Simple Strategy follow the COT commercials COT index indicator shows the positions of the commercial traders.
My strategy is to follow changes on that index (high reading = bullish, low reading = bearish)
Its not an entry indicator but a setup indicator, so make sure to enter on traditional signals like double tops or trendline breaks...
I keep an updated list of the major futures instruments with LONG,SHORT,NEUTRAL readings:
