Stop loss order
This is an order placed to sell below the current price (to close a long position), or to buy above the current price (to close a short position). Stop loss orders are an important risk management tool. By setting stop loss orders against open positions you can limit your potential downside should the market move against you. Remember that stop orders do not guarantee your execution price – a stop order is triggered once the stop level is reached and will be executed at the next available price.
