成交量指標可以用來突出證券的不尋常交易活動。它能夠在一個單獨的窗口中顯示出日、週或月交易量細節圖。
示例
可口可樂公司股價的調整期對應的日成交量圖以及5日EMA。
上圖中的[1] 到 [4]處可以看到成交量增長迅速。前三處成交量的迅速增長是在收盤價接近最高價時，表明價格集聚（買方壓力）。[4] 處收盤價接近於價格的低點，預示著價格分散（賣方壓力）。[5] 處的低成交量說明趨勢的不確定性，但是接下來成交量的增長以及收盤價的升高，說明價格集聚。
設置
1. 打開技術指標設置窗口
2. 在左側選擇“volume”
3. 在下側的 Optional Indicator Smoothing, 設置移動平均線
(上述例子中設置的是成交量的5日EMA。)
4. [>] 保存參數設置
5. [x] 關閉技術指標設置窗口
成交量指標的顔色
在技術指標菜單中選擇 Volume With Close color ，這樣你就可以根據成交量柱狀圖的顔色來判斷收盤價上升或者升高。
成交量柱狀圖的默認顔色是綠色（收盤價上升）、紅色（收盤價下降）。你可以在圖表菜單中更改默認設置：Format Charts >> Colors >> Indicator Up (+) and Indicator Down (-)
成交量的標準偏差
成交量指標柱狀圖偏於繁雜，因此，我更傾向於使用成交量的標準偏差來突出顯示那些不同尋常的成交量（成交量高於或低於平時成交量的1~2倍標準偏差）。較高的成交量通常預示著當前趨勢的反轉，而較低的成交量則說明當前趨勢缺乏動力。成交量指標結合日蠟燭圖、支撐阻力位使用，會產生良好的效果。
默認設置是1倍標準方差以及30日MA.高成交量的默認顔色為紅色，低成交量為綠色。但是你也可以通過圖表菜單中的Format Charts >> Colors >> Indicator Up (+)and Indicator Down (-) 更改顔色設置。
Volume
Volume is used to highlight unusual trading activity in a security. It can be displayed as a separate indicator in Daily, Weekly or Monthly format.
Volume signals are covered in detail under Volume Patterns.
EXAMPLE
Coca Cola Corporation shows a close-up of a ranging market with daily volume and a 5-day exponential moving average.
Significant increases in volume can be seen on days [1] to [4]. The first three occur on days when price closes near the daily high, indicating accumulation (buying pressure). On day [4] price closes near the daily low, warning of distribution (selling pressure). Low volume on day [5] indicates uncertainty, but is followed by rising volume and strong closes, signaling accumulation.
Setup
See Indicator Panel for directions on how to set up an indicator. To alter the default settings - Edit Indicator Settings.
To create a Volume Moving Average:
1. Open the Indicator Panel
2. Select Volume in the left column
3. Under Optional Indicator Smoothing, set a moving average
(the above example has been set to a 5-Day exponential moving average of Volume)
4. Save [>] the indicator settings and
5. Close [x] the Indicator Panel.
Volume Colors
Selecting Volume With Close Colors in the Indicator menu, allows you to color volume bars according to whether price closes up or down on a given day.
Standard colors are green (Up days) and red (Down days) but can be varied by selecting Format Charts >> Colors >> Indicator Up (+) and Indicator Down (-) on the chart menu.
Volume Twiggs Standard Deviation
I prefer to have less clutter on the chart and only highlight days with abnormal volume. Select Volume Twiggs Standard Deviation in the Indicator menu to highlight volume bars that are one or two standard deviations above or below average volume. High volume normally denotes opposition to the current trend and low volume often denotes lack of support for the trend. Volume is especially useful when read in conjunction with the daily candlestick pattern and support/resistance levels.
Default settings are one standard deviation and a moving average of 30 days. Standard colors are red (High volume) and green (Low volume) but can be varied by selecting Format Charts >> Colors >> Indicator Up (+)and Indicator Down (-) on the chart menu.
