It's not a big deal, but I am intrigued by a system that consistently gives such odd fills, and wonder what the design is that leads to these fills - I once got a fill, within nanoseconds, of 156, 156, 156 and 532. I don't believe there could have 3 traders with exactly 156 shares to buy or sell?
That is kind of strange. OTOH, I can't imagine why ISLD would have deliberately done this on purpose. It might (remotely) have been 3 different small investors who had $3000 (or whatever) in a stock and were dumping it. There are a number of asset allocation systems I have seen that involve divvying up your $$$ among 5, 10, 20 (whatever) different stocks, even if that means you end up with 156 of one, 22 of AOL, 19 of AMZN, etc. I have never seen what you have, but I have gotten partials of 47 shares (while trying to buy 1000!)
