I wonder if there are people here that swing trade (2-3 days to a couple of months) multiple markets, not just one. For example US equities through S&P500 (SPY or futures), corn, sugar, crude oil, gold, perhaps even some major currencies. I am thinking that if one has a good grasp of technical analysis and has traded one market with consistent good results, then he can improve his performance by applying his skills on more markets. The more uncorrelated the markets, the better. Now, I understand that not many individual traders will be able to do this simply because of insufficient capital, because the commodities futures are quite big. I have personally only traded the mini corn and wheat contracts, besides stocks. But now I will have access to much bigger capital (opm) so I can trade more markets. So what I am basically asking, is whether the traders with sufficient capital prefer to focus on one market (say index futures) or multiple markets?
