I have the following statement in my system code: Plot1 (LastTrailingATR). LastTrailingATR is dimensioned as Double. When I save the system I get the following message: undeclared variable: 'Plot1'. What am I doing wrong? Thanks, Bob

Plot statements only work from indicator plots, not systems or anything else. This is the same as TradeStation.

Is it possible on a Chart to add a bararray to it?

Hi, Yes it is. But you can't pass a bararray from a system to an indicator plot. Think of them as separate walled off functional domains. If that will change, it won't be for some time. What you can do is replicate the logic of your system in the indicator plot and so build and plot the relevant bararrays from there. Regards, Dave
