Can somebody help me in identifying good day trading futures instruments and their symbols in tradestation. e.g mini gold what is the symbol, oil symbol , natural gas symbol ? I am already looking at e-minis s&p (ES), (nasdaq)NQ, (russell)ER2 and (dow)YM but pretty much they seem to be moving in same manner. I know Er2 is little much trending then others. But I still feel trading just 1 out of them is good enough. I am trying to diversify my edge and want to see if it also works(with minor modification) on other instruments.
