This indicator can be used as an alarm for MACD crossing and uses EMA to distinguish the quality of alerts. Buy1 and Sell1 are crossings outside the EMA and the color is brighter, the rest of the cross is darker. If u don't want to distinguish alerts, u can use the original Adjustable MACD Alert as following. https://www.tradingview.com/script/QQfQnhL9-Adjustable-MACD-Alert/
