When determining support and resistance on a Comex Gold daily or weekly chart, is the professional trader looking at the specific month's contract or the continuous contract? I have looked simultaneously at GCM08, GCQ08, @GC & @GC.P with support/resistance drawn in relatively the same place (a specific day's trading) and have come to the conclusion that an argument can be made for or against each theory. Obviously for historic S&R a continuous contract is needed since liquidity becomes an issue when looking back in time on the current month's contract. However, looking at the 2006 highs on @GC shows a much different picture than @GC.P (pit only). Gold actually traded up to and above $800 in 2006 but you wouldn't know that from looking at the continuous contract @GC. Any ideas?
