MetaTrader 4 Developer — Custom MT4 Development Services

Yes. We review editable MQL4 source code, reproduce the issue, and agree the changes. Typical work includes incorrect entries, missed alerts, stop-management errors, or new trading filters. If you only have an EX4 file, we can assess a rebuild from documented rules; a compiled file is not a substitute for editable source.

Yes, when its signals can be defined and read reliably. We agree which indicator outputs trigger trades, whether signals are evaluated on a closed bar, and what happens if signals change. The EA also needs explicit exit, sizing, and order-management rules.

A trade copier reads orders and changes from a source trading account and applies them to receiving accounts. A signal copier interprets external instructions, such as Telegram messages or TradingView alerts, before placing MT4 orders. Both need agreed symbol mapping, position sizing, and duplicate-handling rules.

Yes, for accounts that support MT4 and permit the proposed automation. Tools can monitor equity, daily losses, open exposure, and trading hours, then apply agreed actions. We clarify reset times and how floating profit or loss is counted. Software controls do not guarantee compliance under every market condition or a passed evaluation.

Yes. Cross-platform conversion can work in either direction when the required data and functionality are available. MQL4 and MQL5 use different trading interfaces, so an EX4 file cannot simply be opened in MT5. We rebuild the relevant logic and compare signals and trade behaviour against agreed reference examples.

It can connect an EA to external signals, reporting, data, or licensing services using HTTP requests or a custom bridge. Broker-side Manager and Server APIs are a separate infrastructure scope requiring appropriate access. An ordinary MT4 trading login does not provide those broker-side permissions.

Yes, through a custom connection between the MT4 terminal and an external service. The bridge can exchange signals, account data, or reports while an MQL4 receiver handles terminal actions. We agree hosting, connection recovery, and permissions; Python and C# components run outside the native MQL4 program.

An MT4 developer reviews the rules, interfaces, and existing code first, then we provide a fixed quote and timeline. Testing follows the agreed examples: historical checks where suitable, plus demo-account checks for execution and integrations. MT4 WebRequest calls do not run in the Strategy Tester, so connected functions need separate testing. Delivery files and technical support are defined in the scope.

Yes. Options include account restrictions, trial expiry, activation keys, and server-based licence checks. We define how the software behaves during a connection outage or renewal. Access controls help manage distribution, but no software-protection method can promise absolute resistance to copying.
