OPEN-SOURCE SCRIPT
Over Extension Lines

Takes yesterday's range and projects it onto today to show where price is overcooked. It grabs the prior day's high, low, and range, throws up extension levels above and below, and draws the 9:30 to 9:45 opening range on top. When price tags an extension it's stretched relative to what yesterday actually did, which is where moves tend to stall or turn. Use the extensions as reversion targets and exhaustion spots, and the opening range as your first structure of the day. The prior-day numbers come off the last completed daily bar, so that reference doesn't repaint.
