#1 the opposite order: if an IB customer & TH are sitting on the exchange at the ask price, then comes along an IB customer to buy at the ask. #2: I didn't mean, but it would be interesting to know what would happen if customer A's order is being held on the IB server (to sell at the aks), and another IB customer places an order to buy at the ask price, will the fill be between the 2 IB customers, or will TH get priority to sell at the ask.Quote from kiwi_trader:
You seem to be asking two questions:
1. If an order has been routed to the exchange and another order from IB or TH arrives will it be filled internally rather than the exchange?
2. If IB will match internally rather than relying on the exchange then what is the queuing? Is it first in first out?
