Basically it works the same as following a trend with MVA and LMVA, when the indicators are under the trend they show a bullish trend and vice versa, it must be followed under 5 min TFand it pays back, it really does, to work under smaller TF can be tricky because tickers and 1 m change fast and randomly, the only problem i´ve faced following supertrends these way is that by when a bullish or a bearish trend end at a 5 min TF some of the profitt has gone, believe me, it allways pay back.
By the other hand dont ever forget markets behave random and their behaviour is not scientific.
