Like limiting buy quantity upto 2,50,000 shares per script. Is there anything such in Indian markets?
No such limit, i think you can purchase max upto 5 crores in single Client ID per scrip.
Edit:
Sorry about it, I couldnt find the reference link. As Nithin said, limit exists only on per order basis, I think.
But here are position wide limits for FnO sector (in below links). For Equities, I believe no limit is applied, on how much you can buy and hold.

There is an order limit of 9.99 lakh shares per order. You can place multiple orders, and no limit on how much quantity you can buy.
Why 5 crores? We don’t have such limitations on Wall Street. Why in India then? And, what if we intend to buy above 5 crores like 12 crores in a single script?
Edited above in the answer.
