The Exchange and Exchange Segment should be represented as distinct entities as they are

Namaskara,

Lets take an example: The response body of GetOrderDetails

{
“status”: “success”,
“data”: {
“exchange”: “NSE”,
“product”: “D”,
“price”: 571.0,
“quantity”: 1,
“status”: “complete”,
“tag”: null,
“instrument_token”: “NSE_EQ|INE062A01020”,
“placed_by”: “******”,
“trading_symbol”: “SBIN-EQ”,
“tradingsymbol”: “SBIN-EQ”,
“order_type”: “LIMIT”,
“validity”: “DAY”,
“trigger_price”: 0.0,
“disclosed_quantity”: 0,
“transaction_type”: “BUY”,
“average_price”: 570.95,
“filled_quantity”: 1,
“pending_quantity”: 0,
“status_message”: null,
“status_message_raw”: null,
“exchange_order_id”: “1300000025660919”,
“parent_order_id”: null,
“order_id”: “231019025562880”,
“variety”: “SIMPLE”,
“order_timestamp”: “2023-10-19 13:25:13”,
“exchange_timestamp”: “2023-10-19 13:25:13”,
“is_amo”: false,
“order_request_id”: “1”,
“order_ref_id”: “GTT-C23191000044253”
}
}

Here Json Key Exchange has value “NSE”, however the list of Exchanges as provided in the appendix is as follows:

Description:

data.exchange : Exchange to which the order is associated. Valid exchanges can be found in the Exchange Appendix

Kindly note the word used is Exchange instead of Exchange Segment.

Valid (major) exchanges in Bharatha are:

1. NSE
2. BSE
3. MCX

However the list as per /appendix/exchange is as follows:

Value Description
NSE Represents equities traded on the National Stock Exchange.
NFO Futures and options segment of the National Stock Exchange.
CDS Currency derivatives segment for forex futures and options.
BSE Equities listed on the Bombay Stock Exchange.
BFO Futures and options segment of the Bombay Stock Exchange.
BCD Currency derivatives trading on the Bombay Stock Exchange.
MCX Commodity futures trading on the Multi Commodity Exchange.
NSCOM Commodity derivatives trading on National Stock Exchange.

Here the entities are mixed leading to confusion…

Let me put this way, the relation between Exchange and Exchange Segments.

Exchange CONTAINS Exchange Segments.

So they are distinct entities. That leads to following combination:

Exchange | Exchange_Segment

  1. NSE | NSE_EQ (NSE cash segment)
  2. NSE | NSE_FO (NSE Derivative segment)
  3. NSE | NSE_NSCOM (NSE Commodity segment)
  4. NSE | NSE_CDS (NSE Currency derivative segment)
  5. BSE | BSE_EQ
  6. BSE | BSE_FO
  7. BSE | BSE_BCD
  8. MCX | MCX_FO

Here we have segregated the entities to their respective sets.

This results in a clearer data representation, for ex:
“exchange”: “NSE”,
“exchange_segment”: “NSE_FO”,

I hope it gets implemented.
