这是L大师用python计算dmi的函数,但与vba直接写的函数计算的结果有区别,具体内容如下:
def GetAdx(bar_data, dm_n=14, ma_n=6):
high = list(bar_data['high'])
low = list(bar_data['low'])
close = list(bar_data['close'])
idx = bar_data.index
dmp, dmm, tr, adx = map(list, [[], [], [], []])
t = 0
for d in range(len(idx)):
hl = abs(high[d] - low[d-1])
hc = abs(high[d] - close[d-1])
lc = abs(low[d] - close[d-1])
hd = high[d] - high[d-1]
ld = low[d-1] - low[d]
dmp.append(hd if hd > 0 and hd > ld else 0)
dmm.append(ld if ld > 0 and ld > hd else 0)
tr.append(max(hl, hc, lc))
t += 1
if t > dm_n:
dmp.pop(0)
dmm.pop(0)
tr.pop(0)
t -= 1
#print(t)
if t == dm_n:
if sum(tr) != 0:
pdi = sum(dmp) * 100 / sum(tr)
mdi = sum(dmm) * 100 / sum(tr)
if mdi + pdi != 0:
adx.append(abs(mdi - pdi) / (mdi + pdi) * 100)
else:
adx.append(0)
else:
adx.append(0)
if len(adx) > ma_n:
adx.pop(0)
bar_data.loc[idx[d], 'ADX'] = sum(adx)/ma_n
bar_data.loc[idx[d], 'ADXR'] = (sum(adx)/ma_n + bar_data.loc[idx[d-1], 'ADX']) / 2

计算结果如下,修改python函数能做到一致吗?
