Profits of US$462.50 after 30 minutes of trade entry

Below is a screen capture from one of my student who only trades Futures. He posted this screen capture into my private student’s smartphone chat group yesterday on 17th August after I mentioned to the group that I see the S&P Futures going up for the day and he traded it. I was very happy for him as that one trade only lasted around 30 minutes and he made US$462.50 in that one trade.
