Compact Marketdata
Compact MarketData typically refers to a condensed or summarized version of market data for financial instruments. It provides essential information such as the current price, bid-ask spread, trading volume, and possibly a few other key metrics. This condensed format is often used in situations where real-time updates are needed, but only a limited set of essential data points are required, such as in mobile trading apps or quick market overviews.
To get the compact marketdata, the first step is to subscribe the instrument for which the data is required.
