Fixed a bug in showing new divergences and indicator alerts.
Minor adjustment and improvements.

+ A new confirmation type added to the indicator: MACD Cross Signal Line.
+ Indicator performance improved.

+ Two confirmation type added to indicator (MACD cross zero level, Price Returns to Previous H/L).
+ For new confirmation types, when divergence confirms, the indicator shows an arrow on the chart.
+ For reducing the indicator's resource usage, now you can set to apply the indicator on how many number of candles.
