Python計算KDJ值

Python計算KDJ值，但計算的結果跟通達信軟件有一定的差別。

import talib as ta
import tushare as ts
import pandas as pd
dw = ts.get_k_data("601069")
print(dw)
dw = dw[60:]
dw.index = range(len(dw))
dw['slowk'], dw['slowd']  = ta.STOCH(dw['high'].values, dw['low'].values, dw['close'].values, fastk_period=9, slowk_period=3, slowk_matype=1, slowd_period=3, slowd_matype=1)
df = pd.DataFrame(data=dw)
row = df.iloc[-10:].values
print(row)
