order.ref keeps increasing after new cerebro instantiation
I am a new backtrader user and I really love it so far. Thanks for this awesome piece of software. One thing I noticed though, was that the order reference always keeps increasing, even after creating a new cerebro instance.
Concretely, I have a function that calculates a portfolio performance, given some input assets. This function is called in a loop. Every function call should create a new cerebro instance, yet the order reference always keeps increasing. Is this expected behavior and why?
The program looks like the following:
def calculate_performance(assets, start, end): cerebro = bt.Cerebro() ... results = cerebro.run() return cerebro.broker.getvalue() if __name__ == "__main__": for assets in asset_list: ending_value = calculate_performance(assets, start, end)
Thanks a lot in advance!
Because you are in a single Python script.
