You're right - you don't know who will win. But the math will tell you which has a better chance. I prefer to have statistics / probabilities on my side.
After all - this is a game of math apart from the psych.
Yeah, exactly market could dump 100 points here in a minute, but it's still less probability over time to short moves like this (particularly if looking for anything more than a scalp or small to at best medium size down move).
For me no shorts today, either long or flat only options I am using today.
