"In time series analysis, dynamic time warping (DTW) is an algorithm for
measuring similarity between two temporal sequences, which may vary in
speed. For instance, similarities in walking could be detected using DTW,
even if one person was walking faster than the other, or if there were
accelerations and decelerations...
Kelly criterion methods.
the kelly criterion helps with the decision of how much one should invest in
a asset as long as you know the odds and expected return of said asset.
simplified version of the kelly criterion formula.
win_p : float, probability of winning.
rr : float,...

for example would retrieve a array with ,
the elements retrieved will be sorted by its first seen index in
note: float values have no precision option.

Side / Boundary Based All Types Swapper
- three automagical types for Arrays, Matrixes, and Variables
-- no signal : Long/ Short position autoswap
-- true / false : Boolean based side choice
-- Src / Thresh : if source is above or below the threshold
- two operating modes for variables, Holding mode only for arrays/matrixes
-- with two ...
A Magical little helper friend for Candle Math.
When composing scripts, it is often necessary to manipulate the math around the OHLC. At times, you want a scalar (absolute) value others you want a vector (+/-). Sometimes you want the open - close and sometimes you want just the positive number of the body size. You might want it in ticks or you might want it in...
intrabar_cross_value(a, b, step) Find the minimum difference of a intrabar cross and return its median value.
a : float, series a.
b : float, series b.
step : float, step to iterate x axis, default=0.01
Custom f_nDecimals() function returns precision of decimal numbers of the following forms:
const, input, simple, and series of the following types: float, integer, and string.
Error checking is performed for valid numbers and invalid values return NaN.
NOTICE: This is an example script and not meant to be used as an actual strategy. By using this script or any...
Method for Minkowski Distance,
The Minkowski distance or Minkowski metric is a metric in a normed vector space
which can be considered as a generalization of both the Euclidean distance and
the Manhattan distance.
It is named after the German mathematician Hermann Minkowski.
This script plots vertical lines on charts or indicators. Unfortunately pinescript is lacking a vertical line plotting function. Vertical lines are useful to mark events, such as crossover of levels, indicators signals or as a time marker.
After searching the internet for a long time and trying different scripts, this script is the simplest and visually the...
Perceptron Function for Neural networks.
function(inputs, weights, bias, activation_function, alpha, scale) generalized perceptron node for Neural Networks.
inputs : float array, the inputs of the perceptron.
weights : float array, the weights for inputs.
