Why a hardcoded account-number check isn't license protection

7 July 2026, 11:44
The check that feels like a lock Most of us started here. You want to stop your EA from running on accounts that didn't pay, so you drop something like this near the top of OnInit() : int OnInit() { long allowed = 12345678; // the buyer's MT account if(AccountInfoInteger(ACCOUNT_LOGIN...

Why "simple" MQL4/MQL5 requests expand: repainting removal, panels, and the hidden decision set

2 July 2026, 22:20
If you develop for clients — or you are a trader commissioning tools — you have met this request: "Remove the repainting from my indicator. Should be quick, right?" One line, priced by the requester at one day of work...

Your MT4 EA Compiles on MT5. That's the Part That Fools You.

1 July 2026, 14:40
There's a moment in every MT4-to-MT5 move where the terminal reports "0 errors" and it feels like the job is done. It isn't. A clean compile only tells you the syntax converted...

Three Silent Failures in MT4 to MT5 Migration (And the Audit That Catches Them)

30 June 2026, 21:37
The standard migration advice goes like this: rename the file, resolve the compile errors — most of which are renamed functions — and run the backtester. If the equity curve looks similar, you are done...

Five Symbol-Specific Assumptions That Silently Break EAs on Non-EURUSD Instruments

29 June 2026, 22:53
Most EAs I debug for cross-symbol failures share the same five hardcoded assumptions. They are all correct on EURUSD and all wrong on everything else. Here is what breaks, why, and the runtime queries that fix each one...

Three Ways Your Session Filter Gets Time Wrong (And the Permanent Fix)

28 June 2026, 18:08

Five Structural Failures I Find in Most "Working" EAs

27 June 2026, 19:24
After 14 years of reviewing and rescuing Expert Advisors — across 30+ code reviews over the past three years alone — the structural problems repeat with remarkable consistency. This is not about strategy logic. The strategies are often fine...

The Production Layer Your Backtest Never Tests: OrderSend Retries and Restart-Safe State

26 June 2026, 10:24
A clean backtest proves your entry and exit rules. It does not prove your EA will survive a live night. Those are two different things, and the gap between them is where most EAs quietly fail at 2am. The backtester feeds your code a tidy, sequential stream of ticks. Every order fills...

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

11 June 2026, 22:14
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

3 June 2026, 10:07
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...

What MT4 Programmers Do Before Writing a Line of Code

28 May 2026, 11:51
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...

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

20 May 2026, 07:54
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...

Three Factors That Determine Whether Your EA Needs Fixing or Rebuilding

15 May 2026, 10:12
Whether a struggling EA deserves targeted optimization or a full rebuild comes down to three structural factors: code structure quality, strategy logic validity, and state management architecture. I evaluate this regularly for clients, and the answer is never obvious from the outside...
