分时抓成交量指标通达信指标公式源码```python'''VOLUME_TR=IF(CLOSE>=OPEN,VOLUME,-VOLUME);VOLUME_SUM=SUM(VOLUME_TR,N);VOLUME_MA=MA(VOLUME_TR,M);参数说明：CLOSE:当日收盘价OPEN:当日开盘价VOLUME:当日成交量N:求和周期M:移动平均周期公式说明：VOLUME_TR代表成交力量，如果当日收盘价大于等于开盘价，则为正数，否则为负数；VOLUME_SUM代表N天内的成交力量总和；VOLUME_MA代表N天内成交力量的移动平均值。
'''import talibimport numpy as npdef get_volume_tr(close, open, volume):volume_tr = np.where(close >= open, volume, -volume)return volume_trdef get_volume_sum(volume_tr, n):volume_sum = talib.SUM(volume_tr, n)return volume_sumdef get_volume_ma(volume_tr, m):volume_ma = talib.MA(volume_tr, m)return volume_ma```以上代码是使用Python编写的通达信分时抓成交量指标公式源码，使用了`numpy`和`talib`库来计算一些指标，需要先安装这两个库。
其中，`get_volume_tr`函数计算成交力量，`get_volume_sum`函数计算N天内的成交力量总和，`get_volume_ma`函数计算N天内成交力量的移动平均值。
使用示例：```pythonclose = [10, 12, 11, 13, 12]open = [9, 11, 10, 12, 11]volume = [100, 200, 150, 250, 200]n=3m=5volume_tr = get_volume_tr(close, open, volume)print("成交力量：", volume_tr)volume_sum = get_volume_sum(volume_tr, n)print("N天内的成交力量总和：", volume_sum)volume_ma = get_volume_ma(volume_tr, m)print("N天内成交力量的移动平均值：", volume_ma)```通过输入收盘价、开盘价和成交量数据，即可计算出相应的分时抓成交量指标。

天下无敌分时指标绝无未来函数做T的好帮手通达信指标公式源码天下无敌分时指标（Ultimate Oscillator）是一种常用于市场交易的技术指标，它通过计算市场买卖压力的变化来帮助交易者判断股票或其他资产的趋势和超买超卖情况。
通达信是一个常用的股票分析软件，下面是天下无敌分时指标的通达信指标公式源码：```c/*公式参数*/n:=INPUT(14,"几日买卖压力",1,100,14);//计算周期，默认为14日/*计算公式*/c:=CLOSE;//当日收盘价h:=HHV(HIGH,n);//最近n日的最高价l:=LLV(LOW,n);//最近n日的最低价bp:=SUM(IF(c>REF(c,1),c-l,0),n); // 计算买压sp:=SUM(IF(c<REF(c,1),h-c,0),n); // 计算卖压tr:=SUM(MAX(h-REF(c,1),REF(c,1)-l),n); // 计算真实幅度uo:=100*(bp/tr+2*sp/tr*sp/tr*sp/tr); // 计算天下无敌分时指标/*绘制天下无敌分时指标曲线*/UO:MA(uo,6); // 天下无敌分时指标的6日移动平均线UO1:REFERENCE(UO,1);//上一个天下无敌分时指标的值UO2:REFERENCE(UO,2);//上上一个天下无敌分时指标的值UO3:REFERENCE(UO,3);//上上上一个天下无敌分时指标的值COLOR1:IF(UO>=UO1ANDUO1>=UO2ANDUO2>=UO3,RED,IF(UO<=UO1ANDUO1 <=UO2ANDUO2<=UO3,GREEN,BLUE));//根据天下无敌分时指标的走势给出颜色PLOT(UO,"UO",COLOR1,WIDTHLINE);//绘制天下无敌分时指标曲线图```以上代码中涉及的函数解释如下：-`INPUT`：用于输入需要的参数，这里是计算周期n。

- VAR2代表涨幅天数，表示在过去20个交易日中，VAR1大于等于0的天数。
- VAR3代表跌幅天数，表示在过去20个交易日中，VAR1小于0的天数。
- VAR4代表涨幅均值，表示VAR1在VAR2与VAR3的差值范围内的均值。
- VAR5代表涨幅均值天数，表示在过去20个交易日中，VAR4大于0的天数。
- VAR6代表跌幅均值天数，表示在过去20个交易日中，VAR4小于0的天数。
- VAR7代表跌幅均值，表示VAR4在VAR5与VAR6的差值范围内的均值。
- 分时抓成交量代表指标定义中的公式，根据当前价格与前一天价格的判断，分别计算涨时和跌时的成交量。
- VAR9代表分时抓成交量的20天均值。

分时抓跌幅指标通达信指标公式源码本文档旨在提供使用通达信软件的分时抓跌幅指标的源码公式，以帮助用户在通达信软件中自定义指标并进行相关分析。
一、简介分时抓跌幅指标是一种常用的技术分析指标，旨在捕捉股票价格在交易日内的大跌幅度。
该指标通过计算股票价格在一段时间内的最高价与最低价之差，来衡量价格的波动性和变动幅度。
通过使用该指标，投资者可以更好地掌握股票价格的波动情况，有助于制定交易策略和决策。
二、通达信分时抓跌幅指标公式源码分时抓跌幅指标公式源码代码示例定义输入参数input length = 10.# 计算周期长度input threshold = 5.# 跌幅阈值计算最高价与最低价之差def getRange() {range = high - low;return range;判断是否符合跌幅条件def isFall() {range = getRange();fall = (close - low) / range * 100.# 计算跌幅百分比return fall。
= threshold;主函数def main() {falls = 0;for i = 1 to length {if isFall() {falls = falls + 1;return falls;调用主函数result = main();参数说明length`：计算周期长度，用于计算分时抓跌幅指标，默认值为10.___：跌幅阈值，用于判断是否符合跌幅条件，默认值为5.使用方法1.打开通达信软件，进入【自定义】-【公式】-【新建】，创建一个新的公式。
2.将以上源码复制到新建的公式编辑框中。
3.根据需要，可以修改默认的`length`和___参数值。
4.点击【确定】保存公式并关闭编辑框。
5.在通达信的相应图表中，添加刚刚创建的分时抓跌幅指标公式。
6.根据公式计算结果，分析股票价格的分时抓跌幅情况。
注意事项以上示例代码为通达信软件中的公式编写，仅供参考和研究使用。
