Large volume indicator to show the price above/below

Large volume is meaningful that usually the current price above the highest price of the bars with largest volume usually means uptrend in the short-term.
In the opposite, below it means downtrend.
I coded this indicator to save the efforts to compare it, make it easily to tell the uptrend/downtrend by above/below and color.
Hope you guys enjoy it, and welcome to comment.

The Inputs:
Length:the largest volume of bars of the total bars numbers.
Color:the above/below colors.
Text:Remind this line is large volume R/S.

You can find the video tutorial in my ideas sharing.
