The issue here is that the TimeGrouper class sorts the timestamps in a specific way when creating groups, which can lead to incorrect results for certain use cases. A temporary solution could be to reset the index of the dataframe before resampling, so that each group has consecutive indices: df = DataFrame(data=p, index=i, columns=['price']) df['row'] = range(1, df.shape[0] + 1) grouped = df.groupby(TimeGrouper(freq='1Min', closed='left', label='left')) for name, group in grouped: group.

Replacing Data in a Table Using SQL In this article, we will explore the process of replacing data in one table using data from another table.
