This screen finds stocks whose MACD histogram is below zero. The MACD Histogram(12,26,9) plots the difference between the MACD line and its 9-day signal line, so it crosses zero exactly when the MACD crosses its signal line and shows whether momentum is speeding up or slowing down. Negative bars mean the MACD is below its signal line; growing bars show accelerating downside momentum, shrinking bars a decline that is losing speed.
