Ehlers BandPass Filter [CC]

The BandPass Filter was created by John Ehlers (Cycle Analytics For Traders pgs 56-57) and this indicator only works well in choppy markets so I figured it would be useful for the scalpers out there. As you will notice it correctly identifies the peaks and valleys in the underlying stock data but it doesn't work as well when the stock is trending. The black line is a leading signal for the indicator and so I use that as the basis for the buy and sell signals. Make sure to experiment with this one and let me know if you find any better buy and sell signals to work with since I believe this is the first time I have seen this script published. Buy when the 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!
