Netting & Hedging Accounts
MetaTrader 5 supports both account types, and position logic has to match. Expert Advisors are written for the one you trade — or for both.

Service overview
MQL5 Code Written for How MetaTrader 5 Works
New Expert Advisors and indicators, existing MQL5 code, and MQL4 code that has to move.
Nordman Algorithms writes MQL5 code for traders, prop traders, signal providers and software vendors on MetaTrader 5. Our MQL5 developers work from trading rules, a written specification or just a plain description, existing .mq5 source — and from MQL4 Expert Advisors and indicators that need to move to MetaTrader 5.
MetaTrader 5 is not MetaTrader 4 with a new name. Orders, deals and positions are separate, accounts can be netting or hedging, and the Strategy Tester runs on real ticks across several symbols at once. Every Expert Advisor, indicator and tool is written for these conditions and your broker, and checked on real ticks before it reaches your account.
The finished .mq5 source code and all rights to it are yours on delivery.

Beyond MQL4
What MQL5 Makes Possible
MetaTrader 5 capabilities that MQL4 code cannot use — and that shape how MQL5 code is built.
Real-Tick, Multi-Symbol Testing
The Strategy Tester runs on real ticks, tests several symbols in one pass and spreads optimization across local and cloud agents.
Built-In Economic Calendar
News filters read release times straight from the terminal’s own calendar, with no external feed to maintain.
Market Depth & Exchange Instruments
On exchange-connected accounts, stocks, futures and options are available, and Expert Advisors and indicators can read the order book.
Machine-Learning Models in the EA
Models trained elsewhere run inside MQL5 in ONNX format, so an Expert Advisor can use them without calling an outside service.
Custom Charts & Synthetic Symbols
Renko, range bars or the spread between two instruments can be built as a custom symbol, then charted and tested — while the Expert Advisor trades the real instrument.
Working with existing code
MQL5 Code Services
An MQL5 developer working on the Expert Advisors, indicators and scripts you already have — and on MQL4 code that needs to move to MetaTrader 5.
MQL5 Code Modification
New rules, filters, inputs and functions added to existing .mq5 source — including code written by another developer — while the parts that already work stay intact.
For example
- News filter from the economic calendar
- Multi-symbol trading from one EA
- Hedging-mode position handling
- Telegram and push alerts
MQL5 Debugging & Error Fixing
Trade requests the server rejects, position logic that breaks on netting or hedging accounts, indicators that repaint and compilation errors after MetaTrader updates — traced to the cause in the code and fixed. When tester and live results differ, we find out why, correct the code and take execution conditions into account.
For example
- Rejected trade requests
- Wrong position count on hedging accounts
- Real-tick test and live results differ
- Indicator repaints
MQL5 Code Optimization & Refactoring
Heavy calculations moved off the tick, slow multi-symbol loops rewritten, and procedural code reorganised into classes that are easier to extend and test.
For example
- Faster optimization passes
- Class-based structure
- Shared include libraries
- Fewer redundant calculations
MQL5 API & External System Integration
MQL5 connected to external systems through HTTP requests, its own socket functions, DLLs and the official MetaTrader 5 package for Python — with trained models running inside the terminal in ONNX format.
For example
- Python analytics driving an EA
- ONNX model inside an EA
- Licence check against a server
- Live data over sockets
MQL4 to MQL5 Migration & Conversion
MQL4 Expert Advisors and indicators rebuilt for MetaTrader 5’s order, deal and position model rather than translated line by line, then run side by side with the original to compare results. MQL5 logic can also be moved to NinjaScript, cTrader or Pine Script. Still working in MQL4? See MQL4 development.
For example
- MQL4 to MQL5 migration
- MT4 indicator suite to MT5
- MQL5 to NinjaScript or cTrader
- Side-by-side result check

Send a description of what you need and the .mq5 and .mqh files if there is existing code — we will review it and tell you what it would take.
Combined projects
MQL5 With Other Technologies
MetaTrader 5 offers more ways to reach beyond the terminal than MetaTrader 4. The right one depends on what the external system has to do.
Models & analysis
Python & Machine Learning
Python works with the terminal through the official MetaTrader 5 package, and trained models can run inside MQL5 in ONNX format.
Desktop & heavy logic
C# / .NET Applications
Desktop tools, demanding calculations and links to other Windows software, connected to MQL5 through a DLL.
Data & signals
REST, WebSocket & Webhooks
HTTP requests, live connections over MQL5’s own socket functions, and incoming alerts through a webhook receiver.

"Alexei is the only one who got this project done, i have tried many before him but all of them failed. a professional programmer i can rely on very mature and excellent in communication. really patient and will revise and develop the coding to satisfaction level. …"
★★★★★
"I simply can not emphasis enough appreciation I have for this top coder. My project was a custom variation to a popular strategy that required great detail and expertise from the coder. Alexei went far and beyond my expectations and delivered my project on time and on budget. If you're looking for the best, look no further. …"

"I have used Nordman Algorithms to code about a dozen MT4/MT5 Expert advisors and custom indicators I have developed over the past few years and honestly I can't recommend them enough. Each project has been delivered quickly and for a fair price. …"
FAQ
MQL5 Development Questions
Practical answers about MQL5 code, migration from MQL4 and MetaTrader 5.
Yes. Rather than translating it line by line, we rebuild the logic for MetaTrader 5’s order, deal and position model, then run both versions side by side and compare the results.
Yes. On a netting account one symbol holds a single position; on a hedging account several can be open at once. Position logic written for one type can misbehave on the other, so we write for the account you trade — or for both.
Yes. Models trained elsewhere can run inside an Expert Advisor in ONNX format, and Python can work with the terminal through the official MetaTrader 5 package. The right route depends on the model and how often it is used.
Yes. The first step is reading the existing .mq5 code to see how it is structured and what it depends on; changes are then made so that the working parts keep behaving as before.
Compiled files are not decompiled. What we can do is look at what you still have — the trading rules, input settings, screenshots or trade history — and tell you whether the Expert Advisor can be rebuilt from it. If it can, the new version comes with full MQL5 source that belongs to you.
Testing on real ticks narrows the gap, but spreads, execution and broker rules on a live account can still differ. We find the cause first, fix errors in the code, and take execution conditions into account where possible.
Yes. You receive the .mq5 source, the compiled .ex5 file, settings presets and instructions. Source code and full IP ownership are transferred on delivery.
A description of the rules or the change you need, the .mq5 and .mqh files if there is existing code, and whether your account is netting or hedging. Screenshots and settings help as well.
