You can find the definition here: https://tradesmartonline.in/help/trading/what-does-eq-and-be-series-stand-for-in-nse/

BEN = BE series
EQN = EQ series

in Some Scrip there is “BEN” at the end of identifier whereas more scrip has “EQN”. Whats the logic behind it ?? & New IPO scrip data is not showing ??

Hi, could you please share some example where it is not matching?
