Let me start by saying this is not a 'bash IB thread', I'm generally very happy with them... BUT I've been getting some dreadful stop fills on IB Ideal Pro the last few weeks, 9 pips slippage on eur.jpy yen today, a similar amount a couple of weeks ago. Has anyone experienced the same problem or am I just being unlucky? I've set trigger to 'mid' but 3 times in the last 3 weeks I've had the price run through my trigger then execute on one occasion (according to T&S) around 8 seconds late, on two other occasions a couple of seconds late. I emailed support who confirmed there's an issue which they are looking into but I'm a bit miffed I'm still getting this problem 3 weeks later. My execution on eur.jpy today was 2 seconds delayed after the mid price triggered, 9 pips slippage on what should have been just two or three max. I'll close by re-iterating in every other respect I am very happy with IB and this issue doesn't affect every trade, but it is affecting some trades. Please let me know if anyone else is experiencing the same problem on ideal pro trigger to exeuction delays. Thanks.
