stock drops ten percent next week.

The eleven standard structures the calculator knows (long call and put, covered call, cash-secured put, the four vertical spreads, iron condor, straddle, strangle), each built on an example stock price with its legs, maximum profit and loss, breakevens and chance of profit, with a link to open each one.

The one and two standard deviation price ranges the options market is pricing for a stock over a horizon, from the stock price, implied volatility and days ahead.

Bull put or bear call credit spread figures: width, maximum profit and loss, breakeven, return on risk, credit-to-width, and the model's chance of profit when implied volatility and days are given.

How many contracts fit a risk budget: account equity, the percent of it risked per trade, and the worst case per contract give the dollar budget, the contract count and the share of equity at risk.
