I've been using it off and on for about a month. I've had a decent amount of success. I use it with gbp/usd, eur/usd, usd/chf, usd/jpy. It's suicide when price get to the tunnel cause it can whipsaw you to death. I still havent found a filter that will avoid it. But when you can catch the trend it's a great system. I use the 1hr tunnel by the way.
