read an article the other day saying some of the top specialists were doing 4 million keystrokes a day mathcing up orders. that's almost 9k keystrokes a minute.
unless, you're one of the biggest traders in that stock, i doubt they have time to notice.
Quote from Option Trader:
To do such a quantity would require highly sophisticated programming. I would imagine the program categorizes hundreds or thousands of different scenarios where statistics show traders are vulnerable and tend to lose money, and they can quickly make the necessary keystrokes one after the other, with one button.
Quote from putzzytheclown:
Every single order routed to the specialist has a unique tag number identifying the originating party.
They don't match up the orders manually, most use automated bots for that. Specialists manually match up large orders that hit the floor or when they want to screw some poor schmucks they know have a 1 penny tolerance on their trades.

like hydro said, the unique identifier shows the clearing firm. a bit suprised he thinks they can single out "the daytraders", since most clearing firms also host buyside instis and hedgies as well as trading firms. you know how many different organizations clear through penson, slk, gs, etc?

hehe, yes definitely, i'm sure the programmers who created the highly sophisticated automated trader-tracking-profiling-stat program would decide that the best implementation would be a keystroke macro.
as the nyse moves to hybrid a lot of the order filling will be done by algos. but for the most part it's still being done manually and has been for a long time. if it's not the specialist it's his clerk. your info is wrong.

how about actually doing a bit of research before posting assumptions as facts guys? http://hybridtalk.nyse.com/archives/2006/03/debunking_lump.php
