Fib Trend & Legs (BoaBias)█ OVERVIEW
Fib Trend & Legs (BoaBias) draws Fibonacci structure on two nested scales at once: a parent fib across the full market-structure trend cycle (trend-up ↔ trend-down), and child fibs on the BOS / CHoCH swing legs inside that trend. Optional golden / deep zones plus a CT-fade Edge panel (ALMA overheat · MTF EMA overheat · fib-anchored VWAP · golden proximity) with matching overlays. Structural context for discretionary work and alert workflows — not a black-box signal service.
█ WHY UNIQUE
Most Fib tools lock to a single hand-picked or last-swing range. This map keeps parent trend and child legs alive together : the parent tracks the whole structure trend cycle while child legs lock on each confirmed BOS/CHoCH segment (plus an optional forming leg). The Edge panel is a CT-fade confluence over that map: ALMA run overheat and MTF EMA above/below overheat (same lengths as BoaBias public EMA/ALMA), proximity to the parent golden zone, and a VWAP anchored at the parent fib start — so stretch + pullback context sit on one overlay instead of juggling three scripts.
█ HOW TO USE
First use: If the indicator appears in the wrong scale (squashed or fullscreen), right-click the indicator → Pin to scale → Pin to right scale.
Leave Show Parent Fib and Show Child Fibs on; tune Pivot Length so swings match your timeframe (higher length = fewer, larger structure events).
Watch Golden Zone / Deep Zone on the parent for pullback context; enable the same zones on child legs when you trade inside-leg retracements.
Use Pattern Edge (top-right) for parent-fib CT-fade confluence and Child Edge (bottom-left) for the active leg — high when pullback-side ALMA/EMA is stretched into golden near fib VWAP. Not a standalone entry trigger.
Alerts: Chart → Create alert → this indicator → choose a condition (Golden/Deep entry, Strong Edge, Cross Fib VWAP, Break 0%, Full Retrace, Trend Up/Down, BOS, Upsweep/Dnsweep). Prefer Once per bar close for cleaner automation.
█ HOW IT WORKS
Market structure: Pivot highs/lows feed a trend state. Trend flips (and BOS / CHoCH / optional liquidity sweeps) define when ranges update. Algorithm mode: Extreme Points or Adjusted Points.
Parent fib (Trend): Anchored to the full active trend cycle — from the cycle origin to the opposing extreme — with retracements, optional extensions, and zone fills between configurable ratios (defaults emphasize 61.8–78.6 golden and 78.6–88.6 deep).
Child fibs (Legs): Each leg = protective origin (CHoCH / last protect wick) → running extreme ( ms.main wick). Locked on BOS with those bars frozen. L1 = newest locked, L2 = previous, Lf = forming. Optional H/L anchor marks show the two wicks. Parent trend flip clears child history.
Edge layer (CT fade): Two panels — Pattern (parent fib) and Child (active leg). Each scores golden proximity (≤25) + ALMA pullback CT (≤25) + EMA pullback CT (≤25) + fib-start VWAP (≤25). ALMA/EMA CT use the chart timeframe only (panel shows e.g. ALMA 1D). For a bull fib, CT scores short / below-EMA stretch; bear fib scores the opposite. Optional plots: chart-TF ALMA SuperTrend, enabled EMAs, Pattern + Child fib VWAPs.
Sweep markers: Optional “x” markers when structure detects upsweep / dnsweep liquidity grabs (style group for color, size, max count).

█ LIMITATIONS
Pivot-based structure lags until pivots confirm; forming parent/child ranges can update until the next structure event.
Fib levels and zones are structural maps , not guaranteed support/resistance or trade signals.
Edge score is a confluence helper on the loaded history — descriptive, not predictive.
Heavy child history + many levels can hit drawing limits — lower Max Completed Child Legs or disable unused levels.
