Ehlers Adaptive Stochastic Indicator V1 [CC]

The Adaptive Stochastic Indicator V1 was created by John Ehlers (Rocket Science For Traders pgs 233-234) and this indicator uses the same calculations to find a cycle period that is then used for both the creation of the stochastic indicator but also for the smoothing to create a double smoothed stochastic indicator. Because it is calculated this way, this indicator is more reactive than almost any other stochastic indicator and provides clear buy and sell signals especially when the underlying stock is trending. It is interpreted in the same way as a normal stochastic indicator so great buy signals are when the indicator is below the oversold line and starts to move up and vice versa. Buy when the line turns green and sell when it turns red.

Let me know if there are any other indicators you would like to see me publish!
