For getting historical data from Interactive Brokers APIs, how should the request be called if one wants multiple months (say 6) worth of 1-min stock data?
I came across the following:
?- [Step Sizes](https://ibkrcampus.com/ibkr-api-page/twsapi-doc/#step-sizes). ?
It seems to refer to the maximum data request time window for each data size (1min, 30min, 1hr, etc).?
The linked table shows 1 Day duration for 1min bar size; does it mean for 1-min data, I can only get 1-day worth per request? But that will be only 390 (6.5 hours x 60 mins) bars. So for 6months worth, I have to send one request for each day??
- [Data type](https://ibkrcampus.com/ibkr-api-page/twsapi-doc/#historical-whattoshow), so Trade, Bid, Ask prices are separate and I need to get each per request, so 3 requests and then combine them?
Hence, I need to send 3 requests for each day, each day for 6 months?
