So I'm watching index futures. I often see large sell orders (say 200 NQ) being printed while prices continue to rise. I figure this may be institutional, but let's say the big companies break their orders up into groups under 100. I also see lots of sell orders with like 50-100 contracts being passed even tho price continues to rise. Don't institutions pretty much run everything? Why would price continue to rise when massive sell orders are coming in? I see the opposite with buy orders and falling prices. Now every once in a while I see something that makes sense to me, like a cluster of large sell orders at the peak of a trend, or a cluster of large buy orders at the end of a decline. But it doesn't seem like there's any consistency. I would naturally assume that lots and/or large sell orders would support a down trend and vice versa. What am I missing here? Also one more TaS question. I see a print with the volume, and then it has BidSize and AskSize. What do those have to do with the volume traded? Thanks.
