Once datas have been added with adddata(), is there a way to adjust time period that backtest operates on?
I am working on my own version of a walk-forward optimization algorithm, and ideally I would just add all the backtest data with adddata(), and call run() with different todate, and fromdate. I don't see this as an parameter to run(), so what is the best way to do this, hacky or otherwise.
There are no such parameters to run. If you want less dates to be taken into account pass
todateto the data feeds.
