Channel Pattern Screener — Support & Resistance Breakout Detection
Detects stocks trading in well-defined channels between parallel support and resistance lines. Price must have touched both the channel floor and ceiling at least 3 times. Filters for market cap above $300M, average volume above 500K, and excludes biotech penny stocks.
Entry: Channel Floor Bounce
When price touches the channel bottom and shows a bullish reversal candle (hammer, engulfing, or doji), enter long. Target is the channel ceiling. Stop loss sits just below the channel floor.

Exit: Channel Ceiling or Breakout
Take profits at the channel resistance level. If price breaks above the ceiling on above-average volume, the stock is transitioning to an uptrend — hold with a trailing ATR stop instead of selling at resistance.

Quality Filters
Only stocks with market cap >$300M and average daily volume >500K are included. Biotech and penny stocks are excluded to avoid low-liquidity traps. This keeps the screener focused on tradable, liquid names.

Regression Channel Screener
A second screener on the same page fits a least-squares regression line through log price over two years across the whole US common-stock universe, then keeps the names whose trend is shallow and steady and whose price never strays far from that line.
Log-Price Regression Fit
Because the fit runs through the logarithm of price, the trend is measured as a constant compounding rate rather than dollars per day, and the channel walls are exponential curves that widen with price. Qualifying names hold a 0–3 degree slope with price staying within roughly 10% of the fitted line.

Nightly Full-Market Refit
Every channel is refitted overnight across roughly 5,000 US common stocks, then prices and trade levels refresh hourly. Because the band slopes upward with the trend, entry, stop and target all walk higher as the channel ages.
