Small invester dont need to go with icici bank securiteis cause of it has too much brockrage and tax so small invester and treder will not get proper profit from them.
So my suggetion for smal trader have to choose discount brocker. For low brockrage and tax and also u can get more leavrage from them like 20x means 1000 for BO and CO type order ( compulsory 1.5% stoploss) it will be 20x1000= 20000 for MIS ( INTRADAY ) .
And limit order will be have 11x1000= 11000 ( intraday)
So this is better banifit u can from dicount broker insted of full broker.
Pls use brockrage calculator need understand more about what brockrage and tax will be diduct when put order.
