S/R Zones MTF v2

Multi-timeframe support/resistance zones built from ATR-reversal structure swings. For each configured timeframe the script tracks swing highs/lows where the reversal exceeded an ATR-based threshold; these become zone boundaries that are scored, merged across timeframes, and tracked through tests, sweeps, breaks (with role reversal) and retests.

Features

Up to two configurable higher timeframes plus the chart timeframe (all lookahead_off)
ATR-based reversal swing engine — zone boundaries from volatility-relative reversals, not fixed pivot counts
Zone merging: overlapping same-side zones consolidated, with a too-close filter against duplicates
Zone scoring: touch, rejection wick, close location, impulse, age penalty — weights configurable
Event detection per zone: Test (T), Sweep (SW), Break (B↑/B↓ with role reversal), Retest (R) with min-bars delay and label cooldown
Break rules: wick or close invalidation, optional volume confirmation, ATR break buffer
Optional faded snapshot of invalidated zones
Score filter: zones below the minimum score are faded out
Alerts: zone break up/down, retest, sweep

Scoring

Each zone starts with a timeframe boost (Chart 0.5, HTF1 1.0, HTF2 2.0) and accumulates:

+ wTouch per test, plus quality bonuses for close location, rejection wick and impulse
+ 0.7 × wTouch per sweep
+ 1.5 × wImpulse + 0.5 × wCloseLoc per break
+ 1.2 × wTouch per confirmed retest
− wAge per bar (age decay)

When the zone limit is reached, the lowest-scoring zone is dropped (or the oldest, when the filter is off).
