Hi there, I've traded a few times on the main markets and thought I'd give the AIM market a go, just as a learning process really. I found a stock that was available, and to me it looked like there were 3000 shares available (I looked at the ask volume) I also put a limit order in at 440 which was the ask price too. My order was processed and then went into my outstanding list. This hasn't happened before as normally they just go through immediately. I'm guessing this is to do with it being the AIM market but I don't understand why. Is somebody able to explain please?
