Best Practices for Coding Market Data Functions with R

Best Practice

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, reqMktDepth and reqRealTimeBars functions.

Here is an example from the course Trading Using R in collaboration with QuantInsti:

Notice the instructor first defines the contract for which he wants to pull the streaming data on line 8.

Next, on line 11, the instructor applies the function reqMktData 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.

Visit IBKR Traders’ Academy for additional examples on how to code these functions and to take this complimentary course:
