I have already developed a custom indicator for the COT REPORT (Commercials net positions only for the moment) in NT. You can see it in http://www.jrbolsa.com/081214nt.htm
I'll go on developing other indicators related with the COT REPORT (their positions pencentualized, and the other groups: non-commercials and "other" along with the open interest and the position of the smartest boys related to the total open interes).
But there are two other greatest indicators: one which shows the seasonality and acts like a predictor and another one that does the same like the cot but for any other product like indexes or stocks in whatever market.
