Regime Game Probability Forest
This overlay indicator scores a bull, bear, or neutral game state from an auditable decision-forest probability rather than a fitted machine-learning model or live API.

Source Code
The code stays on GitHub. The author has not published this script under an open licence, so ForexR does not show its code. Copy script reads the file straight from GitHub into your clipboard, so you can still try it on your own chart. Ask the author before reusing the code anywhere else.
Overview
Regime Game Probability Forest compares the smoothed probability with bull and bear thresholds, then shifts it when a strong intervention-flow regime is active. Regime data come from manual flow inputs or a four-ETF basket proxy. It colors candles, highlights the regime, labels state changes, and shows a dashboard. It does not place trades.
- Bull and bear probability thresholds
- EMA-smoothed decision-forest score
- Walk-forward probability calibration
- Manual flow or ETF basket regime
- Candle colors, labels, and dashboard

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.
