Exchange Segment Codes

Exchange segment codes used across request and response payloads for order placement, market data, and symbol lookups.

Overview

Every API call that references an instrument — Place Order, Market Quotes, Search Scrip, and others — requires an exch field identifying the exchange segment. Use the exact code from the table below; values are case-sensitive.

Segment codes

Code	Exchange / Segment	Description
`NSE`	NSE Cash	National Stock Exchange, equity segment.
`BSE`	BSE Cash	Bombay Stock Exchange, equity segment.
`NFO`	NSE F&O	NSE Futures & Options — index and stock derivatives.
`BFO`	BSE F&O	BSE Futures & Options — index and stock derivatives. Note: `prd: "I"` (MIS) is not accepted on this segment — use `prd: "M"` (NRML) instead. See Product Type Codes.
`CDS`	NSE Currency	NSE currency derivatives segment.
`BCD`	BSE Currency	BSE currency derivatives segment.
`MCX`	MCX Commodity	Multi Commodity Exchange — commodity futures & options.

Not every segment is enabled for every account by default — commodity and currency segments in particular often require separate activation. Check the prarr array in your Funds & Limits or Client Details response to confirm which segments and product types are enabled for a given user ID.

Usage example

The exch field appears identically across order, data, and lookup APIs:

json

{
  "exch": "NFO",
  "tsym": "NIFTY28AUG26F",
  "buy_or_sell": "B",
  "qty": "50"
}

See Product Type Codes and Order Type Codes for the other coded fields commonly paired with exch in a request payload.
