Handling CTRL-C when trading live

holicst

Hi Everybody, dear @backtrader,

I’d like to handle CTRL-C (SIGINT) when trading Live. In this case I’d like to trigger method runstop(), and in the stop() method I want to save the statistics of my trading to a DB. I googled this and added the recommended code:

    def next(self, frompre=False):

        try:
		...business logic here...
        except KeyboardInterrupt:
            self.log('CTRL-C detected - stopping')
            self.stopped=True
            self.env.runstop()
            return

However, this does not work apparently:

How can I achieve the goal to be able to stop a live trading and in that moment save everything to the DB?

Thanks and best regards,
