I am currently developing an indicator that requires me to add 7 instruments (currency pairs) and plot 7 lines in a separate indicator window. The indicator runs just fine when it is added to a single chart window (not tab) but if you bring up a second, or third one and attach the indicator to them the platform freezes with no error messages whatsoever. You have to terminate it using the Task Manager in order to continue.
I wanted to confirm this so I made a test indicator that demonstrates this issue which I hope you can replicate. I am attaching here a copy of my test indicator (MultipleCurrencyPairsTest ). This indicator simply calls 7 currency pairs on initialization. On update, the indicator plots the Close price of the current chart on a separate chart window. It doesn't even touch the values of the currency pairs it calls and there are absolutely no fancy calculations involved but it is surprising that it still manages to freeze the platform. (or at least, my platform) Please find the ninjascript attached. Many thanks once again for testing.
Also below is the main part of my test indicator:
