I do not trade in Futures and Options. But opened for cash online trading 'Race Pro' a/c. which was on 15500/- adv. payment towards brokerage. Brokerage was : 0.15 for delivery and 0.015. Yet, I closed the a/c, within 1 or 2 months for the reasons (1) worst software (2) poor customer service (3) poor contact facilities i.e. e-mails return even from given e-mail ids and (4) scrip wise individual transactions totals are not given in contract notes. My sincere advise is do not be lured by low brokerage.
