Smart Volatility Squeeze + Trend Filter

📌 Purpose
This indicator detects volatility squeeze conditions when Bollinger Bands contract inside Keltner Channels and signals potential breakout opportunities.
It also includes an optional EMA-based trend filter to align signals with the dominant market direction.

🧠 How It Works
1. Squeeze Condition
Bollinger Bands (BB): Length = 20, StdDev = 2.0 (default)

Keltner Channels (KC): EMA Length = 20, ATR Multiplier = 1.5 (default)

Squeeze ON: Occurs when BB Upper < KC Upper and BB Lower > KC Lower (low volatility zone).

2. Breakout Signals
Long Breakout: Price crosses above BB Upper after squeeze.

Short Breakout: Price crosses below BB Lower after squeeze.

3. Trend Filter (optional)
EMA(50) used to confirm breakout direction:

Long signals allowed only if price > EMA(50)

Short signals allowed only if price < EMA(50)

Toggle Use Trend Filter to enable/disable.

4. Visual & Alerts
Green circle at chart bottom indicates Squeeze ON.

Green/Red triangles mark breakouts.

Background gradually brightens during squeeze buildup.

Alerts available for long and short breakouts.

📈 How to Use
Look for Squeeze ON → then wait for breakout arrows.

Trade in breakout direction, preferably with trend filter ON.

Works best on higher timeframes (1h, 4h, D) and trending markets.

Markets: Crypto, Forex, Stocks — effective in volatile assets.
