I have mb trading as live feed, and second connection esignal for forex historical data.
I have several forex chart (30 minutes, 60 minutes, 120 mnutes, 1200 minutes....).
each time i move from one symbol to another, ninjatrader reloads all historical data.... isn't there a way to have it keep already loaded historical data, without having to redownload them each time I switch symbol?
thanks,
Duval
