@backtrader - Thank you again for the prompt response.
Lets say we want to simulate/backtest a
Strategy between any given dates eg. 2nd Jan 2012 to 1st Jan 2013, we need to calculate
todate for the DataFeed in such a way that indicator lookback periods are taken into account and Backtest starts from exact
startdate we wanted it to.
This is cumbersome and may be we can bake this login into
Cerebro such that irrespective of the
Data supplied to it, it can calculate indicators applying the relevant lookbak period or from the beginning of data feed and start the backtest from the
date we want it to start.
