現在讓我們創建數據框:
df = DataFrame(data=p, index=i, columns=['price'])
看起來什麼數據,如針對分鐘03:54
:
df[df.index >= Timestamp('2015-10-07 03:54:00+00:00')].head(12)
price
2015-10-07 03:54:02.648000+00:00 1965.00
2015-10-07 03:54:02.648000+00:00 1965.00
2015-10-07 03:54:02.648000+00:00 1965.00
2015-10-07 03:54:02.648000+00:00 1965.00
2015-10-07 03:54:02.648000+00:00 1965.00
2015-10-07 03:54:02.648000+00:00 1965.00
2015-10-07 03:54:02.648000+00:00 1964.75
2015-10-07 03:54:02.648000+00:00 1964.75
2015-10-07 03:54:02.648000+00:00 1964.75
2015-10-07 03:54:02.648000+00:00 1964.75
2015-10-07 03:54:04.268000+00:00 1964.75
2015-10-07 03:54:04.268000+00:00 1964.75
第一個價格是1965.00
。現在,讓我們用大熊貓resample
方法創建1分鐘吧:
df.resample(rule='1Min', how='ohlc', closed='left', label='left')
price
open high low close
2015-10-07 03:50:00+00:00 1965.25 1965.75 1965.25 1965.50
2015-10-07 03:51:00+00:00 1965.75 1965.75 1965.25 1965.50
2015-10-07 03:52:00+00:00 1965.75 1965.75 1965.25 1965.75
2015-10-07 03:53:00+00:00 1965.50 1965.75 1965.25 1965.50
2015-10-07 03:54:00+00:00 1964.75 1965.25 1964.50 1965.25
開市價爲1964.75
當它應該是1965.00
在03:54
。
添加行列顯示問題完美:
df['row'] = range(1, df.shape[0] + 1)
grouped = df.groupby(TimeGrouper(freq='1Min', closed='left', label='left'))
grouped.get_group(Timestamp('2015-10-07 03:54:00+00:00')).head(12)
price row
2015-10-07 03:54:02.648000+00:00 1964.75 189
2015-10-07 03:54:02.648000+00:00 1964.75 188
2015-10-07 03:54:02.648000+00:00 1964.75 187
2015-10-07 03:54:02.648000+00:00 1964.75 186
2015-10-07 03:54:02.648000+00:00 1965.00 185
2015-10-07 03:54:02.648000+00:00 1965.00 181
2015-10-07 03:54:02.648000+00:00 1965.00 183
2015-10-07 03:54:02.648000+00:00 1965.00 182
2015-10-07 03:54:02.648000+00:00 1965.00 180
2015-10-07 03:54:02.648000+00:00 1965.00 184
2015-10-07 03:54:04.268000+00:00 1964.75 190
2015-10-07 03:54:04.268000+00:00 1964.75 191
時的時間戳是相同的類TimeGrouper
改變行的順序。
臨時解決方案是在應用ohlc
轉換之前按行列對每個組進行排序。
感謝您的關注!
大熊貓的什麼版本?爲什麼不使用OHLC方法... –
熊貓版本16.2 與OHLC相同的問題: x ['price']。resample('1Min',closed ='left',label ='left',how ='ohlc ') 2015-10-07 03:54:00 + 00:00 1964.75 1965.50 1964.50 1965.25 – agiap
我不相信所有的熊貓都必須穩定,所以我猜想resample會做一些不穩定的排序?如果是這樣,我想你會需要做一些類似於你所做的事情,並在一些獨特的列上手動排序。 – JohnE
