@skychaser Not an expert with any tag.. but i can tell you what i would have done in your place.
Place 1-1-1 application each of every ipo in different demat accounts.
Funds Required (For easier calculation rounding the ipo lot to 15k):
15-15-15 = 45k for Doms.
15-15-15 = 45k for Inox
15-15-15 = 45k for India Shelter
Total funds used = 1.35 Lac..
Rest can be used for other upcoming ipos
