We capture pre-breakout early signals,
not after a surge
The DawnScan scanner is not a service that alerts you to stocks that have already surged. It detects technical preparation signals that appear before price moves significantly. This page transparently explains what signals the scanner looks at, how it filters stocks, and what criteria it uses to score hit rate.
Most stock recommendation alerts arrive after stock prices have already risen significantly. Chasing buys carries high volatility and downside risk. This scanner detects the preparation phase before a price surge occurs—the phase where buy-side volume begins to build (buyer identity is not determined) or volatility contracts right before an explosion.
Each pattern is meaningful on its own, but the higher the score becomes when multiple signals appear simultaneously. The scanner tracks the base rate and lift for 32 signals, including the patterns below, and measures and publishes daily whether each signal has actually beaten the base rate. (The 32 tracked signals and the 49 conditions that actually feed the score are ★not the same list — most of the tracked 32 are observation/testing only and don't feed the score itself.)
Every day, all US NASDAQ and NYSE stocks (about 6,000) are compressed through two stages. Stocks that fail to pass each stage are excluded from the results.
The core question of the 'pre-breakout early signal scanner' is just one — "Did the stock price actually rise after selection?" Scan results are recorded daily based on the criteria below, and post-performance is automatically tracked.
