Resistance Breakout
Breakouts of significant resistances often produce the most explosive moves. Low win rate but very high R/R — just one trade out of three hitting target is enough to be overall profitable.

When an important resistance is tested multiple times and then broken with force and volume, traders who had short positions get liquidated (short squeeze), traders who were waiting for the breakout enter, and buyers from below add positions. This creates a 'wall of buyers' that pushes price violently upward.
