e.g.
Bid Ask
NYSE 6.05 5 NYSE 6.06 7
NYB 6.04 2 NYB 6.07 3
... ...
NYB 5.95 200 NYB 6.16 200
NYB 5.94 200 NYB 6.17 200
... ...
I means the Bid/Ask orders of "5.95 200"/ "6.16 200" will move quickly and aslo will disappear soon,but these orders will appear time to time in diffrent stock.They seems controled by computer program.
I want to know who use these program and where can i get informations for "machine order" .
Can i trigger them out?How to do?
