Is there anyone here that uses MT4 for institutional trading? How well is it working for you and which broker are you using.

I've used MT4 for years, now I'm wondering how well it works in an institutional setting (ECN Feeds). I'm actually looking for a program/script that bridges MT4 and ECN feeds. Something like this may be promising http://www.jd-soft.com/Products.html and no, I don't work for that site. I'm looking to find MT4 users who have ECN feeds

Thanks!
