In the instruments.csv file there are 2 types of symbols for BANKNIFTY. Can someone please explain these to me? I understand that 30900 is strike and "CE" is the type of option, but why are the dates given in 2 different formats?
BANKNIFTY20FEB30900CE is a monthly expiry instrument and BANKNIFTY2020630900CE is a weekly expiry instrument. You can refer to this thread to know more about the weekly tradingsymbol format.

Many thanks to both of you for clarifying this.
Specially the part about using O/N/D for months of Oct/Nov/Dec in weekly symbol.
Thank you so much!
