    # 创建5分钟K线合成器
    self.bg5 = BarGenerator(

    )
    self.am5 = ArrayManager(size=100)  # 使用ArrayManager管理5分钟K线

tempam

    tempam = self.am5

    if self.bg5.bar is not None:
        tempam.append(self.bg5.bar)

================爆错。。。
~~~^^^^^^^^^^
File ""D:\VeighNa_Studio\Lib\site-packages\vnpy_ctastrategy\strategies\my_strategy.py"", line 84, in on_bar
tempam.append(self.bg5.bar)
^^^^^^^^^^^^^
AttributeError: 'ArrayManager' object has no attribute 'append'

已解决，谢谢！
