Actually you are wrong. It is great strategy and it could bring high accuracy but it doesn't. Most of the people who uses this strategy fail. Because they have no idea how to be a trend trader. You can do a backtest and it will give good results but when you start to trade you will find out that it is not so simple. You want to know the reason? It is simple- people look only at the trend line (this is a mistake) and when there is a breakout they simply think it is time to open a trade in opposite direction. Huge mistake. You should look at the price - it will tell you the truth. Try to assess the trend phase. Market will return only when there won't be any strength to go further.
