I am interested to open online trading a/c. i have demat account with ICICI. Is it possible to simply fill the form (sharekhan or ICICI or any other broker) which can be taken by my relative in Mumbai and submit it (forms will be physically delivered duly signed with photographs and proof of residence in India) since presently i am out of India. In case we open NRE a/c with ICICI, what will be the brokerage charges for tansaction and demat annual charges. Will there be diference wrt Indian a/c??
