For this position, he has 100 0 day to expiration puts that he bought for $62 each. Spy tanked making each contract worth $138. 

No reasonable person will recommend you follow suite with 0 day to expiration options. What op isn't showing you is that spy rallied to close at $383 today, making these worthless if he held and didn't sell.

From the day profit that op posted, it looks like he took some winnings today, but left this position open to see where it goes. Every dollar spy falls would have been $10,000 profit. Instead it rallied so it's unlikely that op closed above 100k.

I use the term "winnings" rather than earnings because this was a $6200 bet that happened to work out. It very well could have been worthless in a matter of minutes.

Check my update below. I sold at 1.6 and I think the high today was 1.8ish. Got out almost perfect timing.
