In India’s fast-moving financial markets, every tick counts — and so does regulatory compliance.
When you build trading systems, fintech platforms, or analytics tools, your data source must be both fast and exchange-authorised.
That’s where TrueData stands apart.
As an Authorised Data Vendor for NSE, BSE, and MCX, TrueData delivers real-time and charting-compatible market data APIs, along with corporate data feeds — all in strict accordance with exchange guidelines.
Whether you’re an algo trader, fintech developer, or institutional analyst, TrueData APIs give you authorised, accurate, and ultra-low-latency data designed for professional use.
The TrueData Market Data API provides direct, authorised access to real-time streaming and charting-ready market data from NSE, BSE, and MCX.
It delivers:
Live tick-by-tick data with ultra-low latency
Streaming feeds for OHLC, bid/ask, volume, and open interest
Market Depth (where available)
Options Chain with Greeks (Delta, Theta, Vega, Gamma, etc.)
Corporate Data APIs offering real-time insights on company disclosures
All data is delivered via secure, scalable APIs, purpose-built for traders, fintech firms, and institutions who require speed, accuracy, and compliance.
All market data remains the intellectual property of the exchanges (NSE, BSE, MCX).
Data is licensed, not owned. Users must follow exchange and SEBI-approved data policies at all times.
Data is licensed for individual or institutional internal use only.
You may analyse or visualise the data within your own systems or products.
Redistribution, resale, or public sharing of data is not allowed without prior written permission.
If you plan to:
Display data on a website or app for public or client access
Integrate live feeds into a commercial platform
You must first obtain written approval from the exchanges and TrueData.
Redistribution requires separate licensing and exchange documentation.
Only exchange-approved intervals can be offered:
Tick, 1-Minute, 2-Minute, 5-Minute, 15-Minute (Delayed), and End-of-Day (EOD).
Any changes to these intervals must be pre-approved by the exchange.
TrueData maintains detailed logs to monitor usage and prevent misuse.
Any unauthorised use, redistribution, or non-compliance may result in immediate suspension or termination of access.
