Honestly, I'm not sure how to explain it....same big share ASK block moved around to discourage buying....sometimes chopped up to hide it, but the math reveals them. I suppose a shareholder seller could be doing that, but looks like MM games to me. I am more the investor than the trader, so perhaps someone else can verbalize better about MM ploys. It's just that I buy 2-3 days a week for our little group, and notice these MM signals, ploys, games ...whatever they can do to elicit ACTION....their life blood.
