I recently upgraded to the latest version of TT. when I execute a 1 lot in seems very fast, normal i would say. However when i execute something larger, lets say 50 or more it seems to que my orders in a strange fashion. If i sell 50 and there is another 50 lot on the bid it will fill the order quick. but if there are alot of one and two lots this is when the slowness happens. it takes almost two full seconds for the order to get filled...and you can hear it going off like a slow slot machine. The TT rep has been out and our tech guys have all witnessed this..... yet no one can figure it out. Its not set to iceberg. once the merc gets the order it is executed on their end very quick. My machine exceeds all the specs. i am currently on version 6 and it is still very fast...as soon as i switch to version 7 the slowness happens? i also have 3 other guys in the same pod as myself and they are not experiencing the slowness that i am? (they are on version 7). we have been working on this for a week and still no solution. anyone experience this? i HAVE to be one the new version to trade YMs on monday even though TT has extended our license for version 6. sorry for the long post...any help would be greatly appreciated. jim one more thing...if i do two fifty lots back to back ...i mean as fast as i can click..it wont even send the second order to the merc until the first one is completely filled. i can actually see it happening...something that never happened on the old version. thx
