Hi, using the IB plugin in 1 minute backtest mode I can get 1 month worth of data, but new data overwrite old data so that I always end up with ony 1 month backfill. Is there a way to keep storing data without loosing old one?
I think it can be done by exporting data with fput and then merging appropriately different files or appending data, but I would like to know if it can be done in same other AB built-in way. Thanks Ly
