The following ProBuilder code snippet is designed to draw rectangular boxes representing the price range between two specific hours, with a horizontal line marking the midpoint of this range. This can be useful for visualizing price movements during a particular trading session or time period.

timec= time>=000000 and time<080000
if timec then
    hh=max(hh,high)
    ll=min(ll,low)
    if hh<>hh[1] then
        hhbar=barindex
    endif
    if ll<>ll[1] then
        llbar=barindex
    endif
endif
if not timec and timec[1] then
    drawrectangle(hhbar,hh,llbar,ll)
    drawsegment(hhbar,(hh+ll)/2,llbar,(hh+ll)/2)
    //rest
    hh=0
    ll=close*100
endif
return

This code snippet operates by defining a specific time condition and drawing rectangles based on the high and low prices during this period. Here’s a step-by-step breakdown:

• Time Condition: The variable timec checks if the current time is between 00:00:00 and 08:00:00. This sets the period during which the code will track high and low prices.
• Tracking Highs and Lows: Within the specified time, the code updates the highest (hh) and lowest (ll) prices encountered. It also records the bar index (time point) when these new highs or lows are observed using hhbar and llbar.
• Drawing the Rectangle: Once the time condition is no longer met (i.e., the time moves past 08:00:00), the code draws a rectangle from the first bar to the last bar where the new high and low were recorded, using these values as the top and bottom of the rectangle.
• Midline: A horizontal line is drawn at the midpoint between the high and low values across the same bars, visually splitting the rectangle into two equal parts.
• Resetting Values: After drawing the rectangle and midline, the high value is reset to 0, and the low value is set to 100 times the closing price, preparing the variables for the next session.

This snippet is particularly useful for analyzing price movements within specific time frames, providing a clear visual representation of high-low ranges and their midpoints.
