Smart Deviation Trend Bands PRO + MTF Filter

395
📌 Purpose
This indicator combines multi-level Deviation Bands (±1, ±2, ±3 standard deviations from SMA) with a Higher Timeframe (HTF) Trend Filter.
It helps traders identify potential bounce and breakout setups aligned with the dominant market trend.

🧠 How It Works
1. Deviation Bands
SMA(Length) is calculated as the centerline.

Standard deviations (±1, ±2, ±3) define multiple dynamic support and resistance zones.

Outer bands (±3) often mark overextended zones; inner bands (±1, ±2) show active trading areas.

2. HTF Trend Filter
A higher timeframe SMA (HTF SMA) acts as a trend confirmation tool.

Default filter timeframe: 1 Day.

Trend Up: Price > HTF SMA

Trend Down: Price < HTF SMA

3. Entry Signals
Long Signal: Price crosses above lower deviation band (+1) when HTF trend is UP.

Short Signal: Price crosses below upper deviation band (−1) when HTF trend is DOWN.

4. Visuals & Alerts
Bands plotted in red (upper) and green (lower).

Centerline = SMA in blue.

HTF SMA in orange.

Circles on chart mark entry points; alerts trigger automatically.

📈 How to Use
In trending markets: Trade with the HTF direction, using band touches for entries.

In mean-reversion setups: Outer bands can be used to spot potential overbought/oversold zones.

Combine with volume or price action for confirmation.

Recommended Timeframes: 1h, 4h, D.
Markets: Forex, Crypto, Stocks.
