Kinds of 1Rev
https://ninetrans.blogspot.com/2011/10/kinds-of-1rev.html
One of the reasons 1Rev has been hard to explain is that its really a composite of various kinds of setups that happen to reverse at the high or low of the day during the first hour. Some days have more than one kind of 1Rev, leading to multiple labels on the chart. To make it easier to explain, Im splitting it into simpler components, hoping this would easier to explain and adopt.
The first kind of 1Rev is actually a fBO of the opening range. If the fBO produces a decent signal and the range is sufficiently large (say 4 points) then it should be tradeable for at least a scalp. This is best labeled as fBO instead of 1Rev.
The second kind of 1Rev is a reversal of the HLC of the prior day. Normally a such a reversal usually seeks the one of the prior day's extremes. This should probably be called Opening reversal (OR).
The third kind of 1Rev is a pullback from a gap to the ema and reversal. This can act like an A2 and is usually a high probability setup.
The last kind of 1Rev is a trend move from the open that violently reverses (b7,8). The last two are high probability high or low of the day and can lead to swing till end of day (as today did).
The first should simply be labeled fBO. The second can be labeled OR. The third and the fourth are traded similarly and should probably be labeled XOD (extreme of day).
I will move to the new nomenclature and avoid using 1Rev as a label. When more than one kind of 1Rev occurs, I may simply put 1Rev for brevity but will try to put the individual components where possible.
1Rev一直难以解释的原因之一是，它实际上是各种设置的综合体，这些设置碰巧在一天的第一小时内的高点或低点发生逆转。有些日子有不止一种1Rev，导致图表上出现多个标签。为了便于解释，我把它分成更简单的部分，希望这样更容易解释和采用。
第一种1Rev实际上是开盘范围的fBO。如果fBO产生了一个像样的信号，而且范围足够大（比如4个点），那么它至少应该可以进行头皮交易。这最好标为fBO而不是1Rev。
第二种1Rev是对前一天的HLC的反转。通常情况下，这样的反转通常会寻求前一天的极值之一。这可能应该被称为开盘反转（OR）。
第三种1Rev是指从缺口到ema的回撤和反转。这可以像A2一样，通常是一个高概率的设置。
最后一种1Rev是指从开盘开始的猛烈反转的趋势移动（b7,8）。最后两种是当天的高点或低点的高概率，并可能导致波动，直到一天结束（如今天）。
第一个应该被简单地标记为fBO。第二个可以标记为OR。第三个和第四个是类似的交易，可能应该被标记为XOD（一天中的极端）。
我将改用新的命名法，避免使用1Rev作为标签。当出现一种以上的1Rev时，为了简洁起见，我可能只写上1Rev，但在可能的情况下会尽量写上各个组成部分。
