Any suggestions from experienced traders would be a big help.
What is the best servcice in terms of execution? I mean, seriously.
Broker takes order, forwards it to exchange. Unless you talk pit, there is simply NO DIFFERENCE at all between brokers from there on. The execution is done purely on exchange hardware without futher intervention from the broker.
So, unless a broker delays orders (slow architecture on his side).... how can there be a best broker for executions?
Re comission rates - that depends. Negotiate. If you do enough round trips, get an exchange membership
