Is there any software or website that can detect sudden opportunity in during live market

For on July 18th 2018 (yesterday) there was sudden fall in index, during which I could buy put option 11200 and made good amount of money …but I am watching index every minute so wondering if there is any tool that can detect such change and place a bet on its own or send an alert to cell phone?
