Hey, I'm up for dinner!
It doesn't show yesterdays trade chart, but I think the first trade was a sell for the 650, then it was all buys until lunchtime - when it went mixed buy/sell for the afternoon with a buy at EOD. The two columns on the right show the mix. The 650 was consistant throughout the morning. When the bid/ask is 18/20 I think there are probably periods where the buy/sell can be 19 if the activity is up. If everyone is trying to buy/sell at 19 - nothing gets filled.
On my TDA charts, the 10 day chart is the longest time frame I can use and still zoom down with 1 minute periods. On the 9th I put in a 250K buy at pretty close to opening bell, but it took a while to fill. When it did it was in one block. There where three small trades earlier. The software is kind of limited. Gave me a chance to check the other days and goof around with the zoom tool..:)
I don't see much of a pattern, other than at opening or after long blocks of low activity the trades tend to ramp from unreasonably low volume up. If the blocks for that day are large, these ramp transactions are larger. It might be a way the MM try to build interest, or it could be the trading is so light they try to close loose ends as they come.
This is my first stock where a .0001 change really gets my blood pumping..:)
