取得日线和4H历史资料
2个不同shape的Series怎么做操作
print(ohlcv_D.close.shape) #(1517,)
print(ohlcv.close.shape) #(36257,)
想把他加到
entries = crossover(macdhist, 0) &
(ohlcv_D.close.shift(1)>ohlcv_D.close.shift(2))
会出现ValueError: shape mismatch: objects cannot be broadcast to a single
shape
ohlcv_D

应该是crossover function出来的大小跟要AND的大于结果不一样 这边要检查

index都已是time series把1D upsampling成4Hohlcv_D.resample("4H").ffill()看错了QQ，我的方法不行

谢谢回答 答案是用reindex(index=ohlcv.index, method='ffill
