Lot Sizes Reference

Index	Lot Size	Exchange	Expiry
NIFTY	65	NFO	Tuesday
BANKNIFTY	30	NFO	Tuesday
FINNIFTY	25	NFO	Tuesday
MIDCPNIFTY	50	NFO	Monday

JSON Generator Endpoints

OpenAlgo provides JSON generators for easy webhook configuration:

TradingView JSON Generator

Blueprint: tv_json_bp, url_prefix="/tradingview"

Endpoint: /tradingview (GET renders the page, POST returns the generated JSON)

Features:

• Select symbol, exchange, product

• Two modes selected with the mode field in the POST body:

  • strategy (default): emits strategy: "TradingView Strategy" with action: "{{strategy.order.action}}", quantity: "{{strategy.order.contracts}}" and position_size: "{{strategy.position_size}}", for use with /api/v1/placesmartorder

  • line: requires action and quantity in the request and emits strategy: "TradingView Line Alert" with fixed values, for use with /api/v1/placeorder

• The generated JSON embeds the user's real API key, resolved through get_api_key_for_tradingview()

• The symbol is resolved through enhanced_search_symbols() and the first match is used

• Copy to clipboard

GoCharting JSON Generator

Blueprint: gc_json_bp, url_prefix="/gocharting"

Endpoint: /gocharting (GET renders the page, POST returns the generated JSON)

Features:

• Select symbol, exchange, product, action and quantity (all five are required)

• Emits strategy: "GoCharting" with pricetype: "MARKET", for use with /api/v1/placeorder

• Copy to clipboard
