Anyone tried changing the collateral quantity in NSE NOW ? Ex: I have pledged say 100 units of liquidbees, Some portion is used in margin,I want to sell say 50 liquidbees units which are not yet used for margin. I see that there is one option update collateral , Can we use it ? How to set the collateral quantity to 50 out of say 100 so that I can sell 50 liquidbees units
