MFI Advanced — port CCI Advanced view onto a Money Flow Index core

[casoon]

Port the "trend context + stall + conviction + divergence + long/short coloring" view from CCI Advanced (indicators/momentum/cci_advanced/cci_advanced.pine, v1.2.0) onto an MFI core. New indicator, not a mode of CCI Advanced.

Do after #41 (Stoch RSI) — reuse the exact framework structure established there.

Why separate

Same reasoning as #41 (static Pine input defaults, bounded vs zero-centered). Extra reason for MFI: it requires volume, so it must stay isolated — folding it into the CCI/StochRSI indicators would create a dead mode on no-volume instruments (forex, some indices).

Keep identical framework structure

Same section order as CCI Advanced: Core → Mid/Levels → Stall → Trend Context → Conviction → Divergence → Plots → Alerts.

Portable as-is

• Trend context line = slow MFI (longer length), faint behind the fast line, long/short colored
• Stall/absorption = oscillator-slope vs ATR-normalized price-slope (threshold rescaled to 0–100, ~15)
• Cross conviction = MFI/signal cross contradicted by flat price or counter-trend → weak/faded triangle
• Trend↔CCI divergence wedge = fill between fast and trend-context line that lights up only when they move opposite (supported dip vs unsupported bounce); n-bar slope + min-slope noise guard. Rescale min-slope to the 0–100 range (~10 instead of 25)
• Long/Short coloring = green/red on trend context line + histogram + divergence wedge, teal/pink reserved for level

Adaptations vs CCI

• MFI is single-line → signal = smoothed MFI (same kernel) as the cross partner, like CCI's signal
• Bounded 0–100: drop the three scale modes
• Midline 50 (not 0); "zero cross" → 50-cross
• OB/OS defaults 80 / 20
• Gradient keyed on 20/80
• Shadow fill to 50
• Long = above 50, Short = below 50
• Volume guard: handle symbols without volume gracefully (e.g. note in README; no crash)

Deliverables

• indicators/money_flow/mfi_advanced/mfi_advanced.pine (category: money_flow)
• README.md, CHANGELOG.md (v1.0)
• Header per CLAUDE.md ([WavesUnchained], ✓ features, Build date)
• Root README.md + CATALOG.md entries
• Validate in TradingView for CE errors
