How does backtrader manage stocks which have delisted (i.e. their data stops at a specific point in time in the past). Does it assume zero return? or take the last value of trading as the completion of trading and return?
If not, how should I manage these stops? fill all data forward (so that its final price is the same every day into the future?
@cwse I am not an author, but based on the
btdescription - doesn't manage at all, which is usual for back testing and trading software. Such events are managed by data providers or by trader's database.
If the stock is delisted, than the price is 0.
Easy. If not data comes in, no data is delivered.
