Excellent research sketch as you are our resident forensic expert, a.k.a. Rob Kirby. As GATA often states, there are no coincidences in the gold market. I would say that the same suppressive computer algorithm has been applied to more than one of the top juniors. A closer look at the trading patterns shows that Jitney and Anonymous are also common sellers on both ECU and SGC. Knowing Peter Grandich, he definitely does his research before he makes his top call. Sounds like you have confirmed the presence of a serial suppressor. Too bad we don't have a police force or regulator to nab the culprit.
Great work - VHF
