Bollinger with line zero

The Macd Cross Zero Arrow indicator draws buy and sell signals based on the intersection of the MACD indicator lines with the zero line. For example, when the histogram of the indicator crosses the zero line upwards, a buy signal appears with the candle's close, and when the histogram of the indicator crosses the zero line downwards, a sell signal appears with the candle's close.Indicator Features:Setting the working time of the expert.Ability to control MACD indicator settings.Indicator Settings:MacdSMA, SlowEMA, FastEMA: MACD indicator settings.Enable_Alert: Activate the alert feature with a sound message.
