I found an edge.
Its taken me several years but I've isolated a trend change from a correction in both the Ed spreads and also the outrights.
Considering only the 4 main months, for the spread, H,M,U,Z.
I do TA and trade on the 2nd and 6th month.
Currently:
Ed Spread has been in a correction since the high on 8/7/2009.
Outright is also in a correction.
