An Elliott Wave impulse is a trend move made of five waves: in a downtrend, three declines (waves 1, 3 and 5) separated by two rebounds (waves 2 and 4). This screen lists stocks on the London Stock Exchange that have completed a 5-wave down impulse over the last 128 bars, with wave 5 ending within the last 7 bars and still the lowest close since wave 4. The count follows the core Elliott rules on closing prices: wave 2 never rises above the start of wave 1, wave 4 stays below the bottom of wave 1, wave 3 is not the shortest of the three declining waves, and wave 5 ends below wave 3. Wave 1 must start from at least a 64-bar high, swing points are confirmed by 7 bars on each side, and charts with a gap of more than 20% are skipped. A completed fifth wave down often marks the late stage of a decline, so traders watch for an A-B-C rebound and a possible bottom. Because these signals are rare, the list includes all stocks on the London Stock Exchange, with no price or liquidity filter.
