ECN brokers have fast price feed and the spread changes constantly, so it is quite difficult to place profitable orders, but recently my programmer and I succeeded to create an ECN version of the ROBOT. We tested it with a number of ECN brokers and it works quite well with some, but not all of them.
"MT4 FX ROBOT" works best with brokers with low spreads, slow price feed and instant execution. Although generally ECN brokers are regarded as most reliable, not all systems work well with them and some Market Makers are very reliable too. I strongly advise you to open demo and real accounts with a few brokers. Don’t stick to one broker only, no matter how good it is. Check your systems as well as the "MT4 FX ROBOT" with a number of brokers, not only one. Opening a new account doesn’t take much time, but can give you enormous advantages
