MQL5 From Scratch: How to Code Your First Expert Advisor

Automating a trading strategy is one of the biggest milestones in a trader’s development. Instead of manually clicking buy and sell, you let a program execute your rules automatically, without fear, greed, or fatigue. In the MetaTrader 5 ecosystem this program is called an Expert Advisor (EA), and it is written in the MQL5 programming language. This article walks you step by step through coding your first Expert Advisor in MQL5. You will learn: What MQL5 and Expert Advisors are How an EA is structured How to use built-in indicators (Moving Averages) How to open and manage trades from code…

Perfect Forex Trading System in MetaTrader 5 (MQL): What Elements Should It Include?

Designing a durable MT5 system is not about a clever entry. It’s a production problem that spans economics (why it works), statistics (proof it works), market microstructure (costs & execution), and software engineering (so it keeps working). Below is a practitioner’s blueprint—concepts, guardrails, and concrete MQL5 patterns—to build a system that survives regime shifts, costs, and live operations. 1) Economic Thesis → Strategy Design Non-negotiable: every rule must trace back to an economic hypothesis or a repeatable behavioral pattern. Macro/structural edges: carry (rate differentials), terms-of-trade proxies (commodity FX), policy path repricing (OIS/expectations), risk-on/off cycles. Behavioral/technical edges: trend persistence (session flows),…

Architecting the Ideal Forex Trading System: A Technical Guide

Designing a durable Forex trading bot is equal parts economics, statistics, market microstructure, and software engineering—and it fails if any one of those pillars is weak. “Durable” means the system remains profitable and controllable across regime shifts (risk-on/off, volatility spikes, liquidity droughts), survives realistic costs (spreads, swaps, slippage, last-look), and resists model drift and data pathologies. It also means decisions are explainable, risks are bounded, and operations are resilient to outages and bad ticks. This article extends the prior framework by shifting from “what to build” to “how it survives.” We’ll translate economic hypotheses into testable signals, enforce honest validation…
