In the context of investing and crypto trading, a stop-loss order serves as a risk management strategy aimed at preventing excessive losses. When a trader sets a stop-loss order for an asset, they specify a price point; if the market price of the asset falls to this level, the order triggers an automatic sell order. This helps traders to exit their positions before further losses occur, particularly in volatile markets like cryptocurrency. Stop-loss orders can be set as 'stop-limit' orders, which specify both a stop price and a limit price, creating conditions under which the order can be filled. Alternatively, they can also be set as 'stop-market' orders, where the asset will be sold at the market price once the stop price is reached.
