MQL5 Algo Trading community — forex forum for traders and developers

Algo-trading is tough. If you’ve been at it since the early 2000s like some of us, you know what I mean. We all came for the same thing: the “money-making bomb” -- one system -- switch it on -- forget the day job. Then we spent years trying to crack the price. One by one, had to admit there is no

Hello traders, I have been working on algorithmic strategies for XAUUSD (M15 timeframe), and one of the biggest challenges I face is controlling drawdown while maintaining solid profitability. In your experience: - What risk management techniques work best for gold? - Do you prefer fixed lot or

I was testing a daily loss lock in the Strategy Tester (100,000 account, 5% daily limit = 5,000, lock set at 90% of the limit). With "1 minute OHLC" the lock fired late: the day closed at 105% of the limit. With "Every tick based on real ticks" it locked at 90.0% (−4,501), exactly as designed. The

We run a small MT5 stack with a 1 % daily loss cap. It had been in place for months and we trusted it. Replaying our own history, a day where every stop gaps at its instrument’s 99th percentile reaches 13.84 % of equity . Not 1 %. The cause is simple once you see it: the limit counts the stop, not

I run an LLM-driven intraday scalper on MT5 (demo). Over 60 closed trades it lost $212, and commission alone was 40% of that loss. Before asking "how do I make it profitable", I spent two weeks trying to establish whether it has any directional edge at all. It does not — and I want a sanity check

How do you measure the real impact of economic news on an EA? I've been researching how automated trading systems behave around economic releases, and I've noticed that simply classifying events as Low, Medium or High impact doesn't tell the whole story. Two High-impact events can produce completely

I've been thinking about market regimes lately and I'm starting to question how we normally build EAs. Most strategies are basically built around the assumption that the market behaviour we see in the backtest will continue to exist in the future. But we all know that isn't always the case. A trend

Over the years, I’ve tested and observed many Expert Advisors, especially on XAUUSD. And there’s something that keeps repeating itself again and again. Most EAs that show amazing backtests on gold rely on some form of martingale or grid logic. At first glance, everything looks perfect: high win
