For me, it depends on what your goal is. This comes down to scalp versus swing. If I’m buying a breakout and I’m doing it for a scalp, I don’t want the market to come back. I’m pretty quick to get out. If I think that a pullback is acceptable, a lot of times I’ll scale in during a pullback. But if I’m looking at a pullback and I’m saying, “Wait a minute, it should not be doing that,” then I get out. | For me, it depends on what your goal is. This comes down to scalp versus swing.

Now first of all, context is a little bit different. Here we get a wedge bull flag, we’re getting late in the day, 11:30 for trend resumption or trend reversal. And then also as 61 was forming, I tried, it was going up very quickly—I placed a limit order to buy a two tick pull back. And instead of pulling back, it went up like three or four ticks and I was thinking to myself, “Oh, that’s bad. That’s bad. I’m going to get trapped out.” So I just hit ‘Buy the Market’ and I keep my fingers crossed. | ||
当61 的 突破正在进行时 , 我们要如何拿它来 与28或38比较 ? 首先, 形势 有点不同。 在这里 (61) ,我们 有个wedge bull flag(WBLF) , 而且这时候 已经 是太平洋时间 晚上11:30 (北京时间凌晨2点半) , 一般在这时间我们都会看到 趋势恢复或趋势逆转。 然后,当61正在形成时,它上涨得非常快 , 我 尝试用 了一个限价单来购买两 个tick的 回 调 。 但 是 ,与其 回 调 ,它 反而 上升了三或四 个tick ,我正在想“哦,那糟糕 了 。我会 失去入场 的 时机 。” 于是 我 就 只 好以市价单立刻 入场,然后 希望市场会继续上升 。 | |||

I knew that I wanted to buy and I usually try to buy with a limit order. And I probably did buy on a limit order on 28 or 27 or 37. Because that’s what I typically do. But here [36/49/57], I thought that we had a wedge and a micro double bottom like we’d go to the bottom and that we had the potential to get up to the 60-minute moving average for the high of the day so I thought there was a potential for a breakout. | I knew that I wanted to buy and I usually try to buy with a limit order.

这 | 当你一直在想 这 样处于交 易 区的 市场 中 连续交易了2个小时 ,你很容易对于市场的波动变得冷漠 。但是大约 在太平洋时间11 点、11点半或12点左右 (北京时间凌晨2点至3点之间) ,我总是开始更加 留意 市场 任何 趋势恢复或趋势反转的迹象。因此,你想知道28和38 会 不会强烈看涨 : 首先,28 是处于tight bear channel(TBRCH),所以 这可能 只 是次要反转 ;而38 是交易区间日的第二个上涨,而且 它的涨幅 并不是很大,所以我对 与会不会强烈看涨 并不太确定。 | ||

Well, two things. You’ve got this big-bull reversal bar, you always hear me talk about those bars being limit order bars with sellers above. Those sellers are scalpers. If the context is good, here we’re in a bull trend, at the moving average, I think most of the time you make a profit buying above 58. But you need a wide stop. And the alternative is instead of buying above 58, you place a limit order to buy a 50% pull back. And then 61, now we have a second entry buy setup, with closing on its high at the moving average. To me, that’s even a higher probability buy than buying above 58. | Well, two things.

这里有 两 点 你 需要注意:57是 一个很大的反转 阴线 ,你常听我谈论这 些K线会吸引空头在这K线的 上 方挂 限价 单, 那些 空头都 是 刮头皮 交易 员 。如果 形势不错 , 就像 在这里我们 正 处在多头趋势中,而且在移动平均线上,我认为大多数 的 时 候 你 在58 上 方 的位置 做多 会盈利 , 但你需要一个宽松的止损。另一个选择是,不是在58以上买入,而是在50%回 调 处 挂限价单 。然后, 在61 我们有了一个第二次入场的机会, 这K线 在移动平均线上收盘 接近 高点。对我来说,这比在58以上买入 有 更高的概率。 | |||

刮头皮还是波段? Scalp or swing?[编辑 | 编辑源代码]

I’m pretty quick to get out. If I think that a pullback is acceptable, a lot of times I’ll scale in during a pullback. But if I’m looking at a pullback and I’m saying, “Wait a minute, it should not be doing that,” then I get out.
For a swing trade, depending on how big of a swing, and how far the target is, you have to allow pullbacks. You have to assume that there’ll be pullbacks. As long as your premise[1] is valid and as long as the market — in this case, a bull trend — as long as every pullback stays above the most recent breakout low.
对于我来说,这取决于您的目标是什么。这归结为刮头皮与波段的区别。如果我正在购买突破并且我是为刮头皮而做的,我不希望市场回调到我的入场点,所以我很快就会离场。如果我认为回调是可以接受的,很多时候我会在回调期间逐步加仓。但是,如果我正在看回调并且我说:“等一下,不应该这样做,”那么我就选择离场了。
对于波段交易,取决于波段程度和目标的远近,您必须允许回调,而且您必须假设会有回调。只要您的假设还未证实无效的,只要市场(以牛市为例)每次回调都保持在最近的突破低位之上。
反转信号 Reversal signal[编辑 | 编辑源代码]
Sometimes you'll get a reversal signal before the market falls below a low. So let's say you're long up here [B44/45], your stop is down here [below B38]. But let's say you decided to short below 57 or below 64, taking a chance for a Major Trend Reversal, that's okay. So, you can get out even though it's still Always In Long. But the Always In Long bulls strictly speaking, until they see a strong reversal down, they stay long as long as it's staying above the bottom of their last leg up.
有时候在市场跌破低点前,您会看到反转信号。假设您在这里(44/45)做多,您的止损位在这里(低于38)。但是,假设您认为 Major Trend Reversal (MTR)正在进行中,决定在57以下或64以下做空 ,那也可以。因此,在 Always In Long(AIL)的情况下,您也可以离场。如果依照 Always In Long 严格要求,在看到强烈的逆转K线之前,只要市场保持在上一个上升趋势的底部以上,多头就会一直持仓。

当你一直在想这样处于交易区的市场中连续交易了2个小时,你很容易对于市场的波动变得冷漠。但是大约在太平洋时间11点、11点半或12点左右(北京时间凌晨2点至3点之间),我总是开始更加留意市场任何趋势恢复或趋势反转的迹象。因此,你想知道28和38会不会强烈看涨:首先,28是处于tight bear channel(TBRCH),所以这可能只是次要反转;而38是交易区间日的第二个上涨,而且它的涨幅并不是很大,所以我对与会不会强烈看涨并不太确定。
在61,我们有 wedge higher low 和一个非常大的阳线,甚至是当天最大的阳线,我们还正突破 wedge bull flag 或 triangle(TRI)的区间。另外,我试图做多但无法以我平常的方式入场,所以市场的性质可能将会发生变化。
Question 3. You mentioned that you missed the buy on the close of 61. What told you that it was a breakout while still in a sideways trading range? 问题3. 你提到错过了61的尾盘买入机会。在当时仍处于交易区间,是什么让你认为这是一个突破?

Well, two things. You’ve got this big-bull reversal bar, you always hear me talk about those bars being limit order bars with sellers above. Those sellers are scalpers. If the context is good, here we’re in a bull trend, at the moving average, I think most of the time you make a profit buying above 58. But you need a wide stop. And the alternative is instead of buying above 58, you place a limit order to buy a 50% pull back. And then 61, now we have a second entry buy setup, with closing on its high at the moving average. To me, that’s even a higher probability buy than buying above 58.
这里有两点你需要注意:57是一个很大的反转阴线,你常听我谈论这些K线会吸引空头在这K线的上方挂限价单,那些空头都是刮头皮交易员。如果形势不错,就像在这里我们正处在多头趋势中,而且在移动平均线上,我认为大多数的时候你在58上方的位置做多会盈利,但你需要一个宽松的止损。另一个选择是,不是在58以上买入,而是在50%回调处挂限价单。然后,在61我们有了一个第二次入场的机会,这K线在移动平均线上收盘接近高点。对我来说,这比在58以上买入有更高的概率。
