Get bid / ask price and size on Interactive Brokers data feed

[marticols]

I am developing and intraday strategy that uses tick data from IB.

For the strategy is crucial to implement cumulative delta, which needs ask and bid data. For now i see that backtrader is only for OCHL related data with the exception of generic CSV data feed that have implemented a way to load ask / bid data.

In other posts @backtrader say that is possible to implement this to Interactive brokers.
(Re: Anyone using Backtrader for live trading). Why is implemented only for backtesting and not in live environment ?
