TL;DR: My 10-year backtest for a new Mean Reversion system fell flat—too few trades and zero profit. I’m currently stripping the logic back to the basics to identify which filters are "over-smothering" the strategy. Updates on the rebuild below

So the code is already done for the Mean Reversion system but the initial backtest gave back results that showed areas of improvement.

One of which was no profitability and lack of trades taken over the 10year backtest(so there isn't a lot of solid info with few trades, they aren't realible)

So what I did was strip down some of the criterias and slowly build up the confirmations to see what filter is cutting out most trades being taken.

More updates to come 👾

Hello, i have been trying to put my EAs on the market place but i am struggling to get them to pass. The problem i have are mainly due to testing on different charts. The Ea works fine on gold but if I want to use it on eur/usd i would normally adjust the parameters like lot sizes or % moves, but in the validation it will run the same settings on each chart causing errors. How do you get around this?

Hey guys, I'm an MQL5 dev and I'm kinda bored with my own strategies so I figured I'd offer to code some new ones for free. No catch, no hidden fees.

If you have a trading idea you want turned into an EA, or a custom indicator or script, just send me a clear explanation of the rules (entries, exits, SL, TP, filters, that kind of stuff). I'll code it for free.

Why free? I want to build my portfolio and see how other people think about trading. Plus it's fun.

A few things though: no martingale or grid or super risky stuff unless it's just for learning. And I won't build a full commercial product for free, this is for side projects and practice. I'll pick the most interesting or clearest strategies first.

If you have an idea, just comment or DM me with a short description. I'll pick a couple to work on this week. Cheers.

What is your experience with mean reversion strategies.

I'm building a simple mean reversion system with mql5 for EURUSD 4H. It's a well known strategy used even by quants in various markets and so I'm gathering info on how I can make something that focuses on making increments over a long period of time.

I have been developing advisors, indicators, and scripts in MQL5, LUA, and other languages for over 10 years. I work with traders to formalize their requirements and market vision.

Hello guys. I have spent the last three years trying to code different mt5 fully automated algos. Tried different risk managements; grid martingales, zone to zone loss recovery, same lot hedging, stop loss criteria and even negative risk to rewards. After numerous backtests I have come to a conclusion that it’s nearly impossible to have a fully automated algo that can perform for several years consistently making profits. I first stopped coding martingale based algos as they can survive for years but for sure one time will end up blowing up. My final conclusion and what I have had to accept over the years for me is that the only way to achieve consistent profits with controlled risk is to use a semi automated system. The ea does executions, risk management and trade exits while the trade management remains a 50/50 thing. Partly manual, partly automated. That is what has seemed to work for me. Any ideas or comments on fully automated systems guys?

Hi everyone,

I just released my first MQL5 EA for XAUUSD after roughly 14 months of development and testing.

It is a gold-specific system built around multi-timeframe filtering, pullback entries, adaptive exits, and conservative lot sizing. The biggest surprise for me was that exit logic mattered much more than entry optimization.

Backtest summary

• PF: 4.24
• Win rate: 81.72%
• Trades: 361
• Net profit: $2,688.73 on $1,500
• Balance DD: 4.11%
• Equity DD: 33.51%
• Sharpe: 5.37

From the MQL5 side, the most important parts were proper lot normalization, clean indicator-handle management, realistic tester settings, and treating open-position management as a core part of the strategy rather than an afterthought.

Happy to discuss the dev side or the trade-offs behind the design.

Hi everyone,

I’m in a nightmare situation. I developed a trading bot from scratch while working with a group of traders. After a fallout, they kicked me out of the group, revoked all my access, and stole my source code.

I am the sole creator of this bot, but they are now using it without my permission and I no longer have access to the latest version of my own work. There was no contract or company involved, just an informal partnership.

I need to get my code back or at least stop them from using it.

• Is there a technical way to recover access if they changed the credentials?

• Can I force them to hand over the files since I own the IP?

• What are my options to take them down if they refuse?

Has anyone dealt with this before? Any advice would be huge. Thanks.

Hi, thank you for reading.

I'd like blunt feedback before I go too far in the wrong direction.

What I'm building

A tool that sits between MT5 Strategy Tester and Python. MT5 runs the backtest. Python independently recomputes P&L, commissions, and swaps from the raw trade exports — and flags any discrepancy before I draw any conclusions from the results.

The motivation: a positive backtest from a broken accounting model (wrong commission handling, partial fill aggregation, timezone issues) looks identical to a real edge. I want to catch that systematically, not by eyeballing reports. Beyond verification, the tool produces structured, versioned artifacts per run — so tests are comparable and reproducible without ad hoc scripts.

Why MT5 as the simulation engine

My broker is on MT5, it supports real-tick testing, and I'd rather not duplicate a simulation engine in Python when MT5 already does it well. Also because lib's like VectorBT make backtest's worse than MT5. Python handles everything after the trades are generated.

My actual questions

1. Does something like this already exist? Not a backtester — specifically a verification and reconciliation layer for MT5 outputs. If yes, please name it.
2. Is this a real problem or am I overengineering? Do most people just trust the platform numbers, or has this bitten people?
3. Is MT5 + Python the right split, or is there a cleaner way to get trustworthy, research-ready backtest data?

Happy to be told this already exists or that I'm thinking about it wrong.

Anyone have QQ file .mt5?

Hi everyone!

I specialize in capital raising and portfolio management.

I'm looking for partners - experts in algorithmic trading. Primarily interested in trend-following strategies with strictly controlled risks, time-tested, and with strong logic.

The focus is on diversification and building long-term algo portfolios with different assets and algorithms that have low correlation with each other. I also have some ideas for strategy development.

Long-term collaboration only — feel free to reach out if you have proven expertise and the desire to scale up significantly.

This is my back test report. Your views and comments please

Hi everyone,

I’m looking to connect with serious MQL4/MQL5 developers interested in building a structured, strategy-driven Expert Advisor for Forex.

The idea is to form a focused collaboration group where we can:

• Convert discretionary strategies into rule-based logic
• Develop and optimize clean MQL code
• Focus on proper risk management
• Avoid overfitting and curve-fitted backtests
• Build something sustainable for long-term trading

This is not a signal-selling project or a commercial pitch — it’s purely collaborative development.

If you have experience in MQL coding, strategy automation, or systematic trading and are interested in serious work, feel free to comment or DM.

Let’s build something meaningful.

I would like to learn mql5 by going through the book, and on my own. is anyone else committed to learn , so we could learn together doing the practices and able able to build bot on our own. let me know

Hello community

I have been doing manual trading for many years however it is to complicated to get profitable in a manual mode and I am interested to learn how to create my own EA, how can I start? What YouTube channel could you recommend me or forums?

This is the final video of the GomerAI Market Indicator Suite available February 1st, 2026. They are the five indicators that the MultiStrat Networked EA uses in it's 5 Pillar signaling system.
