Overview
The script initializes a persistent floating-point array and dynamically inserts new elements on each bar execution, causing the array size to grow continuously. It plots the resulting array length as a line in a separate indicator pane. This script serves primarily as a code demonstration or test for dynamic array expansion and does not calculate traditional technical analysis indicators or market signals.
- Dynamic array insertion logic
- Persistent array state tracking
- Array length visualization plot

Risk Notes
No repainting, lookahead or stacked entries were found in its code or README. That says nothing about how well it works: test it first.
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. Check it in the Strategy Tester and on a demo account before you rely on it.
