Is there a way to stop an live trading algorithm if certain condition met?
def before_trading_start(context, data):  
    if something condition met:  
        stop algorithm running  
    return

It could be to check if the fetcher fails, stop algorithm from running. Any ideas?

I guess i am asking stupid question here. I thought the trading actions can be easily controlled by global variable values.

To stop an algorithm using code, there isn't a graceful, designed API. But if you throw an exception, you'll get the desired effect! The algo will stop running and you will get an email saying an exception occurred.
