Join the IBKR Traders’ Academy team and learn how to code different types of market data. Get practical examples on how to retrieve streaming and historical data with the reqMktData<\/code>, reqMktDepth <\/code>and reqRealTimeBars <\/code>functions.<\/p>\n\n\n\n

Notice the instructor first defines the contract for which he wants to pull the streaming data on line 8.<\/p>\n\n\n\n

Next, on line 11, the instructor applies the function reqMktData <\/code>function which connects to the TWS, and assigns the security objects as the arguments. Observe that upon execution, the algo app returns a continuous stream of market data.<\/p>\n\n\n\n
