I have been running MT5 on my Kali Linux system for a while and recently purchased a cheap computer.

Got Kali up and running on the

I've been running several EAs together on the same account instead of one single strategy, mainly to smooth the equity curve, but it's forcing me to rethink risk management completely.

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

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

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'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.

How do you measure the real impact of economic news on an EA?

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

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

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

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

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

Hello everyone, I’ve seen Expert Advisors that have managed to run profitably for years. Even a few martingale strategies have kept going much longer than expected. But sooner or later, most seem to blow the account or simply stop performing the way they once did. It makes me wonder what it really
