OPTIONS PROFIT CALCULATOR: Find and edit option strategies in real-time with our options profit calculator to gain a visual understanding of your trades. OptionStrat's strategy visualizer is used to find the potential profit and loss at various prices, as well as show how your trade is affected by implied volatility, time decay, and other factors. The strategy visualizer makes it easy to scroll through various strikes and expirations to build an options strategy. Nearly any strategy can be created, including strategies with underlying stocks like covered calls, or multiple expirations such as double diagonals. Over 50 strategy templates are available to choose from, each with a handy setup chart and description. STRATEGY OPTIMIZER: Automatically calculate the best strategies given a target price and expiration date. The options optimizer will search through thousands of potential trades to find which strategies maximize returns or chance of profit (or somewhere in between). UNUSUAL OPTIONS FLOW: OptionStrat Flow scans the market to uncover large and unusual trades as they happen, giving you insight into trades by institutions and other smart money. Not only do we show large call or put purchases, but we detect if the transaction showed urgency or aggression from the buyer or seller to show you both sides of the market. We are the first to provide unusual options activity for complex strategy types. OptionStrat Flow detects spreads, condors, and other advanced strategies and categorizes them as bearish, bullish, neutral, or directional.
