Interesting observation

for some months now I have been subscribed to a charting service that forcasts the 4 major pairs and gives buy and sell entry and exit alerts. They are intended to be trend trades and therefor more than daily. Large stops and limits. They have done quite well overall but I found them to be very inaccurate at the outset. So durring a lull in the day, I back tested their alerts and found that on all but one in a 30 day period if I had taken the opposite side and held for 30 pip or 5 day run which ever came first, I would have won on all but 2 trades. More than one way to skin a cat.
