I read the code about backtrader/utils/autodict/AutoDict,but find something maybe wrong...

[tianjixuetu]

class AutoDict(dict):
    
    _closed = False

    def _close(self):
        self._closed = True
        for key, val in self.items():
            if isinstance(val, (AutoDict, AutoOrderedDict)):
                val._close()

    def _open(self):
        self._closed = False

    def __missing__(self, key):
        
        if self._closed:
            raise KeyError

        value = self[key] = AutoDict()
        return value

    def __getattr__(self, key):
        
        if False and key.startswith('_'):
            raise AttributeError

        return self[key]

    def __setattr__(self, key, value):
        
        if False and key.startswith('_'):
            self.__dict__[key] = value
            return

        self[key] = value

your code about : if False and some_code: do something
I think ,it will never run do something.

mybe you just want write this code.
mybe,you should replace "False" with "self._closed", I guess.

I have used backtrader for more than one year to backtest my strategy, I also find many errors, so,I have to read the source code,to understand backtrader's framework and details.

Anyway, thank you！

It's code that was tested for development and considered, was left there but nullified.

Which you of course duly reported.
