Optional Enhancements

Multi-tenant API gateway rules, rate limiting / circuit breakers, market data caching layer, and regulatory reporting format converters for compliance auditing.

Core Advantages

  • Years of experience in finance and trading, familiar with broker/exchange protocols
  • Runnable source code and API documentation, enabling rapid integration and further development
  • Compliance-first: guidance on KYC, auditing, and data minimization
  • Cross-platform support: Android/iOS client interaction emulation and server-side adaptation

Suggested Integration Architecture

Based on a microservices architecture:
- Identity & Authorization service (OAuth2 / OIDC)
- Market data proxy (WebSocket cache + REST history)
- Trade gateway (idempotency, concurrency control, reliable callbacks)
- Compliance & audit module (immutable logs, encrypted storage)

API Integration Guide (Quick Start)

1) Initial Information

  1. Provide target functionalities (e.g., order placement, market data subscription, account reconciliation).
  2. If credentials or a test environment exist, provide them (our contract and authorization will govern usage).
  3. Confirm compliance boundaries (whether KYC is required, whether transaction wiring is allowed).

2) Recommended Technical Implementation (Sample)

// OAuth2 token retrieval (example) POST /oauth/token grant_type=authorization_code&code=&redirect_uri= // WebSocket market heartbeat example const ws = new WebSocket('wss://api.gateway/market'); ws.onopen = () => ws.send(JSON.stringify({op:'subscribe',symbol:'RELIANCE'})); ws.onmessage = (msg) => console.log(msg);

3) Delivery Timeline Estimate

Typical small-to-mid sized integration (login + trading + market data): 5–12 business days. More complex programs (custody, trading venue integration, regulatory reporting) will be assessed by scope.
