MT5 EA Developer for Production MetaTrader 5 Bots
We architect MetaTrader 5 expert advisors for discretionary firms, prop traders, and fund desks—handling symbol specs, margin modes, and broker-specific execution quirks before you go live.
Why most MT5 EAs fail after the demo
Retail templates break when lot steps, swap schedules, and session gaps differ from backtests. Prop rules add another layer: daily loss caps, max lot limits, and news blackouts that generic EAs ignore.
- ×Backtests look profitable until slippage, requotes, and partial closes distort fill assumptions.
- ×Multi-symbol portfolios collide on margin and magic numbers without centralized risk controls.
- ×Prop-firm rule engines are bolted on late, causing disqualifying trades during volatility spikes.
- ×MQL5 codebases become unmaintainable when strategy logic, UI, and broker adapters live in one file.
MQL5 engineering built for live MT5 environments
We separate signal generation, order routing, and risk governance so each layer can be tested, versioned, and swapped per account profile.
- Symbol-aware position sizing with contract size, tick value, and step validation per instrument.
- Explicit handling of hedging vs netting accounts, partial fills, and order modification retries.
- Prop-compliant daily drawdown monitors with hard stops before rule breach—not after.
- Documented deployment runbooks for VPS, broker whitelist IPs, and rollback procedures.
Who hires our MT5 EA developers

Real-world delivery examples
Multi-pair prop EA with news lockout
A funded trader needed one EA managing EURUSD, GBPUSD, and USDJPY under a 5% daily loss cap with NFP blackouts.
Passed two verification cycles; average slippage within 0.3 pip of modeled assumptions over 90 trading days.
Vendor EA with tiered licensing
A strategy seller required hardware-bound licenses and remote disable without exposing source.
Shipped compiled EAs with online validation and a support dashboard cutting refund tickets by 40%.

Development process
- 01
Execution discovery
We map broker specs, account type, symbol list, and prop constraints before writing signal code.
- 02
Logic prototype
Signal rules coded with logging hooks; validated on tick data with explicit fill assumptions.
- 03
Risk hardening
Drawdown guards, lot validators, and failure modes for disconnects, margin calls, and partial fills.
- 04
Forward test & tune
Demo forward run with daily review; parameter locks once slippage budget is confirmed.
- 05
Live handoff
VPS setup, operator checklist, and 30-day defect window for execution-edge cases.
Frequently asked questions
Do you work with hedging and netting MT5 accounts?+
Yes. We branch order management for hedging (multiple positions per symbol) and netting (single net position) and test both in Strategy Tester with the correct account mode.
Can you migrate an MT4 EA to MT5?+
We port logic where MQL4 and MQL5 differ—order functions, indicator buffers, and event models—rather than relying on automated converters that miss execution details.
How do you validate prop-firm rules in code?+
We encode firm rule sheets as configurable thresholds—max daily loss, max open trades, lot caps—and unit-test breach scenarios before live deployment.
Will you sign an NDA for proprietary strategies?+
Standard for fund and vendor engagements. Source can remain in your repository; we work via private Git with least-privilege access.
What ongoing support do MT5 EAs need?+
Broker spec changes, symbol renames, and terminal updates. We offer monthly retainers for compile updates, log review, and parameter drift analysis.
