Suppose you bought some shares of XYZ International at say 100Rs each. The next day when you would check your portfolio on Angel you would find that the price at which has been bought is 100+ or say around 102. The increased price just reflects the Brokerage and Charges which you have paid (Described in the contract note). It doesn't mean that you have been charged extra, it means that this is the avg price which you have paid for buying the shares.
