Overview

DrawLevels visualizes hardcoded horizontal price levels, support and resistance zones, and value area references such as prior day, weekly, and monthly high, low, and point of control markers. The script provides no trading signals. Main user settings allow customizing the display colors for resistance, support, and value area lines. A key limitation is that all price levels are hardcoded rather than dynamically calculated, making them specific to a fixed price range.

predefined support and resistance lines
support and resistance range boxes
value area levels and labels
