Quote from 1000:
To trade a hybrid successfully, you need at least 2 entry points (accounts), possibly under at least 2 different names, because even after five years of some markets going from manual to hybrid to fully automated, the systems are still jinxed.
Most platforms are programmed to auto-switch off if certain trading parameters fall outside predefined limits, and it takes for ever for them to reprogram, sometimes a whole day.
It is possible to eventually ware out the specialists, who then give up trying to manipulate, but risk has to be reduced more than in non-hybrid systems.

Under Hybrid, orders shown have preference over floor orders. Are you saying that the specialist will be able to manipulate the price even more under the hybrid system:eek:

Why won't tape reading be possible? are they going to eliminate all crossed markets? Most of the tape readers in my office hit arca and what not, and I sort of felt that the NYSE didn't have jurisdiction over bosx, cinn and, midwest. But maybe they do?
Quote from Hydroblunt:
Because Open Book is gonna become Nasdaq Market Maker box and therefore you will not be able to see how the specialist handles seen limit orders.
It's going electronic and that is it. If you cannot trade Nasdaq, you are gonna have a lot of problems with the Hybrid. The big players want to dominate intraday with computers as much as possible.
