How to include minute of the trading day on each log line

Tools and Tips

For prefacing log lines with the minute of each day. I find this useful sometimes, easier to read than the time stamps.

from pytz import timezone as tz

def minut():           # Minute of the trading day  
    dt = get_datetime().astimezone(tz('US/Eastern'))  
    return (dt.hour * 60) + dt.minute - 570

Examples:

log.info('{} {}'.format(minut(), int(context.portfolio.portfolio_value)))
