Overview
My Script creates a new visual label at the bar index and high price of each bar directly on the main price chart. The script does not calculate technical indicators, generate trading signals, or include customizable input settings. A notable limit is that it caps the total visible label drawings at one hundred instances using the study declaration parameter, leaving older historical bars without labels.
- Label drawing demonstration
- Direct price chart overlay
- Maximum label count limit

Third-party code. ForexR did not write, test or endorse this script, and the summary above was generated automatically from its code and README. Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.
