你总要最大的杠杆。
如果你用这么大的杠杆乱来，那你迟早要跪的。如果你选了这么大的杠杆，那么你要考虑的就是“保证金”，你可以想象一幅画面，你脖子上戴着300克拉的钻石金项链，被一群内衣模特团团围住。
原因如下。
你交易外汇的时候，是要扣除保证金的，账户中剩下的钱是“可用保证金”。我喜欢可用保证金。有些人看黄片，但是我会闭着眼睛想我的可用保证金。
可用保证金有什么特别之处？
它是我交易成功的前提。我可以用这部分资金做更多的交易，这里是我喘息休息的地方。我希望休息的空间越大越好，进行的交易越多越好。我不想一笔交易就扣掉我一半的钱。
监管机构不想你有太多保证金，他们不信任你，但是我信任你。
另一方面：如果你刚开始交易外汇，想让你的小账户像滚雪球一样越滚越大，那么你需要保证金。现在很流行这样一句话：“天哪，你用了这么多保证金，不怕爆仓吗？”其实你很聪明，不会让爆仓发生的，你又不笨。这么跟你说的人一定是个笨蛋。
100:1？聪明点
如果你的交易账户里有1,000美金，你想用100倍的杠杆建仓，这意味着你可以用100美元来交易100,000美元的仓位，每波动一点，你会赚到（或亏损）10美元。每周做几笔20点的交易，这就很不错了。当然，你也可能亏损，不过放心，你会越来越聪明的。
在你开了一单之后，你的账户里还剩900美元的可用保证金，所以你的交易会对你产生一些影响，不过影响不大。你不用追加保证金，也不要感到有压力。
嘿，听着，我不是建议你在1000美金的账户里开1标准手（10万美元的仓位）的订单，我只是告诉你我喜欢决定权掌握在自己手中，而不是在政府那脏兮兮的限制保证金的爪子下。
Choosing The Right Leverage For Your Trades
You want the maximum leverage.
You want so much leverage that you are literally crapping leverage if you so much as bend your knees. You want so much leverage that next to the word “margin” in the dictionary, there is a picture of you wearing a three hundred karat diamond-crusted gold chain around your neck, surrounded by lingerie models.
Here’s why.
When you open an fx trade, you put down margin. And whatever is left in your account is “usable margin.” I love usable margin. Some guys watch porn. I just close my eyes and think about usable margin.
What’s So Special About Usable Margin?
It’s the room my trade needs to be successful. It’s margin I can use to take more trades. It’s breathing space for my trades. I want the most breathing space possible. I want to be able to open more trades. I don’t want to have to put a down payment of half my account just to open a trade.
The regulatory agencies don’t like you to have margin. They don’t trust you. I trust you.
And another thing: If you are starting out in forex, and you want to build a small account into something bigger, you are going to need margin. It is popular to say “Oh my god you are going to blow up your account if you use too much margin.” But the truth is that you are smart enough not to blow up your account. You are not an idiot. Anyone who tells you that is a bigger idiot than you will ever be.
100:1? Be Smart
If you have a $1,000 trading account and you want to build it up, you want 100:1 leverage. That means that you could put up $100 for a trade, and trade a $100,000 position, and you’ll be making (or losing) $10 a pip. Make a few 20-pip trades a week, and that’s some sweet profit. Of course, you can lose money, but listen, you’re going to be smart about the trades you open.
And after you open that trade, you have $900 in usable margin in your account, so your trade can move a little bit against you and it’s no big deal. You won’t margin call. You won’t have to be all stressed out about it.
And hey, listen, I didn’t just recommend that you trade a standard lot ($100k position) on a $1,000 account. I’m just saying that I like that the decision to do that is in your hands, not the government’s grubby little margin-restricting paws.
