MT5 API recommended for new development projects.

REST API and Web Integration

REST API enables web-based applications to integrate with trading platforms. Supports standard HTTP methods for account management and trading operations.

REST API Endpoints

Web API provides RESTful endpoints for common trading operations. JSON format ensures easy integration with modern web frameworks.

Endpoint	Method	Function
/account	GET	Account details
/orders	POST	Place order
/positions	GET	Open positions
/history	GET	Trade history

Core API endpoints:

• Account information and balance
• Market data and instrument details
• Order placement and management
• Trade history and statements

Authentication methods:

• OAuth 2.0 implementation
• API key authentication
• JWT token validation

Rate limiting specifications:

• 100 requests per minute for market data
• 50 requests per minute for trading operations
• 10 requests per minute for account information

WebSocket Real-Time Data

WebSocket connections provide real-time market data streams and order updates. Low-latency data transmission suitable for trading applications.

Data Stream	Update Frequency	Latency
Price Quotes	Tick-by-tick	<50ms
Order Updates	Immediate	<100ms
Account Changes	Real-time	<200ms

WebSocket features:

• Real-time price updates
• Order execution notifications
• Account balance changes
• Market depth information

WebSocket ideal for applications requiring real-time market monitoring.

API Authentication and Security

Secure authentication protects trading accounts and prevents unauthorized access. Multiple security layers ensure API usage remains safe.

Authentication Methods

Choose appropriate authentication methods based on application requirements and security needs.

Auth Method	Security Level	Use Case
API Key	Medium	Server applications
OAuth 2.0	High	User applications
JWT Tokens	High	Mobile apps

Security best practices:

• Use HTTPS for all API communications
• Validate all input parameters
• Log API access for monitoring
• Set appropriate timeout values

Store authentication credentials securely. Never expose API keys in client-side code.

Rate Limiting and Quotas

API rate limits prevent abuse and ensure fair usage. Different endpoints have varying rate limits based on resource requirements.

Request Type	Limit	Window
Market Data	1000/min	1 minute
Trading	100/min	1 minute
Account Info	60/min	1 minute

Quota management strategies:

• Implement exponential backoff
• Cache frequently accessed data
• Use WebSocket for real-time data

Design applications to handle rate limit responses gracefully.

Trading Operations via API

Execute trading operations programmatically through API endpoints. Place orders, manage positions, and monitor trade execution.

Order Management Functions

API supports all standard order types available on trading platforms.

Order Type	Execution	Use Case
Market	Immediate	Quick entry/exit
Limit	At price	Better fills
Stop	Breakout	Trend following
Stop Loss	Protection	Risk control

Order placement parameters:

• Trading symbol (e.g., EURUSD)
• Order type and direction
• Volume in lots
• Price levels (if applicable)

Order modification capabilities:

• Change price levels
• Adjust volume amounts
• Cancel pending orders

Validate all order parameters before submission.

Position Monitoring

Track open positions and monitor profit/loss in real-time. API provides detailed position information.

Position Data	Update Frequency	Calculation
Unrealized P&L	Real-time	(Current – Entry) × Volume
Swap	Daily	Interest differential
Commission	At open	Broker fee

Position management functions:

• Retrieve all open positions
• Filter positions by symbol
• Calculate total exposure
• Close positions partially or fully

Monitor position correlation to avoid excessive risk concentration.
