Why the contract showm 23MAR instead of 29MAR

I am checking the hindalo mar contarct and found something weired on zerdoha platform as comapred to another one

Here is the snap shot of HINDALCO MAR which load HINDALCO23MAR400CE

and while chekcing the same script on another broker HINDALCO 29 MAR 400CE

and on zerodha char candles are also diffreent from another broker

can you please check and let me know what actully happen

Hi @Onkar_Singh,

“23” here denotes the year 2023.

23 (Year)
MAR (Month)
400 (Strike Price)
CE (Call Option)

29 here looks like expiry date.

This post explains this in detail:

Thanks for clearing doubts
