Articles on the MQL5 programming and use of trading robots
Expert Advisors created for the MetaTrader platform perform a variety of functions implemented by their developers. Trading robots can track financial symbols 24 hours a day, copy deals, create and send reports, analyze news and even provide specific custom graphical interface.
The articles describe programming techniques, mathematical ideas for data processing, tips on creating and ordering of trading robots.

MQL5 Wizard Techniques you should know (Part 94): Using Reservoir Sampling and Linear Regression in a Custom Trailing Stop Class
For this article we rotate to a custom MQL5 Wizard class implementation that explores Trailing Stops. Our custom class is ‘CTrailingReservoirLinReg’ that we derive by combining the Reservoir Sampling algorithm with a Linear Regression network. As has been the case throughout these series, this formulation is testable with MQL5 Wizard Assembled Expert Advisors that can be tuned with various entry signals and money management classes.
MQL5 Wizard Techniques you should know (Part 96): Using Wavelet Thresholding and LSTM Network in a Custom Money Management Class
In this article we consider a custom MQL5 Wizard class that processes Money Management. Our custom class is labelled ‘CMoneyWaveletLSTM’, and is developed by combining the Wavelet Thresholding algorithm with an LSTM network. As has been the case throughout these series, the developed model is testable with MQL5 Wizard-Assembled Expert Advisors that can be tuned with different trailing stops and entry Signals classes. We maintain our entry Signal, as in past articles as the built-in 'Envelopes' class and the RSI class.
Automating Classic Market Methods in MQL5 (Part 5): The Original Turtle Trading Rules
This article builds a complete MQL5 Expert Advisor that implements the original Turtle Trading rules from Curtis Faith. It covers both systems: 20/55-day breakouts, the System 1 skip rule, N (Wilder ATR) for volatility-adjusted sizing, a four‑unit pyramid with N/2 adds, a unified 2N stop, and 10/20-day exits. You will get compilable code, implementation details, and a backtesting procedure on EURUSD.
Formulating Dynamic Multi-Pair EA (Part 10): Asymmetric Stop-Loss Logic Based on Pair-Specific Volatility Signatures
The EA learns each symbol's volatility profile before trading by processing 1000 bars and summarizing candle ranges, bodies and wicks, noise ratio, trend runs, pullback size, and true‑range dispersion. A classifier assigns regime and structure labels per pair. The stop‑loss optimizer maps those labels to a symbol‑specific ATR multiplier, and the risk module sizes lots to maintain constant percentage risk.
Trading Options Without Options (Part 3): Complex Option Strategies
The article discusses flat (non-directional) and trend-following (directional) option strategies and their implementation in MQL5. The EA described in the previous article is updated. The display of option levels has been added. Now it is time to examine the strategies used by options traders in practice and put them into action.
