Ecn

hi there,

lets start a discussion on the pros/cons of various ECNs.
Long time ago, I was always using Island, so just migrated to NASDAQ after the acquisition and always been using NASDAQ from there.

I am not familiar with other ECNs but think that I should consider all of them to optimize my trades and understanding of the market.

How are the fees of the various ECNs? their liquidities/fills? speeds? etc?

Does anyone have a brief idea of the ECN market shares?
 
i think this is an interesting topic, i too am looking for more infomation on different ecns and their fees. i will try and do some digging and hopefully can contribute to this thread soon.
 
I've recently started at a Canadian prop firm and I'm interested in this question.

From what I've determined by browsing around here, lots of traders are now using EDGX to hit orders and I don't understand why they don't use EDGA with routing options.

EDGA is free to take and provide and I have been having success with fills. But then I am trading the Qs and other high liquidity ETFs. Is this the difference? Are traders using EDGX because they are trading thinner stocks?

I still use Island and my order goes in as ISLD but it goes into L2 as NSDQ.
