What happens when you take the Fisher Transform of a Stochastic Oscillator? Well, you filter out all the stuff you don't want and are left with super-precise entries!
This indicator works especially well in with a trend-follower in a higher timeframe - iTrend, MAMA, Hull, etc...
How to trade: Use with another indicator to tell you the current trend. Take buy and sell signals as you would with the Stoch.
