Account cumulative PL

[alex.nt]

Hi,

I am adding to 2 chart 2 instances of the same strategy (with different parameters) and would like to update certain parameter P in both if any of these two strategy loses.

I.e. if instance#1 exits with loss => I update BOTH instances' P

For realtime I can use GetAccountValue(AccountItem.RealizedProfitLoss)

What can I use during historical backtesting?

alex,

Unfortunately this isn't supported at this time. I would suggest doing some research in the forum as likely you could find a work-around.
