barmenteros FX is an independent team of algorithmic trading developers based in Marbella, Spain. We build, fix and migrate Expert Advisors, indicators and machine learning systems for traders and firms: on MetaTrader since 2011, and also on NinjaTrader, cTrader, TradeStation, MultiCharts and TradingView. Every project gets a fixed-price quote before work starts, every EA is tested against the edge cases that break live systems, and you receive the compiled files and the full source code.

Small, well-defined jobs are welcome too: fixes, indicators, simple EAs.

"SL updated" Is Not a Result: Logging the Broker's Answer to OrderModify() in MQL4

3 11月 2026, 11:20
We fixed a trailing EA that printed "SL updated" for weeks while its stop loss never moved. Nothing in the code was exotic. The EA computed a new stop, called OrderModify(), updated its own record of the stop, and printed the line. It never read what the call returned...

3,225 requests since 2012: what traders ask us to build, and where the simple ones fail

27 10月 2026, 13:26
We went back over our own request forms since 2012 and sorted them into 33 needs. After removing copies and anything under 50 characters of description, that left 3,225 requests from 2,102 traders...

Alert(), SendMail(), SendNotification(), PlaySound(): One Helper for MT4's Four Alert Channels

21 10月 2026, 10:22
MT4 gives an indicator or an Expert Advisor four ways to tell the trader that something happened: a pop-up alert, an email, a push notification and a plain sound. Each one is a single function call...

Closed Bar or Forming Bar: Which Candle Your EA's Signals Should Read

28 9月 2026, 19:11
Every indicator-based Expert Advisor has to decide which candle it reads: the one that is still forming, or the last one that closed. The same moving-average crossover or RSI threshold behaves differently depending on the answer...

MT4 End-of-Life Now Comes With Dates — and Why "Just Recompile It" Fails on Netting Accounts

Why a Converted MQL4 EA Compiles Clean and Still Trades Differently

22 8月 2026, 18:44
A converted Expert Advisor that compiles without a single error is not evidence that the conversion worked. The characteristic MT4 to MT5 failure does not produce anything wrong to find — it produces an absence, something that should have happened and didn't...

MT4 to MT5: four migration bugs that survive a clean recompile

11 8月 2026, 22:07
A clean recompile is where an MT4-to-MT5 migration starts, not where it ends. The functions rename, the errors clear, the Strategy Tester runs — and four architecture differences sit underneath, none of which throws an error...

CTrade::PositionClose() — The Return Value Contract and What It Costs in Production

10 8月 2026, 21:26
If you are migrating from MQL4 or debugging a position management bug you cannot reproduce in Strategy Tester, read this before changing anything else. What the Documentation Actually Says The MQL5 reference for CTrade::PositionClose() is technically accurate. Both overloads are listed...

Entry Latency Is a Solved Problem. Position State After a Restart Is Not.

5 8月 2026, 15:01
There is a conversation that repeats often enough to be worth writing down. A trader has traded a setup manually for months, decides to automate it, and frames the project as "turn my rules into an EA." The entry logic gets written in an afternoon...

What MT4 Programmers Do Before Writing a Line of Code

4 8月 2026, 22:00
Every EA project starts with a brief. The brief describes entry conditions, exit logic, position sizing, and timeframe. It is usually thorough on paper. In practice, it is almost never complete...

EA State Loss on Restart: What MetaTrader Erases and How to Persist It

3 8月 2026, 20:46
The Failure Pattern Most EA reliability discussions focus on broker edge cases, slippage, and backtest-to-live gaps. The restart failure is quieter — and it repeats on every restart. The pattern: an EA runs correctly for months on a VPS...

Why AccountBalance() Is Wrong for Multi-Position EAs (and How to Fix It)

31 7月 2026, 18:11
The Problem Picture an EA rescue brief like this: excellent single-trade backtest results, inconsistent live performance during periods when two or more positions run simultaneously. The root cause can be a single function call — AccountBalance() in the lot-size function...

Which Prop Firm Clauses Your EA Can Actually Check at Runtime

29 7月 2026, 14:18
Permission to run an Expert Advisor is not what disqualifies automated prop-firm accounts. Automation permission is not where firms compete — they differentiate on payout splits, drawdown limits, and challenge fees...

Why Your Portfolio EA Is Acting on Orders It Didn't Place

28 7月 2026, 13:31
The Silent Failure Mode Running two or more expert advisors on the same MetaTrader account exposes a structural gap that single-EA backtesting never reveals. The platform logs no warning when one EA modifies or closes an order it doesn't own...

What Actually Belongs in a DRL Trading Agent's Observation Vector

26 7月 2026, 21:56
A PPO agent trained for two million steps on EURUSD 15-minute data with flat reward curves across all five seeds is not an optimizer problem. Switching to SAC will not fix it. Changing the learning rate will not fix it...

Choosing a DRL Algorithm for MetaTrader: Why Drawdown Beats Return

25 7月 2026, 12:51
DRL algorithm comparisons often headline annualized return. If you plan to deploy the agent on a live MetaTrader account, that is the wrong column to sort on. Here is a benchmark that makes the point concrete...

Why Your DRL Agent Trades Fine in Backtest and Falls Apart Live: The Bridge Parity Problem

24 7月 2026, 15:25
If you have trained a deep reinforcement learning agent in Python and tried to run it against a live MT5 terminal, you may have seen this: the agent converges cleanly, the backtest Sharpe looks good, and then on a paper account it behaves like it never trained. No error, no warning...

Prop Firm EA Compliance: Four Infrastructure Gaps That Cause Challenge Disqualification

23 7月 2026, 21:27
Consider a Phase 1 challenge EA that is disqualified on day 9. The strategy is profitable — positive P&L at the point of disqualification. The journal tells the story: trades are opening after the daily loss limit has already been breached...

The three passes we make over an Expert Advisor before we look at the strategy

22 7月 2026, 14:44
A clean compile tells you the syntax is valid. That is the whole of its claim. It does not tell you that the correct order was selected before the close, that a rejected request was noticed, or that the Expert Advisor still knows what it holds after a terminal restart...

Diagnosing EA Performance Degradation: When the Broker Changes the Spread Model

21 7月 2026, 14:31
The Pattern A trader runs an EA profitably for months or years. No code changes. No settings modified. The equity curve starts bleeding. The trader backtests with the old spreads — still shows good results. The trader re-optimizes — makes it worse...
