Fyers API v3 basics
Fyers provides API v3 with OAuth-based authentication. AlgoCrab uses this to place orders, fetch positions, and stream required market data for strategies.
Create an API app from Fyers MyAccount → API section before connecting.
OAuth connection flow
On AlgoCrab, open Connect Broker → Fyers and enter your App ID and Secret ID.
Complete the Fyers login redirect. After authorization, your session is linked and ready for algo execution.
Running strategies
Fyers is suitable for equity intraday and index options strategies. Use AlgoCrab backtester first to validate logic on historical Fyers-compatible symbols.
Webhook bridge from TradingView can trigger Fyers orders through AlgoCrab without custom server code.
Troubleshooting
If OAuth fails, verify app status is active on Fyers and redirect URI matches exactly.
Token expiry requires re-login — schedule daily authorization if you run unattended algos.
