Broker limit for pledging

For the “Cash Component” section of the above sheet, I see “Broker limit reached” column only for the “ETF”, but not for MF, SGB and G-Sec.

How can I find out if broker limit for a particular G-Sec bond is reached or not?
I’m planning is to buy G-Sec bond via Zerodha Coin and pledge for margin.

Another question. When I try to buy “6.69% GS 2024” G-Sec via Zerodha Coin, it shows amount of “Rs 10,632” for 100 units. Does it mean the bond is available at a premium? i.e. face value = 100, but purchase price / unit = 106.32?
