I don't know whether this is still the case, but ISLD used to open the stocks up for trading after the other ECNs. It would usually be just a few seconds, but I knew for sure that the ECNs opened up the stocks individually because on a few occasions it was several minutes between when all the other ECNs opened the stock for trading and the time when Island did. On one or two occasions those Island bozos forgot to release something in the postmarket, and it didn't trade until the following morning, even though it traded through the other ECNs.
