Hiring a MetaTrader programmer goes better when the project is specific before code starts. MT4 and MT5 projects depend on the MQL version, broker behavior, symbol settings, order handling, lot sizing, stop-distance rules, and the difference between tester behavior and live use.
Moore Tech offers MetaTrader programming for MQL4 and MQL5 indicators, expert advisors, scripts, repairs, conversions, and broker-aware workflow tools.
What A MetaTrader Developer Needs First
Before asking for a quote, collect the details that define the platform behavior:
- whether the target is MT4 or MT5
- broker name, symbol names, suffixes, lot step, and account assumptions
- MQL source files, compiled files, screenshots, and error messages
- entry, exit, stop, target, filter, and trade-management rules
- examples of correct behavior and wrong behavior
- whether the request is a repair, conversion, indicator, expert advisor, or utility
- how the tool should behave in backtest, demo, and live use
If you do not have source code, send screenshots and a plain-English workflow. Moore Tech can still review whether the work is quoteable, but missing source can change the repair path.
MT4 Programmer Or MT5 Developer?
MT4 and MT5 are not interchangeable targets. An MT4 indicator or expert advisor usually cannot be treated as a simple copy-paste job into MT5. The target platform affects the language version, order model, tester behavior, and how a broker exposes symbols.
Use an MT4 programmer path when:
- the finished tool must run in MetaTrader 4
- the existing code is MQL4
- the broker, account, or workflow is tied to MT4
- the request is a repair or modernization of an older MT4 tool
Use an MT5 developer path when:
- the finished tool must run in MetaTrader 5
- the existing code is MQL5
- the project needs MT5-specific behavior
- the work is a conversion from MT4 to MT5 or from another platform into MT5
When the target is unclear, start with the MetaTrader MQL scope checklist before requesting a build.
Expert Advisor Scope
An expert advisor needs more than entry and exit ideas. A quoteable EA scope should explain:
- what conditions open a position
- what conditions block a trade
- stop, target, trailing, break-even, and exit behavior
- position sizing, lot limits, and account assumptions
- one-position, multiple-position, or grid behavior
- recovery behavior after restart, disconnect, rejected orders, or changed inputs
- symbols, sessions, time filters, and news or event filters if relevant
Moore Tech does not need performance promises to scope an expert advisor. It needs clear rules and platform assumptions so the software behavior can be reviewed.
Repair, Debugging, Or Rebuild
If the tool already exists, the first decision is whether it can be repaired. A small compile error, broken input, or broker-specific setting may fit a diagnostic path. A fragile expert advisor with unclear rules may need a rebuild instead.
Use the MQL code repair and EA debugging guide when you have:
- compile errors
- an expert advisor that behaves differently than expected
- indicator output that changed after a platform or broker update
- MT4 to MT5 conversion questions
- old MQL that is hard to maintain
Use paid support when the issue is bounded setup or troubleshooting instead of custom development. Use MetaTrader programming when the work requires new MQL code, a repair quote, conversion, or custom EA build.
What To Ask Before Hiring
Ask these questions before you pay for development:
- Is the target platform definitely MT4 or MT5?
- Do I have the MQL source files, or only compiled files?
- Can I describe the expected chart or trade behavior with examples?
- Are broker rules part of the problem?
- Is this a repair, conversion, fresh indicator, expert advisor, or workflow tool?
- What should happen when data, spread, account state, or order execution changes?
The clearer those answers are, the easier it is to quote the smallest useful next step.
