PS Trader is a nightmare- Resource hog and it never works right. On OCO orders, the other side of the trade never gets cancelled, even though it is supposedly linking the two orders. I'd love to hear anyone elses experience with this add-on.
Here is a complete overview: http://www.tradingtechnologies.com/plug-ins.aspx http://www.tradingtechnologies.com/documents/PSTrader.pdf Apparently TT decided to offer more than one plug-in to manage OCO orders.

Please read my previous post about the latest XTAPI about PSTrader fixes; also check the latest version for TT 7.x; it's more up-to-date than 7.1 (at least 7.3).
Dandxg: You are using NT with a Trading Technology feed? Have you notice a big difference in fill speed after switching over to the TT feed from whatever you were on before? Do you think a trader would be better off with NT with a TT feed as compared to X-Trader especially if trading 25-50 ER contracts ??
No the fill speed as about the same. I came from Dorman Zen Fire. Both good, but I think Velocity has more folks on the trade desk. They are still working out some bugs in the fix adapter though. It goes down sometimes, but it's up most of the time. If you are trading that many contracts I think you can justify TT pro. I don't yet trade that many contracts per trade although I do sometimes do 20 RT per day. TransAct is pretty good too, they now support SL orders, but they throttle data, which TT and Zen don't do. NT has alot of features for $50 a month, but it is no TT Pro, from what documentation I have seen on TT pro. If you can't justify TT pro's price NT with TT or Zen Fire feed is the way to go.
