SUM(xx,0)，求所有xx的累加和。这个怎么改下呀？会出错。 比如LON长线指标，这个SUM(RC,0)会出错。改成具体的数字出来的值不对。改成len(RC)，倒数第二个值为0了。 LC := REF(CLOSE,1); VID := SUM(VOL,2)/(((HHV(HIGH,2)-LLV(LOW,2)))*100); RC := (CLOSE-LC)*VID; LONG := SUM(RC,0); DIFF := SMA(LONG,10,1); DEA := SMA(LONG,20,1); LON : DIFF-DEA; LONMA : MA(LON,N); LONT : LON, COLORSTICK;

@DreamHigh ok

这个必须先赞再学习呀

这下厉害了，打通了任督二脉？

学习一下

不错的福利 谢谢

感谢作者分享！

厉害，学习了！

能加微信么？帮忙改个通达信公式。

通达信里的hhv 和ref 嵌套的话会有bug

麻烦看一下这是什么原因： step1: 设置时间 set_current_date('2020-03-07 15:57:00') step2: win_size，取多少天的数据，如果要做MACD计算，建议取120天，别的根据HHV/LLV/REF等函数的参数来决定 set_count(20) step3: 1d/5m/1m set_current_freq('1m') step4: 选择某只stock做运算 S('002345.XSHE') step5: 直接写技术公式并获得结果，熟悉的味道 print(MA(C,5), REF(MA(C,5), 1), MA(C,10), REF(MA(C,10), 2)) print(MA(C,5)) StopIteration Traceback (most recent call last) /opt/conda/lib/python3.6/site-packages/talib/init.py in wrapper(args, *kwargs) 19 index = next(arg.index ---> 20 for arg in chain(args, kwargs.values()) 21 if isinstance(arg, _pd_Series)) StopIteration: During handling of the above exception, another exception occurred: Exception Traceback (most recent call last) ~/funcatjq.py in _init(self, series, arg) 735 series[series == np.inf] = np.nan --> 736 series = self.func(series, arg) 737 series = filter_begin_nan(series) ~/funcat_jq.py in func(self, series, n) 748 def func(self, series, n): --> 749 return talib.MA(series, n) 750 /opt/conda/lib/python3.6/site-packages/talib/init.py in wrapper(args, **kwargs) 23 # No pandas.Series passed in; short-circuit ---> 24 return func(args, **kwargs) 25 talib/_func.pxi in talib._ta_lib.MA() Exception: inputs are all NaN During handling of the above exception, another exception occurred: FormulaException Traceback (most recent call last) < ipython-input-1-02eeaa932718> in < module> 15 # step5: 直接写技术公式并获得结果，熟悉的味道 16 #print(MA(C,5), REF(MA(C,5), 1), MA(C,10), REF(MA(C,10), 2)) ---> 17 print(MA(C,5)) ~/funcatjq.py in init(self, series, arg) 737 series = filterbegin_nan(series) 738 except Exception as e: --> 739 raise FormulaException(e) 740 super(OneArgumentSeries, self).__init(series) 741 self.extra_create_kwargs["arg"] = arg FormulaException: inputs are all NaN

这个怎么用啊Python小白正在学习能否简单叙述一下使用过程十分感谢

请问wrapperBARSLAST在哪定义？ Traceback (most recent call last): File "/tmp/jqcore/jqboson/jqboson/plugin/web.py", line 83, in import_ return self._builtin_import(name, *args, **kwargs) File "./funcat_jq.py", line 479, in < module> class TimeSeries(object): File "./funcat_jq.py", line 489, in TimeSeries @wrap_formula_exc File "./funcat_jq.py", line 44, in wrap_formula_exc return wrapperBARSLAST NameError: name 'wrapperBARSLAST' is not defined

@MR.叉烧 大佬运行成功了么 ，我运行遇到问题NameError Traceback (most recent call last) < ipython-input-3-ed0a8fd6d0ff> in < module> 68 69 if __name__ == '__main__': ---> 70 set_current_date('2021-08-06 14:57:00') 71 set_count(100) 72 set_current_freq('1d') NameError: name 'set_current_date' is not defined

funcat里面没有HHVBARS和LLVBARS，楼主能否确认下？谢谢。
