Standard Deliverables & Samples

Deliverables

  • Protocol analysis report (MT4 Manager/Server API / MQL4 / FIX bridging)
  • Operational connectors and runnable code (example: market data subscription, order bridge, accounting summary)
  • OpenAPI / Swagger documentation and SDK samples (Python / Node.js)
  • Automated tests and demonstration environment configuration guidance
  • Compliance and data retention strategy recommendations

Sample: Market Data Subscription (Pseudo-code / WebSocket)

// WebSocket Subscription Example (pseudo-code)
connect('wss://broker.example/mt4/quotes?token=')
send({action:'subscribe', symbol:'EURUSD', timeframe:'tick'})
on('message', (msg)=>{
  // msg => {symbol:'EURUSD', bid:1.09123, ask:1.09126, ts:1690000000}
  storeTick(msg)
})

Sample: Bridge for Orders (Pseudo-code / REST -> FIX/Manager)

POST /api/v1/mt4/order
Content-Type: application/json
Authorization: Bearer <SERVICE_TOKEN>

{
  'account_id':'ACC12345',
  'symbol':'EURUSD',
  'side':'BUY',
  'type':'MARKET',
  'volume':0.1
}

Response: {status:'accepted', ext_order_id:'BRIDGE-7890', exec_ts:'2025-11-01T10:00:00Z'}

API Integration Key Steps (MT4 ecosystem)

  1. Requirements confirmation: define data to synchronize (quotes, positions, transactions), trading mode (demo/real).
  2. Environment preparation: obtain MT4 Manager/Server API credentials or set up bridge (FIX/REST converter).
  3. Protocol analysis: map MT4/MQL4 data objects, order lifecycle, and acknowledgments to standardized APIs.
  4. Implementation & testing: develop quote subscription, order bridge, account sync, and reconciliation scripts; validate in sandbox or replay environment.
  5. Delivery & operations: supply source code, docs, test cases, and deploy monitoring, alerts, and audit logs.

Common Integration Considerations

  • Low latency requirements: streamline order execution paths with localized bridging services and fast networks.
  • Data consistency: ensure match confirmations, trades, and reconciliations align; implement idempotency and retries.
  • Compliance & logging: record data provenance, user authorizations, and data access per local regulations.
  • Backtest data quality: tick-level data must include timestamps, price deltas, and volume for accurate testing.
