This screen lists stocks on the London Stock Exchange where the MACD line (12, 26) crossed above the zero line on the latest bar. MACD above zero means the 12-period EMA has moved above the 26-period EMA, so the cross confirms that the short-term trend has turned up. It comes later than a signal-line crossover but gives fewer false signals. LSE prices are quoted in pence, and the list skips thinly traded shares.
