Support Break
Support and resistance levels are horizontal lines on a chart that represent price levels where the market has previously struggled to move beyond. Support is a level at which buying interest is strong enough to prevent the price from falling further, while resistance is a level where selling pressure is strong enough to prevent the price from rising further. A breakout above a resistance level or below a support level can signal a significant shift in market sentiment. However, false breakouts can occur, so it's important to confirm the breakout with additional indicators or price action.
Across 53 scored detections, the Support Break moved the way it predicts relative to SPY 51% of the time over the next 20 trading days, with a mean excess return of -1.85%. A coin flip scores about 50%.

Win rate = share of occurrences where the stock beat SPY over the window in the direction the signal predicted — for a bearish setup, a win means it underperformed. Measured on our own detections, which puts the coin-flip line at 50%. Sample sizes are small; treat these as context, not as an edge.
