Trading symbols of Options

sachinstlko09

Hi,
Having a query related to option symbols. Some time I got the symbols like "BANKNIFTY2392038000CE", "BANKNIFTY2392038500PE" and some time did not get it.
Some time format be like this: BANKNIFTY23OCT38000PE, BANKNIFTY23OCT40000CE.

I have to form trading symbol dynamically on the basis of nifty bank LTP. So, we have to follow one proper rule.
Please suggest!

Hii @sachinstlko09 ,
as per my knowledge

#For Monthly Expiry

monthly expiry format ==> INDEX_NAME + YEAR + MONTH_NAME + STRIKE + INSTRUMENT_TYPE
ex., BANKNIFTY+23+OCT+40000+CE

#For Weekly Expiry JAN-SEP

all weekly expiry format ==> INDEX_NAME + YYMDD + STRIKE + INSTRUMENT_TYPE
ex., BANKNIFTY+23+9+20+40000+CE

#For Weekly Expiry OCT-DEC

again for M ==> {0:0,1:1,2:2,3:3,4:4,5:5,6:6,7:7,8:8,9:9,10:'O',11:'N',12:'D'}
ex., BANKNIFTY+23+N+01+44500+CE
