Golden chart v1

## Golden Chart v1 – Trend Tracking & Signal Visualization Tool
**Version**: v1
**Pine Script**: version=5
**Visibility**: Invite-only

### Overview
Golden Chart v1 combines EMA-based trend bands (Golden Chart 2) with ATR-derived dynamic levels (Golden Chart 3) to help traders identify potential trend phases, visualize BUY/SELL signals, and color candles by trend direction.

### Key Features
- **Golden Chart 2 (EMA bands)**
- Calculates `emaHigh` & `emaLow` using `gc2_ema_period` (default 10)
- Determines SSL-style trend lines `sslUp` & `sslDown`
- **Golden Chart 3 (ATR levels)**
- Computes weighted ATR (`avgTR`) over `gc3_length` (default 13)
- Sets dynamic levels `hiLimit` & `loLimit` with `gc3_multiplier` (default 2.0)
- Plots `ret` line as the active trend level
- **Trade Signals**
- `BUY` label on bullish cross (`sslUp` → `sslDown` + close>open)
- `SELL` label on bearish cross (`sslDown` → `sslUp` + close<open)
- **Candle Coloring**
- Bars colored green/red based on trend position (`pos` = 1 or –1)

### User Inputs
- **Golden chart 2 EMA Period** (`gc2_ema_period`): EMA lookback for SSL bands
- **Golden chart 3 Length** (`gc3_length`): ATR/WMA length for dynamic levels
