Hi guys,

I'm coding on a t2.micro instance on AWS ec2 running on Amazon Linux 2 os. I built a strategy with 2 data feeds and everything works well but when I try to plot it, my jupyter notebook kernel stay busy forever... I cant even stop jupyter, I have to close the cmd and reboot my instance in order to use it again.

Anyone faced the same issue or have a solution?

Thanks,
Antoine

@kaber-mobile Hi, I may have a few question as I am trying to develop an algo trading system for crypto based on ML. How can I contact you?

Maybe this will help someone... I had the same issue and solved it by using a percentage of my portfolio

class Antoine_sizer(bt.Sizer):
    params = (('prop', 0.1),)

def _getsizing(self, comminfo, cash, data, isbuy):
    """Returns the proper sizing"""

    if isbuy:    # Buying
        target = self.broker.getvalue() * self.params.prop    # Ideal total value of the position
        price = data.close[0]
        size_net = target / price    # How many shares are needed to get target
        size = size_net * 0.99

        if size * price > cash:
            return 0    # Not enough money for this trade
        else:
            return size

    else:    # Selling
        return self.broker.getposition(data).size    # Clear the position
