According to me, 1. charge are 95% cheaper and at RS 100 per oder. 2. techonology is more robust in this trading platform. 3. there is advance trading tool as compare to any other stock broker or demat account 4. MOST IMPORTANT IS free account opening. sharekhan is a traditional brokerage whose charge is extremly expensive.
for a trader and investor. in long run, charge would add up significantly.
