Does anyone else out there use the CHX. To me it seems like the most crooked exchange i have ever been a part of. I trade approximately 125,000 shares per day, almost all NYSE. I just started looking at some of the ECNs about a month ago. Island and Arca seem great but CHX constantly holds my orders. Even on a cancel they will sometimes hold the order for over 15 minutes. Anything over 30 seconds i feel is bad, anything over a minute seems ridiculous. Earlier in the week they held my order for over 3 minutes before filling me $250 outside of the market. I covered my loss on NYSE. Contacted my Clearing Firm, who then contacted the CHX exchange for an explanation. What i received was a bust on the trade after it went $750 the other direction. So the whole thing cost me $1000.00. I don't know how they even have space on these level II order entry screens. They are obvious manipulators. I have heard many similar problems have occurred to others as well. Please add story if you have had any problems with the CHX.
