Newguy, I use Amibroker and it can do what you want if I understood you correctly. Below is a screenshot of my Amibroker. The bottom tabs, called sheets, can be customized with TRIN, indicators, etc in reference to the Instrument selected to the left.

Silvermotion,
Thanks for the suggestion. However, that won't work for me because I don't look at price-based technical indicators (i.e. studies). I look at different markets (intermarket analysis) and market internals (TICK, TRIN, AD Line etc.). Those aren't considered studies, and thus can't be stacked.
