This screen finds stocks whose RSI has been falling for the last 3 days. The RSI(14), developed by J. Welles Wilder, compares average gains with average losses over 14 days on a scale from 0 to 100; readings above 70 are considered overbought, below 30 oversold, and 50 separates bullish from bearish momentum. A steadily falling RSI shows building selling momentum; over a few days it can signal a fresh pullback, while over weeks it describes a persistent decline.
