Who it is for
Options traders sketching multi-leg structures who want the payoff picture before placing anything.
OptionsCalc
Multi-leg options strategy modelling with payoff charts
Overview
What OptionsCalc does
OptionsCalc builds an options position from a described trade idea and draws the result. A request such as an iron condor on a given ticker returns a payoff diagram, the associated risk metrics, and scenario analysis run across both price and time.
The Greeks are covered in full, delta, gamma, theta and vega, alongside implied volatility. Profit and loss appears as an interactive heatmap rather than a single static curve.
Multi-leg construction is supported, taking in spreads, condors, straddles and butterflies. Sample prompts include pulling an SPY option chain for a stated expiry, breaking down the Greeks of a strategy, and building a 30 day iron condor on SPY.
What stands out
The profit and loss heatmap across price and time is the distinguishing output, since a payoff diagram alone fixes one variable.

Where OptionsCalc is listed
OptionsCalc is listed in the ChatGPT apps directory only. One Dot Design LLC has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
