#### 威廉指标定义 ``` def WR(price, N=21, N1=42): #W&R 威廉指标 CLOSE = price['close'] HIGH = price['high'] LOW = price['low'] WR = (HHV(HIGH, N) - CLOSE) / (HHV(HIGH, N) - LLV(LOW, N)) * 100 WR1 = (HHV(HIGH, N1) - CLOSE) / (HHV(HIGH, N1) - LLV(LOW, N1)) * 100 return RD(list(WR)), RD(list(WR1)) ``` #### 使用 ``` prices_day = get_bars(stock, 300, '1d', fields=['open','high','low','close'],fq_ref_date=None, df=True) # 日线WR指标 WR1_day, WR2_day = WR(prices_day) ``` ##### 结果 ###### 使用 600475.XSHG 跑结果发现： 2023-06-19 09:00:00 - INFO - WR1_day[-1]:74.272 2023-06-19 09:00:00 - INFO - WR2_day[-1]:76.233 2023-06-19 09:00:00 - INFO - WR1_day[-2]:88.35 2023-06-19 09:00:00 - INFO - WR2_day[-2]:89.238 ###### 同花顺的值 WR1_day[-1]:69.01 WR2_day[-1]:60.81 WR1_day[-2]:85.96 WR2_day[-2]:73.87
