Notice the "e" on the far left margin. I have been trying to find a Legend that describes the "e" and "w". I think someone posted it a while back on SH. They indicate something about the trade. Can someone comment?
Cross trading/frisbee trading? You bet! golfyeti and I had discussions on this previously. Broker preferencing allows brokers to "jump" the cue so to speak and trade with themself.

MM's make the market. So why can they control the SP? You bet they can! buy/sell signals...you bet! ~$0.10 swings daily are nothing for CUU and as we have all seen can rise or fall %age points more in a heart beat.
Good luck all!
