Andrews’ Pitchfork is an instrument consisting of three parallel Trend Lines. This instrument was developed by Dr. Alan Andrews.
3 條平行直線的趨勢(shì)線,，由安德魯博士最先發(fā)現(xiàn),。

The first trend line starts in a selected extreme left point (it is an important peak or trough) and is drawn exactly between two extreme right points. This line is the "handle" of pitchfork. Then, the second and the third trend line issuing from two above-mentioned extreme right points (important peak and trough) is drawn parallel to the first one. These lines are "tines" of the pitchfork.

In our discussion of Andrews Pitchforks, the terms “price pivot,” and “pivot point” will be used quite often. A pivot point is the location of a price reversal. At a pivot point, price bars change direction. When price changes from an upward to a downward direction, a “top pivot” is formed. When price changes from a downward to an upward direction, a “bottom pivot” is formed. The following chart gives examples of pivots.

Multi-Pivot lines
Standard pivot lines (or trend lines) can be drawn by connecting two pivots. However, connecting several pivots creates a multi-pivot line. When drawing a multi-pivot line, it is not necessary to run through the exact high or low of each pivot. It is only necessary to be as close to each pivot as possible. Looking for trend lines that can be drawn through a large number of pivots is important. The more pivots through which the trend line passes, the more accurate the trend line will be in predicting future support and resistance.
一大段英文就一句話：短期的極值點(diǎn)叫做軸心點(diǎn)（附近價(jià)格運(yùn)動(dòng)受其附近軸心影響），軸心點(diǎn)的連線就是我們常說的趨勢(shì)線了,。

The Andrews Pitchfork
Alan Andrew’s Pitchfork consists of four main lines. The first line is the only line that is not provided by the Andrews Pitchfork indicator tool. This line must be constructed by connecting two pivots that are a recent high and low of a price swing.Once the line has been constructed, move your cursor so that it is touching the line and right click. When you right click the mouse, a list of indicators will be displayed. Move your cursor so that “Andrews Pitchfork” is highlighted and left click. The Andrews Pitchfork will now appear on the screen.
選擇兩個(gè)軸心點(diǎn)（一高價(jià)軸心,，一低價(jià)軸心），拉動(dòng)鼠標(biāo)到臨近第三個(gè)軸心,，安德魯魚叉就自動(dòng)由計(jì)算機(jī)生成了,。

The Median Line Within the Andrews Pitchfork
The next line within the Andrews Pitchfork is the most important. This Line is the median line. The median line runs through the center of the first line, which you drew on your chart, and it determines the angle of the Andrews Pitchfork. To properly position Andrews Pitchfork, locate a third pivot that occurs before the price swing. Usually this will be the pivot immediately before the price swing, but it does not have to be. Once you have located the pivot that you will be using, move the tail end of the median line so that it touches the pivot.

Three Median Line Trading Principals
After years of use with the pitchfork and median line, Andrews made several observations that are important for traders. These observations can be summed into three basic principals that can help a trader know what to expect when using the median line of the Andrews Pitchfork.
1. When a median line is drawn from the most recent swings, the price will return to the median line approximately 80% of the time.
2. When price returns to the median line, a pivot will usually occur.
3. When price returns to the median line, it will often make several small price swings on and around the top and bottom of the median line before continuing on.

魚叉使用三原則：
1：魚叉八成都能捕獲到魚（價(jià)格運(yùn)動(dòng)回歸中心線）
Dr. Andrews suggested that prices make it to the median line (or handle) about 80% of the time while the price trend is in place. This means that while the basic long term price trend remains intact, Dr. Andrews believed that the smaller trends in price would gravitate toward the median line while the larger price trend remained in tact. When that does not occur, it may be evidence that a reversal in the larger price trend may be in progress or provides evidence of a stronger bias at work in market. When price fails to make it to the medial line from either side, it is often an expression of the relative enthusiasm of buyers and sellers and may predict the next major direction of prices. If prices fail to reach the median line while above the median line, it is a bullish and failing to reach the median line from below is bearish.
回歸中心線證明長(zhǎng)期基本趨勢(shì)仍然存在，如果沒有回歸顯示反轉(zhuǎn)正在發(fā)生或者市場(chǎng)相對(duì)原有趨勢(shì)出現(xiàn)了劇烈的偏離,。在回歸的過程中受到中心線的支撐和壓制反映出買方和買方的交易信心,。
2：一旦捕獲（價(jià)格運(yùn)動(dòng)回歸中心線）即刻生成新軸心點(diǎn)。
3：一旦捕獲（價(jià)格運(yùn)動(dòng)回歸中心線）一定被中心線固定住一段（中心線附近波動(dòng)一段）


Locating highs and lows
The trick to trading these signals is being able to properly locate a true high or low in the market as opposed to a pause in the market trend. There are 3 different pattern formations you can use to help you determine a true reversal.
魚叉的使用目的：識(shí)別真正的高低轉(zhuǎn)折點(diǎn)和短時(shí)極值點(diǎn),，以便確定趨勢(shì)的反轉(zhuǎn),。
Method 1: Wait for a second pivot point on your lower or upper parallel line.
方法一：新軸心點(diǎn)的相對(duì)位置。
Method 2: Look for center points within the pitchfork.
方法二：圍繞魚叉中心點(diǎn)是否據(jù)有支撐或阻擋的能量,。
Method 3: Recognize reversals by analyzing candlestick patterns. There are 3 common reversal patterns found within candlestick formations.
方法三：參考軸心點(diǎn)K線組合的反轉(zhuǎn)作用

A Fourth Median Line Trading Principal
If price does not reach the median line, price will move in the opposite direction more than the previous swing size.
This principal can be used to set a price target after price fails to reach the Median line. After price fails to reach the median line, the first price target is either the high or low of the two pivots selected in constructing the first line of the Andrews Pitchfork. This holds true because once price fails to reach the median line, it will move in the opposite direction more than the previous swing size.

Upper and Lower Parallel Lines of the Andrews Pitchfork
The remaining lines, which make up the Andrews Pitchfork, are the upper and lower parallel lines of the median line. Upper and lower parallel lines are used in conjunction with signal lines.
Signal Lines
The chart below displays a pitchfork with points labeled A, B, and C. Point A is the pivot that occurred before the price swing. Points B and C are where the upper and lower parallel lines extend from the original line you drew. Connecting points A and B gives you an upper signal line and connecting points A and C gives you a lower signal line. These signal lines can give signals to either buy or sell when used with a few trading rules.

The Andrews Pitchfork with Signal Lines Trading Rules
Buy Rule 1: Buy when price breaks above a downward sloping upper parallel line. It’s an indication of market strength
Buy Rule 2: Buy on a downward sloping pitchfork and an upper signal line when price reverses without touching the median line and breaks the upper signal line.
Sell Rule 1: Sell when price breaks below an upward sloping lower parallel line. It’s an indication of market weakness
Sell Rule 2: Sell on an upward sloping pitchfork and a lower signal line when price reverses without touching the median line and breaks below the lower signal line.

Mini Andrews Pitchforks
Mini Andrews Pitchforks are drawn the same way as normal Andrews Pitchforks, except they are drawn with the use of much smaller pivots. Mini Andrews Pitchforks are applied to charts to search for a signal from a larger Andrews Pitchfork. The Mini Andrews Pitchfork will often give a signal before the larger Andrews Pitchfork. An aggressive trader may use the Mini Andrews Pitchfork signals alone, but often they are used with a larger Andrews Pitchfork to find signals before they are given.
The buy and sell rules for the median lines of Mini Andrews Pitchforks are the same as the buy and sell rules for the median lines of regular Andrews Pitchforks.

The Mini Andrews Pitchfork will not always be used to give early indication of buy or sell signals along a current trend. Sometimes the Mini Andrews Pitchfork will be used to determine which direction price will move while it makes a sideways formation within a larger Andrews Pitchfork.
The following chart contains a Mini Pitchfork within a Large Pitchfork. Here, the use of a Mini Andrews Pitchfork with signal lines can help determine whether price will rise to the upper parallel line, or fall back down to the lower parallel line of the large pitchfork. A downward Mini Andrews Pitchfork is drawn in red. Price is unable to drop to the mini’s median line and then rises above the lower mini signal line. This move indicates a mini buy signal, which can be used to enter the market.
