问题描述
我有一个1分钟的酒吧OHLC价格CSV文件,我正尝试将其重新采样到15分钟的酒吧.我正在使用的代码来自以下链接,如下:
I have a 1-Minute bar OHLC price CSV file that I am trying to resample to 15-Minute bars. The code that I am using is from this link, and is follows:
ohlc_dict = {'open':'first', 'high':'max', 'low':'min', 'close': 'last'}
price15m = df.resample('15Min', how=ohlc_dict, closed='right').dropna(how='any')
我正在获得预期的重采样数据帧,但此警告也是如此:
I am getting the expected resample dataframe, but this warning too:
FutureWarning: how in .resample() is deprecated
the new syntax is .resample(...)..apply(<func>)
ohlc_dict = {'open':'first', 'high':'max', 'low':'min', 'close': 'last'}
建议使用此语法,但我不确定如何:
The suggestion is to use this syntax but I am not sure how to:
the new syntax is .resample(...)..apply(<func>)
有人可以指出我正确的方向吗?非常感谢!
Can someone point me in the right direction? Thanks very much!
推荐答案
You can use Resampler.agg
:
price15m = df.resample('15Min', closed='right').agg(ohlc_dict).dropna(how='any')
