This indicator was the basis for his Natural Market Combo which I will be publishing very soon so stay tuned for that. The idea behind all of his Natural indicators was to use the natural log of the current price in different ways. This indicator obviously focuses on the slope and it essentially becomes another which peaks when the upward momentum is gone and vice versa. Buy when the line turns green and sell when it turns red. I have added strong buy and sell signals in addition to the normal ones and strong signals are darker in color in comparison to the original lighter colors.
Let me know if there are any other indicators you would like to see me publish!
