This morning I put in a buy stop order using IB. The order was to buy 1 ECZ6 @ 1.2801 on a stop. In a very slow market I was filled at 1.2824. I've emailed them for an explanation, but wanted to post here to see if anyone else has had a similar experience with them and what to expect. My experience with their customer service has always been horrible and I expect the same this time around. Any help or advice is appreciated.
