Hello everyone, I’d like to share some backtest observations and findings from a personal algorithmic trading project I've been researching.

Hello, I am preparing a multi-symbol MT5 Expert Advisor that trades XAUUSD and BTCUSD. It works in local Strategy Tester tests on a broker providing both instruments.

I am investigating a Strategy Tester case where GBPAUD stops receiving current quote updates after other symbols have been initialized. A diagnostic EA that sends no orders reproduces it. I would appreciate advice on the initialization and synchronization sequence; I have not established whether

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

I'm running macOS Catalina 10.15.8 on an Intel MacBook Pro (Mid-2012). The official MT5 installer completes successfully, but MT5 won't launch. Wine reports Symbol not found: _pthread_cpu_number_np , and says ntdll.so was built for Mac OS X 11.0. Is there a Catalina-compatible installer

How many of you have lost a prop firm challenge because of the loss limits (daily or maximum), and not because of the strategy? And what would have helped you the most to pass? A clearer rule from the firm, an alert before reaching the limit, a fixed daily routine, smaller position sizes, or

I traded this EA and backtested it normally. Why is this error appearing when I upload it to the store? Please advise me

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

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

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

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

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

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

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

Hello everyone, I wanted to share some lessons learned about parameter optimization, hoping to get your feedback and maybe some ideas to improve. 1. Walk- forward optimization beats simple single-period optimization. A strategy that looks great on one year of history often breaks on the next six

Hello MetaQuotes team, I am trying to establish the provenance of an EX5 file loaded by a local MetaTrader 5 Strategy Tester agent. In one run, the agent journal reported “expert file added ... 239101 bytes loaded,” while the frozen local EX5 file measured 239012 bytes. I do not know whether these

I have discussed a couple of times in threads about EAs and if they have any real edge or not. But what is really considered an edge? Is it a combination of indicators that on historical prices of a specific market can predict the direction of price most of the time? Will it suffice to have a

I wanted to know whether one of the new pre-trained time-series models can run inside MetaTrader 5 itself, without Python, DLLs or WebRequest, so that it also works in the Strategy Tester. It can. These are my notes on IBM's Granite TTM-R2 (Tiny Time Mixers, Apache-2.0), with the numbers I measured

Any EA that works with fixed session times (Tokyo fixing, London open, New York close) needs the broker's GMT offset, the difference between server time and UTC. Live, TimeTradeServer() - TimeGMT() gives it. In the Strategy Tester it does not: the documentation says that during testing TimeGMT() is

Running 2 EAs on MT5 via VPS. Recently had one go quiet for about 3 days — no crash, no errors in Experts or Journal, smiley face still there, terminal connected. It just stopped taking trades. I only found out because I manually check the accounts every few days. Could easily have been longer

After a lot of bought EAs, prop challenges and backtests that looked great, I ended up with a short checklist I now go through before I pay for anything. Backtests weren't the problem. They just never told the whole story. Here's my list. Curious what you'd add or disagree with. 1. Deposits dressed

Hi, i'm intended to create an EA with AI Assistant (MQL5 model), but before there are somethings i wanna know first: Can I build complex EAs with MQL5 Lite, or does its capability depend on the prompts I give it? Can I continue working on my prompt in the same chat room on another day once I've

Hi all, In early October 2026, I went through the product pages and public signal track records of ten of the best-selling scalping and martingale-type EAs on the MQL5 Market, and checked every figure twice. I'm not naming any sellers — patterns matter more than people. Here is what kept repeating

Hello MetaQuotes Support, We need to determine whether an MQL5 Expert Advisor can enforce a strict 14,400-second wall-clock deadline when an in-progress file operation does not return. Could you please clarify: Are FileOpen, FileWriteString, FileFlush, FileClose, FileMove, FileCopy, FileReadArray
