I was defining a function Heiken Ashi which is one of the popular chart type in Technical Analysis. I was writing a function on it using Pandas but finding little difficulty. T
Perfectly working HekinAshi function. I am not the original author of this code. I found this on Github (https://github.com/emreturan/heikin-ashi/blob/master/heikin_ashi.py)
def heikin_ashi(df):
heikin_ashi_df = pd.DataFrame(index=df.index.values, columns=['open', 'high', 'low', 'close'])
heikin_ashi_df['close'] = (df['open'] + df['high'] + df['low'] + df['close']) / 4
for i in range(len(df)):
if i == 0:
heikin_ashi_df.iat[0, 0] = df['open'].iloc[0]
else:
heikin_ashi_df.iat[i, 0] = (heikin_ashi_df.iat[i-1, 0] + heikin_ashi_df.iat[i-1, 3]) / 2
heikin_ashi_df['high'] = heikin_ashi_df.loc[:, ['open', 'close']].join(df['high']).max(axis=1)
heikin_ashi_df['low'] = heikin_ashi_df.loc[:, ['open', 'close']].join(df['low']).min(axis=1)
return heikin_ashi_df
