Scrolling thru a CL chart (probably other instruments also) there are often times where volume is just dead on each 1-minute bar (100, 156, 87, 172, 110).......................then out of nowhere the next 1 minute bar has a huge range with volume of 1500. Does anyone know what accounts for situations like that? Why would a large firm dump a bunch of contracts or short sell all at once & most likely get bad fills? I would guess it's something to do with hedging or options or something other than just plain outright selling, but I don't know. Does anyone know or know of any resources which explain the background/mechanics of the CL market? (This is not a news event I'm talking about, at least not any news event that I know of).
