Limit Order refers to a buy/sell order with a limit price. The investor specifies the price while placing the order.

For example: The quote of Stock is Rs.100 (Ask) and the client places a buy order for the same stock at Rs.80, then Rs. 80 is the limit price and the order is a limit order. 

You can place a Limit Order in any scrip via Dhan, either from investing (delivery) or for trading (intraday).
