It is so easy to prove that many EAs (I really mean many - contact me for the names) have ways to cheat backtests . Most of them cheat a simple backtest fully, some of them cheat a backtests moderatly to heavily. A simple statistical analysis can reveal if the EA is cheating as at a certain date the

What in the hell happened here? Clearly a glitch on Metaquotes end... Can this be reversed? Now my journal across all my Metaquotes terminals are being spammed with these old ticks every 1ms filling my journal logs up massively every second. This was a Metaquotes demo account

Hello, Following an MT5 update on 28 October 2026, my Strategy Tester has stopped working correctly. Platform: MetaTrader 5, Build 6290 (27 October 2026) Server: MetaQuotes-Demo Symbol: EURUSD, M15 Problem: Strategy Tester repeatedly fails to synchronise historical data, despite historical bars

Summary: Since some build between 5833 and 6140, the Strategy Tester returns real_volume = 1 for bars of any timeframe other than the tested chart timeframe. tick_volume is still correct, and so is history before the test start date. On the chart timeframe itself, real volume is correct. Build 5833

What kind of vps do you use? Maybe some cheap and reliable advice for 5-10 terminals

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

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

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

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

Good day dear forum members. After reading the forum a bit, I came across several threads on arbitrage and pair trading . Judging by the threads, some are interested and some are trying it. I used to dabble in this topic a long time ago, but my knowledge was not enough. Now I am a complete mess in

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

Hi Here is the code I use for my money management. - Actually it shouldn't be called MM, as it is only calculates how many lots can I buy so that when I hit my stop loss I only loss a certain percentage of my account.

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

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

Hi everyone, there were a few threads here lately about backtest vs live. Most ask why the two differ. I'd like to ask something a bit different: how do you notice it early enough? What I do with my EAs is pretty simple. I run the backtest over the same weeks as the live trades, on my broker's

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

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

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.

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

I’m currently coding an MT5 EA and I’d like to add an image/logo directly onto the chart (not just text or lines). I’ve been experimenting with OBJ_BITMAP and OBJ_BITMAP_LABEL, but I’m not fully sure how to properly load and display a custom image in the EA. Has anyone here done this before?🤷‍♂️

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

Why is it that MT5 has a white flicker when you change timeframes while MT4 operates smoothly? Is it because the charts in MT5 are not preserved and are rebuilt every timeframe switch?
