I'm still testing the VQ indicator but it seems that:

when realtime=true and TimeFrame=0, it can repaint until current candle closes, and

when realtime=true and TimeFrame=non-zero, then it can repaint until the candle of the TimeFrame closes.

When realtime=false, my guess is that it would not repaint but I had an impression that it does not refresh properly having to refresh manually by opening and closing property window.

On a side note, it seems the indicator has a bug. Here's what I see:

When 2 signals in a row get canceled by adverse price moves, it fails to put SignalPrice text (the "arrow" with price level) , and it also fails to alert the signal.
Have anyone experienced something like that?

Edit: The above case is for when RealTime=true.
