Inter-symmetric Forecast (ISF)

Concept:
The Inter-Symmetric Forecast (ISF) is a physics-inspired price projection tool that visualizes both trend-continuation and mean-reversion scenarios in one dynamic structure. It extends the classic ADAM Projection by introducing a regime-sensitive weighting based on the Market Reynolds Number (Reₘ), a dimensionless ratio of market momentum × liquidity to volatility-derived “viscosity.”
Mechanism:
ISF mirrors past price action around the current close (the continuation path) while also forward-pasting the same pattern unreflected (the anti-trend path). It then blends these paths bar-by-bar using time-reflected Reₘ values — meaning the liquidity-momentum regime of each past segment determines how much its future mirror leans toward continuation or reversion.
Interpretation:
High Reₘ → strong inertia/liquidity, favors trend continuation.
Low Reₘ → high friction/volatility, favors mean reversion.
The yellow blended forecast shows the regime-weighted midpoint between both outcomes.
Use:
ISF offers traders a visual probability corridor rather than a fixed prediction — illustrating how far a move might extend if momentum persists, or fade if conditions become viscous. It’s best used as a contextual forecasting overlay for discretionary or systematic analysis.
