In the last week, I've had the following problem:
1. Comsec telling me "at market orders are not permitted outside trading hours"... At 11am on a Monday.
2. Comsec executing my trade, then telling me it's still in market, for another 40 minutes
3. Comsec covering my short, then executing the same order again, putting me in an equivalent long position.
All 3 times, Comsec have admitted fault. I am using a mobile to trade, so I guess accidental replays and out of date websites are possible, but has anyone else had these problems?
