Global Dictionary Question

I am attempting to code an indicator, I was considering using the Global Dictionary, which is part of TradeStation.

What I am looking to do is to detect if any divergences exist on time frames. frames. Eventually after testing and tweaking the code my eventual goal would be create and build a strategy, but for now what I looking to do, is detect divergence, and pass this off into a lower frame chart.

Any-one have any suggestions for doing this? or if the Global Dictionary would function for this?
