Risk disclosure

Options are risky

Options trading carries a high level of risk. You can lose all the money you put in, and with some positions, such as uncovered short options, more than that. Before trading options, read Characteristics and Risks of Standardized Options, which your broker provides.

Not investment advice

This software is a tool. Nothing in it or on this site is a recommendation to buy or sell anything, or investment, tax or legal advice. Gamma, flow and volatility figures are estimates built on assumptions, which the app states beside each figure. They can be wrong.

Not a broker

We do not hold your money and do not execute your orders. Orders go from your computer to your own broker, under your broker’s terms.

Algorithms and backtests

An algorithm does what its rules say, including when the market does something you did not expect. Backtests run on past prices and leave out real fills, slippage and outages: past results do not predict future results.

Demo data

Screens on this site show demo data, not real accounts or results.
