Quote from zmui: [presumably buy of DIA at 110.87] I use prophet.net chart. The time of the fill was at 1.27Pm 3/10/06.
On my chart, the high of the bar starting at 2006-03-10 13:27 is, indeed, 110.87. Looking at T&S, at 13:27:34, AMEX printed 400 shares @ 110.87. At the time, INET's offer was down at 110.79, so this was probably a technical violation of the trade-through rule (by 0.05), though the order probably was triggered when the NBO ticked up to 110.81 (at INET) at 13:27:30, so it was only $0.03 above the $0.03 window. I suppose you might be due an adjustment of $0.03 from AMEX, but you may or may not get it, and, realistically, it's unlikely that anyone would be interested in pursuing it for such a small volume (400 shares max at $0.03 = $12).
Bottom line - your stop was run by a penny and then the market reversed. Happens to us all, all the time
You might think of excluding AMEX and NYSE from your SMART routing - DIA is plenty liquid on INET, and you'd have gotten filled at 110.81 or better on INET when the stop triggered.
I got all this from IB's interactive charts, BTW .
BTW, I was using line charts for this and got tripped up by something I forgot about. At the same time as the 4x110.87 print on AMEX, there was a 4x110.79 print on INET (probly the spec picking up a free $0.05 . DIA@SMART trades on a 1-minute duration line chart shows 110.83 (the average of the two trades) for that second, while a candlestick chart shows the 110.87 high. FWIW, myTrack does the same thing with line charts.
Thanks for you insightful explanation and your advice on excluding AMEX and NYSE from smart rounting. Since you say this happen to us all the time, I probably would not held IB liable. But i have being trading about 3 years, this is the first time it happened to me.
