Building a Moving Average Crossover Expert Advisor with Risk Controls

Summary

This tutorial outlines a two-moving-average crossover expert advisor. It exposes configurable fast and slow periods, position size, minimum equity, slippage, and fixed take-profit and stop-loss distances. Initialization checks that the parameter values are valid and that the requested trade volume meets the instrument’s minimum. On each market tick, the advisor checks equity, detects a new candle, reads the moving-average signal, submits a buy or sell transaction, and sets protective exit levels for matching open orders.

The material explains the program flow and shows how the stop and target levels are calculated relative to each order’s entry price. It is an implementation example rather than a tested trading system: it provides no backtest, performance evidence, parameter rationale, or market-specific evaluation. The described crossover rule may lag price changes, and the fixed pip distances and lot size do not account for changing volatility or portfolio-level exposure. The tutorial therefore teaches basic automated strategy structure and order management, but it does not establish that the strategy is profitable or suitable for live use.

Key ideas

• The example generates trade signals from fast and slow moving-average crossings.
• Initialization validates strategy inputs and checks the instrument’s minimum trade volume.
• The tick handler evaluates equity, new-candle status, signals, transactions, and protective exits.
• Take-profit and stop-loss prices are set relative to each order’s opening price.
• The document supplies no backtest or evidence that the crossover strategy is profitable.
