DualWave Trend Signal [Auto1491]

📘 English Description
DualWave Trend Signal [Auto1491] is a trend-following indicator based on dual-layer dynamic price zones.

It computes two independent high/low ranges:

Outer Range (Z): a longer-term view of market extremes

Inner Range (Z1): a shorter-term perspective to refine entry/exit signals

The indicator dynamically adjusts two trend lines, then determines whether the price action confirms a bullish, bearish, or neutral trend. BUY and SELL signals are visualized on the chart, and bar colors reflect trend direction for quick reference.

✅ Features:
Dual-band price range logic for trend detection

Dynamic trend line adjustment based on historical highs/lows

Visual buy/sell signals at key inflection points

Color-coded bars: green (bullish), red (bearish), unchanged (neutral)

Real-time label showing the current market condition

🎯 How to Use:
Bullish when close > outer trend AND inner trend

Bearish when close < outer trend AND inner trend

Neutral otherwise

Entry signals appear on the first bar confirming a trend change

Suitable for intraday traders and scalpers in high-volatility markets like gold, forex, and indices.

📙 中文說明
DualWave Trend Signal [Auto1491] 是一款基於雙重區間邏輯的趨勢判斷指標，透過動態高低區間辨識市場多空狀態。

本指標計算兩組不同比例的區間：

外層區間（Z）：長期波動參考，捕捉趨勢主幹

內層區間（Z1）：短期變化參考，用於精準進出點

當價格突破這兩條趨勢線，即顯示「多頭」或「空頭」訊號，並將K棒上色，方便用戶快速判斷目前市場狀態。

✅ 特點：
採用雙趨勢帶邏輯（內層＋外層）

根據高低價動態調整趨勢線

明確的買賣訊號圖示

自動變色K棒：綠（多）、紅（空）、不變（盤整）

圖表右上實時顯示「目前趨勢狀態」

🎯 使用方式：
多頭：當收盤價 > 內層與外層趨勢線

空頭：當收盤價 < 內層與外層趨勢線

盤整：未同時突破上述趨勢線

當趨勢轉變時會出現首次進場訊號

適用於黃金、外匯、指數等高波動性市場的日內交易者。
