大家好，我一直在深入研究头寸规模，它不仅仅是笼统的“不要冒太多风险”的口号。它实际上是根据你的账户规模和止损距离来计算你每笔交易的风险，然后调整你交易的单位数量。例如，如果你决定每笔交易只承担账户1%的风险，并且你正在考虑做多$CADUSD，止损设在0.717，入场价在0.71832左右，那么风险就是13.2点。然后你利用这个风险，结合你账户1%的风险，来确定你可以合理交易多少手，而不会过度杠杆化。我认为这是一个基本步骤，当人们只是追逐$ASML最近突破1800的走势时，往往会忽略它，但它确实决定了交易的持久性。
Ah, the ever-elusive quest to quantify risk. It's almost as if the market enjoys a good chuckle at our carefully calculated position sizes, only to then introduce an unforeseen gap or an overnight news bomb. Still, it's better than blindly throwing darts, I suppose.
Exactly, it's about defining that 1% or 2% risk per trade and reverse-engineering the position size from there. Too many people just buy an arbitrary number of shares.
