I placed a sell order (via comsec pro-trader) this morning at 10:25:35 but it didn't get processed until 10:25:50 - thats a 15 second delay between hitting the go button and the order getting filled and it was an at-market order. I watched numerous orders go through while it didn't go to market. I thought comsec had straight through processing, but I know sometimes they manually intervene as well (and 15 seconds is a long time so to me it seems like its had a manual review before placement?)
Normally when I place an order its instantaneous - I hit go and it appears immediately in the depth in what seems like under 1 second.
Just curious if anyone knows anything about this side of things and how it gets treated with comsec and/or other brokers? What are the criteria for manual intervention etc.?
(I've sent this question off to commsec as well so I'll put their reply up when it comes through).
