A Volatility order is an TWS-specific order that allows you to trade volatility by calculating the limit price of an option as the function of the option's implied volatility. You specify the option volatility and TWS calculates the limit price. When you enable volatility trading in TWS, the bid and ask values are displayed as volatility instead of price. You can also enable dynamic management of these volatility orders, where TWS updates the limit price based on movement in the underlying price, cancels the order if the underlying price moves outside a high or low price range, and transmits a delta trade for the underlying when the option order executes or partially executes.
