@Hrishikeh Keep applying.
It's totally luck.
Before august 2023, I got allotment back in decenber 2021.No allotment in more than 70 IPO ( mainline + SME)
Till now, I have applied in 47 SME IPO, 0 allotment, yet applied in maitreya and transsteal to get first.
I personlly believe some registrar favor you, some not. (Try to get from your past allotment if any)
Since I opened demat account in 2021, I got 8 mainline IPO allotment from linkintime, 1 from kfin.
For bigshareonline, skylinerta, maashitla It's still 0. So i prefer registrar over premium.
