jess and auto,
the "algorithmic" trading in this case isn't too complex as it attempts to keep prices within a certain band, it becomes complex when the algo trades in a range and basket of stocks but who knows?
also with stock custodians and brokers, trading can be aggregated daily without having to show individual trades.
if i was HH, or any other large fund and if i could influence auction price and activity, i probably would.
