I have Demat, Trading with geojit can I open only Trading Account with Zerodah and link it to my Geojit Demat. I asked Geojit they told that they wont charge any fees . Here I understand FEES as,,, that apart from AMC (ANNual Maintenance Charges) there is no any other charges or fees  for the shares to get settled in DEMAT. Kindly Clarify my Doubts.
