Relation Between exch_seg from instrument json and exchange type in WebSocket API

sagargami777

Hi,
I am trying to find exchange type for in WebSocket API from exch_seg value in instrument json.

Can you provide Logic for this mapping? as Directly passing "exch_seg" does not return Market Data.

=> Unique Exchange from JSON
CDS
NCO
NFO
BSE
NCDEX
NSE
MCX
BFO

=>Expected Exchange Type in WebSocket API
NSE_CM = 1
NSE_FO = 2
BSE_CM = 3
BSE_FO = 4
MCX_FO = 5
NCX_FO = 7
CDE_FO = 13
