大家好，想快速谈谈头寸规模，因为我发现新交易者经常忽视它。这不是最吸引人的话题，但老实说，它是风险管理中最关键的要素之一，可以说比你的入场或出场点本身更重要。
基本上，头寸规模就是你如何确定在任何一笔交易中究竟要冒多少资本风险。这与你能开多少手无关，而是根据你的止损和如果止损被触发你愿意损失的账户百分比，你应该开多少手。例如，如果你决定只愿意冒你10,000美元账户的1%的风险，这意味着你在任何一笔交易中的最大损失是100美元。如果你的止损，比如在$TRYUSD上，设置为捕获20点的波动（假设，鉴于其当前水平在0.02125左右），那么你计算出使这20点波动等于100美元的手数。它比仅仅猜测更能有效地保护你的资本，也是长期留在市场中的关键。
Completely agree! I've seen too many accounts blow up because traders focus on the 'big win' without first nailing down how much they're truly comfortable losing on any given trade. Do you find most new traders gravitate towards fixed lot sizes, or do you see them trying to calculate a percentage of their account from the start?
It's true, nobody ever got rich by being sensible with position sizing, but they also didn't go broke doing it either. Funny how those less thrilling aspects are always the ones that keep you in the game.
