成交量指标可以用来突出证券的不寻常交易活动。它能够在一个单独的窗口中显示出日、周或月交易量细节图。
示例
可口可乐公司股价的调整期对应的日成交量图以及5日EMA。
上图中的[1] 到 [4]处可以看到成交量增长迅速。前三处成交量的迅速增长是在收盘价接近最高价时，表明价格集聚（买方压力）。[4] 处收盘价接近于价格的低点，预示着价格分散（卖方压力）。[5] 处的低成交量说明趋势的不确定性，但是接下来成交量的增长以及收盘价的升高，说明价格集聚。
设置
1. 打开技术指标设置窗口
2. 在左侧选择“volume”
3. 在下侧的 Optional Indicator Smoothing, 设置移动平均线
(上述例子中设置的是成交量的5日EMA。)
4. [>] 保存参数设置
5. [x] 关闭技术指标设置窗口
成交量指标的颜色
在技术指标菜单中选择 Volume With Close color ，这样你就可以根据成交量柱状图的颜色来判断收盘价上升或者升高。
成交量柱状图的默认颜色是绿色（收盘价上升）、红色（收盘价下降）。你可以在图表菜单中更改默认设置：Format Charts >> Colors >> Indicator Up (+) and Indicator Down (-)
成交量的标准偏差
成交量指标柱状图偏于繁杂，因此，我更倾向于使用成交量的标准偏差来突出显示那些不同寻常的成交量（成交量高于或低于平时成交量的1~2倍标准偏差）。较高的成交量通常预示着当前趋势的反转，而较低的成交量则说明当前趋势缺乏动力。成交量指标结合日蜡烛图、支撑阻力位使用，会产生良好的效果。
默认设置是1倍标准方差以及30日MA.高成交量的默认颜色为红色，低成交量为绿色。但是你也可以通过图表菜单中的Format Charts >> Colors >> Indicator Up (+)and Indicator Down (-) 更改颜色设置。
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.
