TDT
You can go to Stockwatch and check the trades, one house is TD sec known to use Algos there are a few more.
Legal but knowing they are active in a stock can be very handy, they don't know the true value of a stock, and they can be used to drive a stock down.
You and I traders can't pull the trigger that quick even with stops, those quick drops and rises on PM are NOT you and I trades.
