dear Avinash
Always remember to add your expenses in purchase price!
Brokerage +Security Transection Tax + Regulatory Charges % +Stamp Duty + Service Tax (These are all in Percent)
Double that amount as these are charged for purchase and sale separately.
Now you add the amount in purchase price to get the no profit no loss sale price.
Brokers do charge minimum brokerage, Ask your RM about the complete detail for above said Charges along with other charges like late payment charges Interest rate etc.
Happy trading!
