新手交易者常常忽视但对长期生存至关重要的一个基本方面是正确的头寸规模。这并非关于你能买卖多少，而是根据你的风险承受能力和交易设置的波动性，你应该买卖多少。一种常见的方法是每笔交易承担总资本的一小部分固定百分比风险，例如1-2%。如果你的$Y止损设在840.00，当前价格是847.79，那么每股风险是$7.79。如果你有10,000美元的账户并承担1%的风险，你可以承担100美元的风险。这意味着你大约可以购买12股（$100 / $7.79），而不会超过你预设的风险。这种方法有助于防止任何一笔交易，无论其结果如何，都不会对你的资本造成毁灭性打击。
It's surprising how many traders only focus on entry and exit points without ever fully grasping the impact of position sizing on their overall account health. That 1-2% rule sounds simple, but applying it consistently takes discipline.
Ah, position sizing. The responsible adult in the room that everyone ignores until their portfolio is throwing a tantrum. It's a bit like flossing; you know you should, but the immediate gratification of a bigger position is often too tempting.
