Quote from Madgenius:
As a Professional option trader I don't use any of these brokers.
But if I had the choice of a broker who defaults to P-coast or the ISE.
I would choose the ISE. Best executions, Price improvement, fast cancels, tight markets.
I don't trust the P-Coast and I trade on the Amex.
Agreed - have had some nightmare cancel times on CBOE and AMEX, resulting in call to brokers to call the exchange.
PCX I find so illiquid exepct for a few block trades, would not use it unless I want to hold the market LOL, seems most don't hit it.
I always use ISE and love the fills, and instant cancels. Would also consider the BOX for the same, only used it a few times.
As for OptionsXpress, used them a few years ago, but you cannot trade actively with a website broker, not recommended for serious traders. And I don't think you can choose your routing on OptXp.
You need a software platform for instant action. TOS has one, I use Cyber.
The only downside I suppose to a software is more buggy, and downtime, but I have not found a problem using CyberTrader.
