我“平均成本法”的惨痛教训——更像是“加倍犯蠢”

由原文自动翻译 · 阅读原文 (English)

我想分享一个让我至今仍心有余悸的经历。早期交易$EURUSD时,我看到一个下跌,以为是“底部”。于是买入了一小笔头寸。结果它继续下跌。很自然地,我“聪明”的策略是平均成本法,相信反弹即将到来。然后又一次。又一次。每次都说服自己这肯定是底部了。账户亏损曲线就像滑雪道,我坐上了直达底部的特快电梯。最终亏损远超我最初止损所能承受的范围,仅仅因为我拒绝承认自己错了,并想证明自己对市场方向的判断是“正确”的。我的止损基本上被移到了“无限”或“直到它反转”——它最终确实反转了,但在此之前我的资金已经大幅缩水。最终的教训是?止损是有原因的,如果你无法承受最初的损失,就不要平均成本法;当你真正正确时,才应该平均向上加仓。

Ah, the classic 'buying the dip' strategy that quickly morphs into 'buying the dip's dip's dip' until you're at the Mariana Trench. I've got a frequent buyer's card for that particular rodeo myself.

That's a tough lesson, and one I've heard echoes of from many new traders. It makes me wonder, how do you personally differentiate now between a true dip to add to and just a falling knife?
