Thanks Lunch, for helping me get an understanding of iceberg orders. I guess you can't blame a house if they have a big buy or sell. No point in giving day traders a shot at easy money.

It is ironic that Credit Suisse was a huge seller when the debentures were being converted, and now they have been buying with Iceberg orders the last couple of days. Now I guess it is Citigroups turn.
