What is repaint mean?

 

I don't quite understand it's mean when we talk about indiater like solar wind or other indicater,anybody can explain it to me,thx a lot~

 
Repaint means what the Indicator shows Now is not Exactly what it showed in Real-Time or when it was running Live. Example, the High -Price you see on the current Bar/Candle may NOT be the same when the Bar/Candle Closes. Here another attempt at defining it https://www.mql5.com/en/forum/130370.
