Here are the best mobile apps for stock trading in India that provide live / real‑time market data, with a short summary of what each app is best at and why:

Top picks

• Zerodha Kite — excellent for active traders and algo users: fast mobile charts, WebSocket streaming and (beta) 20‑depth/Level‑3 market data for deeper order‑book visibility. Good reliability and low flat brokerage for intraday/F&O. (kite.trade)

• Upstox Pro — low‑cost, low‑latency mobile app with a WebSocket market‑data feed (real‑time LTP, depth, OHLCV) and advanced charting / scanners; popular with traders who want speed + APIs. (upstox.com)

• Groww — very user‑friendly mobile app that now offers real‑time charts, intraday screener and live LTP/P&L updates; best for beginners and investors who also want mutual funds/ETFs in the same app. (groww.in)

• FYERS — built for active/technical traders: low‑latency data WebSocket, advanced screeners and terminal tools with deep market‑depth (up to 50 levels in some terminals). Good for order‑flow / depth analysis. (support.fyers.in)

• 5Paisa — mobile app with TradingView/advanced charts, live option chain and real‑time market screens; cost‑effective for derivatives traders and those wanting integrated tools. (5paisa.com)

• Angel One — full‑service + discount hybrid with real‑time market watch, alerts, option tools and research; good if you want advisory/research alongside streaming quotes. (angelone.in)

• ICICI Direct (Trade Racer) — bank‑integrated 3‑in‑1 offering with live streaming quotes, scanners and research; strong if you prefer banking+broad offline support. (icicidirect.com)

What “real‑time” means here (short)

• Most Indian brokers stream live LTP (last traded price), bid/ask and multi‑level market depth to clients during market hours; exchanges also offer premium “tick‑by‑tick” feeds for ultra‑low latency institutional use — some brokers convert/offer deeper depth to retail (e.g., Kite’s 20‑depth explanation). (kite.trade)

Quick selection guide

• If you want the fastest updates, order‑book depth and APIs for algos: Zerodha Kite, Upstox, FYERS. (kite.trade)
• If you’re a beginner or want investing + simple trading: Groww, Angel One, 5Paisa. (groww.in)
• If you want bank/3‑in‑1 integration and research: ICICI Direct. (icicidirect.com)

Practical tips

• Check whether the broker/app shows streaming LTP only vs full order‑book (5 levels, 20 levels, or more) if you need depth for scalping. (zerodha.com)
• Confirm current brokerage, margin and data limits on the broker’s pricing page before opening an account (pricing can change). (zerodha.com)
• Try a demo/watchlist and small trades first to test app responsiveness and order execution during market open.

If you want, I can: (a) compare any two apps side‑by‑side (fees, depth, API, execution), or (b) list links to the official app pages and pricing/feature pages for the apps you care about.
