Mr. Rao, I've been actively trading with Rkglobal for the past few days and yes, they do levy 'other charges' (0.006% of total turnover). Other brokerage firms too levy such charges. Take a closer look into the sheets and you will come to know. However, with RK's ultra low brokerage (Rs. 9 + Rs. 9.27 ST), total charges that a trader has to pay for buying and selling one lot of copper is just Rs.50/- (including the 'other charges' in question). That equates to just 0.05 pts of copper price. Hope this helps :thumb:
