Let’s say you place a buy order for a share with the following specifications:-
Current market price: Rs. 105
Limit Price set: Rs.100
Now if the market price suddenly falls from Rs.105 to Rs. 95, then the order will get executed at Rs 95 instead of Rs 100 because it's a better purchase price. This means you will be able to save Rs 5 in buying that share.
If you still feel that the order has not been executed at a better price, please contact our team for further assistance.
