What is a base of charging Stamp Duty @0. 01%?

As per my knowledge, Stamp Duty Rate is based on the address of the client not as per the brokers.

My Correspondence & Permanent address is Ghaziabad (U.P.) & as per ARTICLE 43 OF SCHEDULE I-B OF STAMP-DUTY ON INSTRUMENTS UNDER THE INDIAN STAMP ACT, 1899 AS
AMENDED UPTO DATE IN ITS APPLICATIOIN TO UTTAR PRADESH
