If you lost today it might be a broker issue, xtreme scalping robots like this one are dependant on low spread and with zero broker interference, ie a true ECN as opposed to a fake ECN, put it this way if I was a broker Id interfere under the radar as much as possible to maximise porfits from clients, as most do ! However there are some ECN's that are honest...lol, yes true !! but you have to find them and then keep them to yourself :) What Tier level is your broker ? ie whats his pecking order in the market ??
Does your borker use plugins and do they requote, both are pretty much related, but just wondered if you knew or not.
Anyway I wish you good and profitable trading
