Is it possible to put multiple symbols on a chart, and keep all but one of them hidden, and then utilize the hidden symbols when developing indicators? For example, one might have an indicator which takes data from internal measures of the market such as advancing issues, declining issues, advancing volume, declining volume, etc.
As some of you will no doubt guess, my questions are basically trying to figure out how much of Tradestation's functionality is transferrable to Ninjatrader.
Thanks,
Tasuki
