In the Wyckoff method a spring is the final shakeout of an accumulation range: price dips below support, flushes out weak holders and quickly returns into the range. This screen lists stocks on the London Stock Exchange where a bear trap has formed on the support lines of the SNR indicator (fractal-based support and resistance) with volume above its 21-day average. Traders treat a spring as a potential low-risk entry with a stop below the shakeout low. LSE prices are quoted in pence, and the list skips thinly traded shares.
