Check out the new article: RSI Divergence Grid Expert Advisor with Risk Manager in MQL5.

A simple grid trading strategy becomes a resilient system thanks to three components: an entry filter based on RSI divergence, a strict limit on the number of grid levels, and an independent risk manager that monitors equity on every tick and blocks trading when the daily limit or maximum drawdown is reached. The article examines the mathematics behind the classic martingale trap, the implementation of pivot point and RSI divergence detection in MQL5, the complete code for the CRiskManager class with protection against floating losses, and the architecture of the grid itself, with TP based on the weighted average entry price.

Grid trading is one of the first strategies a beginner algorithmic trader learns. The logic is appealing because of its simplicity: the price is always moving in one direction or another, so if you open orders at fixed intervals on both sides, sooner or later some of them will close at a profit. The problem is that this very "sooner or later" wipes out your account faster than you might think.

A classic grid system without a filter or risk manager is a Martingale trap in disguise. It performs well in backtesting until the first strong trend, and then wipes out the account in a matter of hours. Experienced traders know this. But most beginners learn this lesson the hard way — at their own expense.

This article shows how to build a more resilient grid. Three components transform a simple grid Expert Advisor into a robust system:

  1. RSI divergence-based entry filter: the grid opens only when there is a statistically valid reversal signal, not at any random moment;
  2. built-in risk manager: it checks equity against the limits on every tick and immediately blocks trading when equity approaches those limits;
  3. strict limit on the number of grid levels: the Expert Advisor cannot open more than a specified number of orders in a single grid, which in itself limits the maximum loss to a calculable amount.

An interesting article, thank you very much. As for the trading approach – I’ll test that out in live trading too… I might add or remove a few things – since I’ve got the foundation in place… I’ll set up a stop-loss calculation using Magic, linked to the expert advisor. I might also tweak or change a few things for the account’s netting type... The trading approach is fine. Thanks. I’m looking into it...
The chart’s performance is extremely sub-optimal. Testing on every tick whilst viewing the chart is simply a nightmare. The author has, in my view, just put this together for the sake of the text.
