外汇交易轻仓是一种美德（转自ForexFactory，作者

亲爱的，我给你三个外汇交易必须轻仓操作的理由：扫损，扫损，扫损。

1，扫损。你永远不知道主力会不会扫损。如果发生了，那么你正好可以借此机会加仓，来降低你的平均成本。如果你本身是轻仓，那么你就可以抓住这样的机会。

2，扫损。你永远也不会知道，主力的扫损行为会有多么大的幅度。扫损行为甚至会中途暂停一下，然后再继续。而你正好可以借此机会加仓，来降低你的平均成本。前提条件很清楚，轻仓，你就可以抓住这样的机会。

3，扫损。你永远也不会知道，主力会进行几轮扫损，才会满意地让价格回到应该的方向上。所以，轻仓，你才能抓住扫损过程中为你提供的各类机会。

以上三条是你必须轻仓的理由。轻仓，可以让你扛得久，轻仓，可以让你吃得香。扫损行为其实是对即将到来的正确方向的一种确认，但扫损行为也会让你的账户有损失。交易，从来不会只赢不输。你也不要指望在主力扫损之后再入场 — 天知道主力什么时候才算完成了扫损。我们甚至不知道主力是否会采取扫损行为，更不会知道他们打算进行几轮扫损。解决方案只有一个：轻仓。

好吧，那么我们如何知道，如果价格在向着反方向走，这是主力扫损呢，还是走势反转了呢？很不幸亲爱的，咱们不可能知道。只有在经历了足够的价格行为之后，真想才能慢慢地被揭示出来。而在这过程中（在知道是扫损还是反转之前），你可能要蒙受很大的损失。而仓位越轻，你才能活的更久，才能有希望看到最后的结果。。。活的越久，你才越能有机会来判断和决定是否要进行下一步操作。

Trade Light Relative to Account Size

Sonicers,

I will give you three very good reasons to do this,…..stop hunts…..stop hunts……stop hunts:

1. Stop Hunts: You can never know if a stop hunt will happen. If it does, it might present an opportunity for a good addition to your trade and therefore a better average price for your trade. If you trade light relative to your account size then you can avail yourself of any such opportunity.

2. Stop Hunts: You can never know how great a stop hunt will be. It might pause and then go more. This can present an opportunity for an even better addition to your trade and therefore an even better average price for your trade. Trade light so you can avail yourself of any such opportunity.

3. Stop Hunts: You can never know how many stop hunts there will be before the Robber Banks finally get on with the trade! And sometimes the stop hunts get bigger. So, trade light so you can avail yourself of any good opportunity during any stop hunt.

These three reasons make it an imperative to trade light relative to your account size. Doing so will enable your trade to have "staying power" and "opportunity power" in the face of stop hunts, which are confirmations of the trade direction, but which will create draw downs on your account. There is no such thing as being able to trade without ever incurring draw downs. And there is no such thing as waiting to enter a trade only after the MMs have run the stops because we cannot know if they will even do that, or if they do, then how many times they might do it! The answer is to trade light – at entry and with additions – relative to your account size.

Okay, so how do we know if a move against our trade is a stop hunt or a reversal? We can't know! At least not right away. It will require enough PA to reveal what is going on. And over that time, the price can move considerably against your trade. And the lighter you trade relative to your account size the more time you buy yourself to see what might actually be going on,….the more time you buy yourself to decide if to fold, hold or add.
