Zerodha API Trading Guide

Zerodha for automated trading

India's largest discount broker. Kite Connect is the most mature retail trading API in India and is widely supported by automated platforms. On the api trading guide side specifically, Zerodha's Kite Connect exposes the endpoints retail Indian traders actually need: order placement, positions, margins, and historical candles. Zerodha has 1.5 crore+ active clients, which means the API has been stress-tested across a wide variety of strategies. API cost: ₹2,000/mo.

Kite Connect supports REST endpoints for orders, positions, margins, and historical candles, plus a WebSocket feed for live ticks. Indian retail traders typically use the API for one of three things: automated entries based on technical signals, options-leg execution for spreads and condors, and end-of-day reconciliation for tax reporting. The API does not allow withdrawals — only trade actions and read access — which keeps the security profile narrow.

Pros of using Zerodha for automation: Largest user base, Mature Kite Connect API, Excellent documentation, Reliable order routing. Tradeoffs: ₹2,000/mo API fee, Strict order rate limits during high volatility. Sleeping Trade supports Zerodha alongside four other Indian brokers — your funds stay in your Zerodha account, and we connect via trade-only API keys that cannot withdraw money. You can revoke our access from your broker dashboard at any time.

Indian retail traders moving from manual to automated execution typically see the biggest gains not from a smarter strategy, but from better execution discipline — the same trade plan, executed mechanically every session, with stop losses honored without hesitation. That is what API-based automation delivers, and the broker you choose is just the rails the strategy runs on. Three things matter when picking a broker for algo trading: API stability under load, margin treatment for hedged positions, and brokerage costs at scale. All five major Indian brokers — Zerodha, Upstox, Angel One, HDFC Securities, and ICICI Direct — clear the bar; the rest is operational fit. Sleeping Trade is broker-agnostic, so you can switch later without re-learning the platform.
