What is compulsory to use?

To me stop loss gets the most priority indeed. It ensures a trade to be secured. But I saw many traders are averse to using stop loss and for which they need to bear a huge sum of loss. Stop loss is a must for protecting a trade from being loss. A stop-loss order is an order placed with a broker to sell a security when it reaches a certain price. Stop loss orders are designed to limit an investor's loss on a position in a security. Trade12 offers such a trading platform which is free from dealing desk, reqoutes and slippage.
