How can we by GOI bonds from Secondary Market

@VenuMadhav @siva

Hello Zerodha Team:

Though the liquidity is less for the 20 year GOI bond, if i want to buy these bonds what are the options? How can we buy them from the secondary market through Zerodha?

Currently due to inter depository issue similar to that of SGBs(gold bonds) buying on secondary is not allowed. Also liquidity is null, ideal way of buying is via auction by RBI, can able to participate in auction through coin.
