How to Train an MLP Using Markov Chain Features in MQL5

How to Train an MLP Using Markov Chain Features in MQL5

The article describes the two-level MarkovMLPOscillator indicator: a three-state Markov chain uses historical data to construct a transition matrix and generate 15 probabilistic features for each bar, and an MLP is trained on these features to predict price direction at a specified forecast horizon. The article covers feature generation, the validation procedure using a holdout set, and parameter settings. The result is an interpretable oscillator with a color histogram, a smoothed signal, and a display of the current transition matrix.

This part finishes the geometry layer: arcs use a sagitta‑based angular step tied to the pixel tolerance, so segment counts are computed, not guessed. The path gains ArcTo, AddCircle, AddEllipse and AddRoundRect with per‑corner radii, enabling common UI shapes such as tabs, pills, badges, rings, gauges and donut wedges.

Optimal Trade Exit in MQL5: Longstaff-Schwartz Least-Squares Monte Carlo for Continuation-Value Estimation

This article models position exits as an American option and implements the Longstaff–Schwartz least‑squares Monte Carlo in native MQL5. The engine calibrates drift and volatility from recent returns, simulates forward price paths, and uses backward induction to compare immediate exercise to continuation. It integrates into an EA with hard time and price backstops and a live indicator, and is tested on four symbol/timeframe combinations with mixed, reproducible Strategy Tester results.

Prop-firm accounts operate under a second rulebook that MetaTrader 5 does not model. This first part builds the observation layer: a per-pass frozen account snapshot read by every rule, a verdict record that reports without acting, explicit enable flags in the profile, and a session clock aligned to the firm's reset time. The result is a reproducible pass that prevents cascading effects and prepares the ground for safe decisions in Part 2.

Market Simulation: First Steps with SQL in MQL5 (III)

In the previous article, we looked at an example of implementing a class in MQL5 to provide basic support. Its purpose is specifically to allow SQL code to be stored in a separate script file. This way, we won't need to write the same SQL statements as string literals in the MQL5 source code. Although this solution is functional, there are some aspects of it that we can and should improve.

Market Simulation: First Steps with SQL in MQL5 (II)

Although many people believe that we can easily embed SQL code into other code, this is usually not the case. The reason is that the SQL code is included in the executable as a string. Embedding SQL code as a string, while not a problem for small snippets, can ultimately cause us quite a few headaches.
