Arrow not printing after the line cross

[aksofficial]

Hi team, I got a custom code. The arrow seems to follow the next candle open and it will not reflect after the 2 MA cross correctly without me refreshing the chart. PLease advise how to fix this thank you!!

Try to add ChartRedraw() operation in the end of your code.

Like this....

   
   ChartRedraw();
   //----
   return(rates_total);
  }

Thank you for helping! 

However, the issue is the same..when the MA cross each other it shows a red arrow on the current candle even if it's in an upward direction and I still need to manually refresh to get the arrow.
