Stop loss is not based on perfect science, but on chance

More precisely, it is based on the probablity derived from historical data. Because it is a probablity, it would work sometimes but fail othertimes. As long as you undertsand and are willing to accept your fate when probability goes against you, it is ok to have a stop loss target in mind, assume you adopt a system where such probablity is high enough to allow you profit over time

• 但必需声明，止损的决定应该是罕见的，因为如果你买入一只股票的原因是长远的，那么卖出的原因就不应该是某些琐碎短期的事情 -monseigneur- ♂ (0 bytes) () 10/10/2025 postreply 21:19:17

• 是的，实际上止损应该发生在买入之前，一个不值得玩的游戏根本不需要开始 -monseigneur- ♂ (0 bytes) () 10/10/2025 postreply 21:53:35
