Thnaks Terry for your answer.. I would prefer to do it hard way ( second approach) but what I am not able to understand is this: since I roll/change contracts every month I use less than 30 day data windows for any given contract and I am going to have 120 contracts for a ten year window and my indicators that generate signals require 100 bars of data - how is the built in array of High/Close/etc being built then? I guess what I am missing is what data is being used to generate BUY in the second case scenario..
