Here is the modified revision to allow user to enter aggregation time frame

# Script Name: Buy & Sell Volume Avg & Pressure
# Author: Denver Stair
# 2/15/2026
# Version 1.2
# Revision: Updated to allow user to select aggregation period time frame

#wizard input: Show_Arrows
#wizard text: Inputs: B/S Arrows
#Hint: This Study displays the approximate current candle buy, sell, and total volume, (added an input if you would like to see premarket volume as well) for current time frame. It also plots the approximate volume values for the total volume | average volume | approx sell volume | and aprox buy volume of timeframe under cursor. Note: If the result returns N/A the high = close or low = close and time frame is a doji. Choose your inputs to see premarket, total volume, and day market total volume. There are also arrow indicators based on VWAP for enter and exit points. The volume histogram always shows the dominant value in back and lowest volume in front.
