20-Day Rolling Low Follow-Up Strategy

This scanner identifies stocks that have made a significant short-term low within the last 20 trading days and are showing bullish follow-through. It is designed to catch stocks that bounce off support after forming a meaningful low.

The strategy uses the following conditions:

• 20-day rolling low
  For each stock, the scanner calculates the lowest price over the last 20 days. A day is marked as a 20-day low if its low equals or falls below this value.
• Gap between lows
  The system requires at least 4 days since the previous 20-day low to avoid clustering of signals.
• Bullish follow-through
  The next day's close must be higher than the low day. This confirms that buyers stepped in and validates the low as a meaningful support level.
• Yesterday’s signal
  Only the previous day's 20-day low is considered. The signal is confirmed if today's close validates the bullish follow-through conditions.

This strategy helps traders identify stocks that are stabilizing after a short-term decline and are beginning to show upward momentum. It can be used for short-term swing trading or to time entries after a pullback.
