Jim,
This code does exactly what you want. You may want to modify it a bit.
If the volume is more than twice the average vol, it reduces it to the
average volume and paints it yellow.
You can substitute any height you want instead of avg volume.
About the peak you want to reach the top, it will depend on the remaining
bars ...if it's the highest it will go to top.
