What is a long squeeze?
A sharp price drop driven by forced selling: longs get liquidated, and their sell orders push the price lower.
It is the mirror image of a short squeeze. When the price falls, overleveraged longs hit their liquidation price and are closed with market sells, which pushes the price to the next cluster of longs.
Warning signs: a high positive funding rate, growing open interest and large long clusters just below the price.
