Market prices do not have a Gaussian probability density function
as many traders think. Their probability curve is not bell-shaped.
But trader can create a nearly Gaussian PDF for prices by normalizing
them or creating a normalized indicator such as the relative strength
index and applying the Fisher transform. Such a transformed output
creates the peak...
Direct port of the original Fisher Transform to TradingView: media.johnwiley.com.au
This might be better suited to be combined with other indicator to be effective, such as the Fisher Transform of RSI.
I hope you have found this useful :)...
