Overview
The left edge is the previous bar index and the top is the previous bar's low. The right edge is the current bar index and the bottom is the current bar's high. It plots directly on the price chart with overlay enabled. There are no user inputs, no trading signals, and no entry or exit rules. The boxes accumulate as new bars form and the script does not calculate indicators or alerts.
