From what I understand , Turnover ‘a’ is what is used by exchanges for calculating the charges ; and ‘b’ is for tax (audit) calculations. Is this correct ?
Also , at the eod NSE will send an alert for the day’s traded value , is this same as the turnover we see in the brokerage calculator ?
What are the implications here ,since the "Turnover/Traded Value " is far larger than the PnL ?
