Overview
Points creates empty or sized integer and float arrays, checks that both arrays share the same length, and raises a runtime error when they diverge or when an index is out of range. Exported functions get, set, push, unshift, and insert values at a given index or at either end. It draws nothing and has no inputs, signals, or market-specific logic.
- Paired integer and float point arrays
- Size equality checks with runtime errors
- Index bounds validation
- Get and set at an index
- Push, unshift, and insert operations

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.
