Overview
Gary - Oscillator multiplies volume by the difference between close and open divided by their sum, scales that value by one hundred, and smooths it with a fourteen-period VWMA. Columns are teal above zero and red below zero. Candle body and wick buy and sell volume terms are calculated but not plotted. There are no user inputs, and the lookback stays fixed at fourteen bars.
- Fourteen-period volume-weighted moving average
- Close-open volume ratio scaled by 100
- Teal and red column histogram
- Calculated but unplotted buy and sell volume
- Fixed lookback with no inputs

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.
