Adding/removing cash and resuming simulation

[polakowo]

Hi everyone! First of all big shot-out to @polakowo for making this great package.

My first question is about cash management. What I am trying to achieve is to add or withdraw cash on certain days of backtest. What is the best way to achieve that?

Secondly, I would like to save backtest (this is easy) and on the next day, when new market data arrive, load the backtest and extend it using new data. Is there a way to achieve this?

Thanks in advance!
