Lakshmishree charges ₹15 plus GST per ISIN for each pledge or un-pledge request.
This means: If you pledge shares of two different stocks, you will be charged ₹15 per ISIN, making it ₹30 + GST in total.
If you later un-pledge both stocks, the Same Charge Applies Again.
Pledging your stocks lets you use them as collateral for margin trading. When you un-pledge, those stocks are released back into your holdings.
