Library "MarkovChain" Generic Markov Chain type functions. --- A Markov chain or Markov process is a stochastic model describing a sequence of possible events in which the probability of each event depends only on the state attained in the previous event. --- reference: Understanding Markov Chains, Examples and Applications.

Library "FunctionProbabilityViterbi" The Viterbi Algorithm calculates the most likely sequence of hidden states *(called Viterbi path)* that results in a sequence of observed events. viterbi(observations, transitions, emissions, initial_distribution)   Calculate most probable path in a Markov model.   Parameters:      observations (int ) : array ....

Library "FunctionBaumWelch" Baum-Welch Algorithm, also known as Forward-Backward Algorithm, uses the well known EM algorithm to find the maximum likelihood estimate of the parameters of a hidden Markov model given a set of observed feature vectors. --- ### Function List: > `forward (array pi, matrix a, matrix b, array obs)` > `forward (array pi, matrix a,...

Library "FunctionDynamicTimeWarping" "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...

The script is a simple calculator to obtain numbers of Fibonacci, Tribonacci or Tetranacci Sequence. The script contain calculations for constants (up to 16 digits) that could be used as one of the sequence's number. The Calculator has 3 modes. Users can define the numbers to initialize the sequence in the options:  - The Fibonacci Sequence is the series of...

The previously proposed sequential filter aimed to filter variations lower than a certain period, this allowed to remove noisy variations and retain only the closing price values that occurred after a consecutive up/down, however because of the noisy nature of the closing price large filtering was impossible, in order to tackle to this problem the same indicator...

A moving average that weighted with Farey fractions. It matches a standard linear weighted average almost one-to-one. Why? Because both averages have strictly monotonic weighting sequences and assign a higher weight to latests data. So, Farey weights are just scaled to linear ones. Instead of specifing period you specify an order of Farey sequence. To learn more...

counts N of sequences, N of bars, N of same open/close value, and N of sequences from 1 -> 10+ bar sequences in a direction up/down.

EXPERIMENTAL: just some experimentation to check results, putting it out there. :P odds of the next bar being up or down bar.
