sigmoid

octalide

Uses a weighted sigmoid function to gauge the difference between two moving averages. Useful as an additional confirmation source for following trends. The signal line hovers between -1 and 1, -1 being a negative delta and 1 being a positive delta. Using a minimum and maximum threshold, a trend can be identified based on how far the signal line crosses the...

This is an PS4 update to the Logistic Difference Indicator. It uses logistic function (sigmoid), which stabilizes the variance of data. The logistic function resembles the inverse Fisher transform. This version has a repaint/non-repaint switch and a scaling feature.

Introduction The inverse fisher transform or hyperbolic tangent function is a type os sigmoid function (sometime called squashing function) , those types of functions can rescale a result in a certain range and are widely used in artificial intelligence. More in depth the fisher transform can make the correlation coefficient of a time series normally...

Logistic Correlation is a correlation oscillator using a logistic function. A Logistic Function is a Sigmoid Function who stabilize the variance of data.The logistic function have the same function as the inverse fisher transform but with an advantage over it, the k constant can control the steepness of the curve, lowers k's will preserve the original form of...
