Combined Crypto Signal

📈 Combined Crypto Signal — Trend + Momentum + Volatility Model

Combined Crypto Signal is a multi-factor trading model designed for crypto traders who want clean, high-probability Buy/Sell signals based on three proven pillars:

✅ Trend direction (EMA 200)
✅ Momentum confirmation (MACD + RSI)
✅ Volatility positioning (Bollinger Bands)

This script filters out noise and highlights only the strongest setups where trend, momentum, and volatility align together.

🔍 How It Works
1. Trend Filter — EMA 200

The script uses a long-term exponential moving average to determine market bias.

Price > EMA 200 → Bullish environment

Price < EMA 200 → Bearish environment

Signals only appear in the direction of the prevailing trend.

2. Momentum Confirmation — MACD + RSI

A signal requires momentum to agree with the trend:

Buy Momentum

MACD Line crosses above Signal Line

RSI is below overbought (default 70)

Sell Momentum

MACD Line crosses below Signal Line

RSI is above oversold (default 30)

This filters out weak crossover signals.

3. Volatility Check — Bollinger Bands

Price must be positioned on the favorable side of the middle Bollinger Band:

Buy: Price above BB Middle

Sell: Price below BB Middle

This ensures signals align with volatility expansion.

🎯 Final Buy / Sell Logic

A Buy Signal triggers when:

Trend = Bullish (Price > EMA 200)

Momentum = MACD Bullish Cross + RSI healthy

Volatility = Price above BB Middle

A Sell Signal triggers when:

Trend = Bearish (Price < EMA 200)

Momentum = MACD Bearish Cross + RSI healthy

Volatility = Price below BB Middle

Only when all three systems confirm, a triangle marker appears.
