Recently, NTB crossed above the 20-day moving average, suggesting a short-term bullish trend.The 20-day simple moving average is a well-liked trading tool because it provides a look back at a stock's price over a 20-day period. Additionally, short-term traders find this SMA very beneficial, as it smooths out short-term price trends and shows more trend reversal signals than longer-term moving averages.The 20-day moving average can show signals that are similar to other SMAs as well.
