The one thing I notice on those big lots, which I do think may be HFT generated, is if there's upward movement and they are near the inside bid and they're pulled, that's usually a sign of a reversal, although maybe not a huge one.Quote from NoDoji:
Chinook, I've tried my darndest to figure out if there's any meaning to the market depth on CL and can't find many patterns. One pattern that appears to have a high probability of success is when you see considerable size (100-500 lots) parked at a price level. Price has a tendency to gravitate toward that size and breaks through it more often than not whether it's a spoof order (disappears at the last second) or not (the entire size gets eaten up at that price). Only rarely does price simply stop there and reverse. ADD: Usually when it does, it's near a major high/low.
I know. Although I did a quicky 10 tick short scalp a few minutes ago. Has quite a bit of support there @105.70 so far.
