The Estimated amount is the amount that is required to make a successful transaction. This feature does not block or warn you if you have insufficient funds but helps you understand the amount you need before you place the order.
Currently, this feature is only available for Intraday and Delivery products when the complexity is selected as 'Simple'.
1. We do not check whether you have an open order or position while computing the Estimated amount.
2. The amount estimation feature does not provide an estimate for any span benefit getting derived after clubbing two or more orders/positions for Derivatives instruments. It only shows the amount for an individual symbol at a time.
