MQL5 Wizard Techniques you should know (Part 40): Parabolic SAR MetaTrader 5를 위하여
The Parabolic Stop-and-Reversal (SAR) is an indicator for trend confirmation and trend termination points. Because it is a laggard in identifying trends its primary purpose has been in positioning trailing stop losses on open positions. We, however, explore if indeed it could be used as an Expert
MQL5 Wizard Techniques you should know (Part 39): Relative Strength Index MetaTrader 5를 위하여
The RSI is a popular momentum oscillator that measures pace and size of a security’s recent price change to evaluate over-and-under valued situations in the security’s price. These insights in speed and magnitude are key in defining reversal points. We put this oscillator to work in another custom
MQL5 Wizard Techniques you should know (Part 38): Bollinger Bands MetaTrader 5를 위하여
Bollinger Bands are a very common Envelope Indicator used by a lot of traders to manually place and close trades. We examine this indicator by considering as many of the different possible signals it does generate, and see how they could be put to use in a wizard assembled Expert Advisor
MQL5 Wizard Techniques you should know (Part 37): Gaussian Process Regression with Linear and Matern Kernels MetaTrader 5를 위하여
Linear Kernels are the simplest matrix of its kind used in machine learning for linear regression and support vector machines. The Matérn kernel on the other hand is a more versatile version of the Radial Basis Function we looked at in an earlier article, and it is adept at mapping functions that
MQL5 Wizard Techniques you should know (Part 36): Q-Learning with Markov Chains MetaTrader 5를 위하여
Reinforcement Learning is one of the three main tenets in machine learning, alongside supervised learning and unsupervised learning. It is therefore concerned with optimal control, or learning the best long-term policy that will best suit the objective function. It is with this back-drop, that we
MQL5 Wizard Techniques you should know (Part 35): Support Vector Regression MetaTrader 5를 위하여
Support Vector Regression is an idealistic way of finding a function or ‘hyper-plane’ that best describes the relationship between two sets of data. We attempt to exploit this in time series forecasting within custom classes of the MQL5 wizard
MQL5 Wizard Techniques you should know (Part 34): Price-Embedding with an Unconventional RBM MetaTrader 5를 위하여
Restricted Boltzmann Machines are a form of neural network that was developed in the mid 1980s at a time when compute resources were prohibitively expensive. At its onset, it relied on Gibbs Sampling and Contrastive Divergence in order to reduce dimensionality or capture the hidden
MQL5 Wizard Techniques you should know (Part 33): Gaussian Process Kernels MetaTrader 5를 위하여
Gaussian Process Kernels are the covariance function of the Normal Distribution that could play a role in forecasting. We explore this unique algorithm in a custom signal class of MQL5 to see if it could be put to use as a prime entry and exit signal
MQL5 Wizard Techniques you should know (Part 32): Regularization MetaTrader 5를 위하여
Regularization is a form of penalizing the loss function in proportion to the discrete weighting applied throughout the various layers of a neural network. We look at the significance, for some of the various regularization forms, this can have in test runs with a wizard assembled Expert Advisor
MQL5 Wizard Techniques you should know (Part 31): Selecting the Loss Function MetaTrader 5를 위하여
Loss Function is the key metric of machine learning algorithms that provides feedback to the training process by quantifying how well a given set of parameters are performing when compared to their intended target. We explore the various formats of this function in an MQL5 custom wizard class
