Problem with attribute 'Rebalance' in my strategy

Based on the error message you provided, it seems like you're trying to call a method named 'Rebalance' that doesn't exist in your 'MyAlgorithm' class. This could be due to a typo in the method name or the method might not have been defined at all.

You should define a method named 'Rebalance' in your 'MyAlgorithm' class. Here is a simple example of how you might define it:

class MyAlgorithm(QCAlgorithm):
    def Initialize(self):
        # Initialization code here
        self.Schedule.On(self.DateRules.EveryDay(), self.TimeRules.At(0, 0), self.Rebalance)

    def Rebalance(self):
        # Rebalancing code here

In this example, the 'Rebalance' method is called every day at midnight. You would replace the comment with the actual code you want to execute during the rebalance.

If you've already defined the 'Rebalance' method, make sure that it's spelled correctly and that it's properly indented to be part of the 'MyAlgorithm' class. Python is case-sensitive and uses indentation to determine the structure of the code, so a mistake in either of these areas could cause the method to not be recognized.
