Since STT on equity delivery trades is applied to both buying and selling, calculating the average price is important. The formula is as follows:

Average Price= (Buy quantity × Buy price) + (Sell Quantity × Sell Price)

Buy Quantity + Sell Quantity

Or in simple terms:

Average Price = (Total cost of buying shares + Total proceeds from selling shares) / Total number of shares traded
