The COT data is very important for traders to understand. Go to barchartdotcom. In the upper left, click on futures. In the lower right, under Indices, click on commitment of traders. In the center left, click on DJI Mini-Sized (YM). The middle graph shows the positions of the Commercials (banks, etc), the Large Speculators, and the Small Speculators. The lower graph shows Dealer Intermediaries, Asset Managers, Leveraged Funds, and others. When you slide the mouse over the futures curve, a popup shows the COT data for that week. I watch the Commercials for long term trend/direction changes.
