As the title says...Do they? I like how retail brokers have the ability to click & enter a trade @ whatever the current market price is. I'm currently w/ Forex.com & like how their platform is set up. I just use E-signal to do all my chrarting 'n' stuff. Do ECN's have platforms like this? Also I see some support MT4...What is that? Where can I learn to operate that software & it's features? Thanks!
