Overview
Every set number of bars, it draws a primary purple horizontal line extending from the open price across a defined bar span. On every bar, it creates an independent copy of that line, restyles it with an orange dotted appearance, and anchors its end point to the current close price. It serves as a programmatic reference rather than a directional trading system.
- Periodic line drawing based on bar intervals
- Line object cloning demonstration
- Dynamic endpoint updates to closing prices
- Configurable bar length parameter
