'TradeBar' object has no attribute 'IsReady'

The error message you're seeing is indicating that the 'TradeBar' object does not have an 'IsReady' attribute. The 'TradeBar' object has the following attributes: Open, High, Low, Close, Volume, Time, EndTime, and Symbol.

The 'IsReady' attribute is typically used with indicators to check if the indicator is ready to be used (i.e., it has received enough data points to start producing accurate values). If you're trying to check if the 'TradeBar' data is ready, you might want to check if the 'TradeBar' object is not None instead.

Here's an example of how you can do this:

def OnData(self, data):
    if data.ContainsKey(self.symbol):
        tradeBar = data[self.symbol]
        if tradeBar is not None:
            # Your code here

This code checks if the 'TradeBar' data for the given symbol exists in the 'data' object, and if it does, it assigns the 'TradeBar' data to the 'tradeBar' variable. Then it checks if 'tradeBar' is not None before proceeding with the rest of the code. This ensures that the 'TradeBar' data is ready to be used.

Please revise your code accordingly. If you continue to have issues, please provide more specific details about the problems you are encountering.
