The "lite mode" in FYERS API v3 WebSocket is designed for developers who need quick access to price updates without extra data. It’s a lightweight, real-time streaming option focused exclusively on delivering the Last Traded Price (LTP) for subscribed symbols.
Lite mode minimizes bandwidth and data complexity by sending only the LTP, making it ideal for watchlists, tickers, or mobile apps. It skips deeper data like Open, High, Low, Close, and Volume (OHLCV) or order book depth, reducing parsing and processing requirements.

lite
. Example:{
"symbol": ["NSE:TCS-EQ", "NSE:INFY-EQ"],
"type": "lite"
}
Scenario | Outcome |
---|---|
You want to show only the latest price | Lite mode is the most efficient option |
You need volume or high/low data too | Use symbolUpdate mode instead |
You send an incorrect mode or format | FYERS will ignore or reject the subscription silently—double-check your syntax |
