Stop-loss trading strategies most often involve placing an order that automatically sells a losing position to limit downside risk, according to Investopedia, but traders also use trailing stop orders to guarantee profits for a winning position.

Jason Van Bergen of Investopedia recommends a loss-limit system that limits downside risk by placing stop-loss orders at a level that would represent at most a 2-percent loss of the total equity in a trader's account.

Van Bergen also recommends using a similar strategy for an entire trading account, limiting monthly losses to 6 percent and closing all positions at that point.
Steve Sjuggerud of Stansberry Research recommends using a trailing stop strategy of selling profitable positions at a level that is 25-percent off of their high values.
