peil wasn't entirely wrong. there WAS a shorting opportunity, i made a cool 10% on the short side last week. the mistake, as usual, is timing.
when you see retail traders piling onto a stock, it's usually a good indication to start going the other way because there's going to be somebody big on the sidelines waiting to trigger a squeeze.
finally, on a day like today, information is key. being able to see the sizes of the bid/asks as they are entered and pulled, the size of the books on both sides, and the volume of each move. i was reading all this off a QuantQuote feed I have set to print to screen, that's how i noticed the support at $20 a couple minutes prior to the squeeze.
