How to book shares purchase sale invoice

We are private limited co dealing in share investments. How can we book purchase and sale entries of shares in our books. We are receiving invoice for share trading as gross rate * quantity + brokerage + exchange charges + sebi turnover fees + stt + stamp duty + gst. How can we book this entry ? Should i show brokerage separately? How should I book if there is different shares purchase and sales transactions in single invoice? There is no biferfication of charges according to shares i.e. on total amount all charges has been charged. we are not claiming input of GST on these invoices as we are not registered under GST law.
