Event Trading

Market Data

Requesting market data for event contracts will follow the same request structure as for any other security type.

Noted in our [Contract Definition & Discovery](/tws-api/doc/event-trading/contract-definition-discovery/introduction) section, ForecastEx instruments do not support buying and selling. Therefore, “BID” and “ASK” values will not correlate to buy and sell values, but the “Highest Bid” and “Buy Yes Now at” prices for the Bid and Ask respectively.

Because “BID” and “ASK” do not correctly directly to Buying and Selling, historical “Trades” nor real-time “Last” prices will not be available.
