This video will explore receiving market data and historical candlestick data from TWS using the Python API. We will discuss the different functions available for receiving streaming updates, real time bars, tick-by-tick data, and candlesticks.
In addition, we will explore data modes available for receiving frozen and delayed data. In this context, we will again consider the API Contract class, introduced in the previous lesson. We will also discuss how a Contract object is used in each real time and historical data request.
Code examples will be presented which show the minimum Python code necessary to request streaming and historical data and display market data in the console. Finally, we will discuss limitations on requesting data, and the types of data which are included in IBKR’s real time feed as compared to the historical database.
