Coupled Polygamma Function

5 375
The polygamma function is the (n+1)st derivative of the logarithm of the gamma function where n is the respective order. An approximation of this derivative at order n=1 is taken, and when its real coefficients are used with an ATR, exhibits interesting behavior, in particular when 2 lengths coupled together, prevents whipsaws as both are needed to break for there to be a change in the trend-bias. When a long or a short signal is printed, this doesn't suggest a long/short action needs to be taken, only a bias is suggested. Wait for a pullback before entering if a long is triggered, for example.

There are 2 modes. Linear is used for prices following a non-polynomial market structure (y=mx+c). Accelerated is for more parabolic marker structures, followed by decaying prices (DOGEUSDT HTF is a great example).
