I must say that as an IB customer executing 8000+ trades a year in 2 accounts I have had only several bust/reconciliation issues. Just yesterday I was playing a somnolent DIA ,building in and out 200 shares at a time. With the slow action I routed 200 shares short to Amex (I know...they should be wearing orange) 2 cents above the arca/inet price. It was filled and the prices dropped, instigating a cover 10 cents below on the accumulated position. Great...some pocket change and hourly compensation to reward my sore ass sitting there watching it. Half an hour later a dialog box pops up saying that 200 shares have been revalued and my trade records erased that Amex fill leaving me long 200 from the previous cover. So now I am negative a handful of $ as the market proceeded down. The thoughts of "Big Deal...Amex bandits...serves me right for joining an out of market offer...etc "came through. I covered the difference to flatten the position chuckling at the piker experience. This would have been a forgettable blip on the days action except for the fact that IB called me on my cell phone advising me that they were adding back the 200 shares as they had attributed it to some logging error on the exchange....I am recounting this to emphasize my quiet astonishment at the fact that they would call me long distance (2 attempts) to inform me of they had corrected this by hand (even though it had showed up earlier on the P/L and summary) and felt the need to tell me personally. Understand that to me this series of trans actions could have been filed under CANDY ASSED and the commisions involved were ludicrously small and yet the resolution took effort and money (time) on their part to resolve. With the volume they do there it seems impressive that such a small issue commanded such an immediate and personal solution.
