Weather Score — subscores (0–10) + Total (30/40)

Weather Score — Readiness + Signals (purple/pink) 🌈

What it is:
A compact market “weather” gauge that scores Trend, Momentum, Volatility, and Flow from 0–10 each, then combines them into a total readiness score (/30 or /40 depending on which modules you enable). It paints a draggable badge, a mini table, optional legend, and fires GO/NO-GO + Volatility OUT/IN signals with alerts.

How the score works

Trend (EMA50/200 + slopes): adds points when price is above EMAs and their slopes are rising.

Momentum (RSI • Stoch • MACD hist): blended weighting for balanced momentum read.

Volatility (BB width percentile): quiet regimes score higher (breakouts favored); bonus when leaving quiet.

Flow (VWAP/MA anchor): where price sits within ±2×ATR of the anchor. Intraday uses VWAP; higher TFs use SMA(mvLen).

Total is normalized to 0–100% and mapped to a weather state: 🌧 Rainy → 🌫 Storm Clearing → ⛅ Clearing → ☀️ Sunny → 🌈 Blue Sky.

Robustness: Flow returns a neutral 50 until ATR/anchor are ready (so you don’t see na on fresh charts).

Signals (on chart + alertable)

BUY (GO): readiness crosses up your goPct threshold.

SELL / Exit (NO-GO): readiness crosses down your nogoPct threshold.

Go OUT (Expansion): BB-percentile crosses up the quiet threshold.

Go INSIDE (Contraction): BB-percentile crosses down the quiet threshold.
Optional: paints bars when GO/NO-GO is active, and drops tiny labels at flips.

Visuals & UI

Badge: draggable or auto-locked to last bar, with ATR-based Y-offset and X-offset (bars). Color follows score via purple/pink gradient.

Mini Table: module subscores, quick notes, and totals.

Legend (top-center): quick read of weather bands & emojis.

Alerts

Prebuilt alert conditions for: BUY (GO), SELL (NO-GO), Go OUT, Go INSIDE, plus simple GO/NO-GO rules.

Messages in alertconditions are constant (TradingView requirement); the script also emits runtime alert() pings on bar close with richer text if the indicator is running.
