RE:RE:ThisInstinet provides algorithmic trading strategies. The users do not pay per trade like we do. I have no idea what their endgame is and the Instinet doc below lists dozens of algo strategies. I still think it has more to do with price containment and accumulation than it does with trying to short the stock to oblivion.
I just hope at some point the algo gets turned off and price is allowed to run.
