RSI or MFI
The momentum engine has two interchangeable hearts.
The stack's momentum read can run on RSI(14) or MFI(14) — the volume-weighted variant — and the choice is a liquidity decision, not a preference:
- RSI is the baseline: purely price-based, reliable on every pair, immune to tick-volume quality.
- MFI adds participation: on majors, and on crosses during London/NY hours, tick volume tracks real liquidity well enough that MFI confirms whether pushes have flow behind them.
- On thin crosses and off-hours, tick volume misleads — RSI is the dependable read there.
- Thresholds are strict either way: ≥ 60 for bullish bias, ≤ 40 for bearish — midline drift does not qualify as strength.
