Thank you for writing in. Stoploss is a type of order you place to buy or sell a particular security to secure yourself against losses. Trader’s risk appetite defines the limit. The order is placed with a broker to buy or sell a security when it reaches a certain price. These orders are designed to limit an investor’s loss on a position. For instance, a trader may buy a stock and places a stoploss order 5% below the purchase price. If the security drops just below 5% level, stoploss order gets activated, and the stock will then be sold as a market order. I hope that helps. What exactly do you want to know about stamp duty?
