I'll bet the momo guys keep their eyes on the open interest numbers coming out of the COMEX in gold/silver. Seems to me that's one way to get a clue whether or not the cartel is beginning to cover or continues to take the other side of any uptrend.
My guess is that these momo guys look at this stuff to get an idea when the coast is clear to pile in on the long side. As noted before, the more the cartel shorts, the more likely a take-down is coming sooner or later, imo. Can't count the times that's happened. When they start covering, no where to go for gold and silver but up.
