Average Price between Two Points

Script calculates & displays the average price of two selected points. Request from @Bosstradamus3 on Twitter.
This is a quick & dirty script that should be updated in the future.
If you use it and/or modify it, I'd love to hear about it.

Once the indicator is selected, click & drag the label base to reset starting & ending points.
To display label on top of bars, right click on it & select "Visual Order" → "Move to Front."
