I don’t get to spend a lot of time at a desk during the warm season. I get a lot of brain farts about inter market relationships and the iPad version of my trading apps doesn’t allow two instruments on one chart. I’m looking for a web based charting service that would allow me to display some pairs like DX vs Soybeans on the same chart. This would help me look for correlation and divergence between specific futures contracts, currencies, interest rates, specific stocks, and indexes. iPad compatibility is what I’m looking for. Any suggestions?
