Mmmmm! Assuming all concerned are using the latest software from CMC. Fairly fast computers. And are geographically not too far apart; all things being equal, there should be no discrepencies.
One theory could be that different geographical locations do have a part to play in this.
When I've been in the trading rooms. People have, as you say Riz, reported probs, then the next day a different group have reported problems.
Looking at the worst case explanation is that the sb's are blocking accounts on a rotational method and one should expect dificulties at some point, or simply it's a case of trading when everyone else is trying to place an order at the same time as the market moves.
Thousands of orders going over the 'net at the same time are going to hit a 'bottleneck' as they filter through, one order will be processed quicker than another order and the last orders will be requoted as the price has moved away from the intended trading price.
It would be interesting to find out how many orders are procesed per second by cmc, and whether someone trading in or near London where CMC are now located has a faster fill time then someone trading north of the border. ie, Watford.
Logically, there is a time differential surely. Perhaps a 'live' test one day in the trading rooms?
Also, the delay with mass orders going through can work in your favour; I've had stop orders get hit and carry on and not been actioned, then reverse and go in my favour where I've been able to then cancel the original stop order and put in another one. Leaving the original in place can lead to it being actioned at a later time when the price is nowhere near it. CMC will say that it took a while to get around to it. Removing it yourself and placing another one in the market at least gives you the benifit of having a 'timed' order in. ie, at 12.15 the market price was nowhere near the stop order. What it did 2 minutes before the order was placed is immaterial and the original stop order was cancelled and accepted so is no longer valid and ceases to exist.
There are ways around everything. One only has to look.
