A Few Words About The Client

This project is a Zerodha-inspired stock trading platform that provides a modern, responsive experience for equity and derivative trading. Block Intelligence built the trading interface, order management, and integration layers to connect with market data and execution gateways while keeping latency and reliability as priorities.

The client wanted to offer a Zerodha-like UX-clean, fast, and mobile-friendly-with robust order types and real-time data. They needed seamless integration with existing broker/market infrastructure and compliance with local regulations.

Project Requirements

  • Real-time market data and order book display with minimal delay.
  • Order placement (market, limit, SL, SL-M) with validation and confirmation.
  • Portfolio and positions view with P&L and margin information.
  • Secure login, KYC linkage, and session management.
  • Compliance logging and reporting for audit and regulators.

Our Solution & Results

We developed a web and mobile-friendly trading front end with WebSocket-driven data and order submission. We integrated with the client's market data and execution APIs, implemented margin and risk checks, and added full audit trails and reporting hooks for compliance.

The platform went live for the client's user base. Order latency and uptime met targets, and user feedback on the interface was positive. The client has extended the product with new segments and order types using the same architecture.
