The Adaptive Relative Vigor Index was created by John Ehlers (Cybernetic Analysis For Stocks And Futures pgs 140-141) and it does a pretty good job of capturing the peaks and valleys of the underlying data. There are several ways to read this particular indicator so for long term trades then buy when it goes above 0 and sell when it falls below 0 or for shorter term trades then buy when the indicator line turns green and sell when it turns red.
Let me know if there are other indicators you would like to see me publish or if you want something custom done!
