Momentum Trend Signals: Buy/Cautious/Add/Sell with EMA Filter

Momentum Trend Signals is a trend-following and momentum-based indicator designed to assist traders in identifying optimal entry and exit points using a combination of price action patterns, EMA filters, and RSI strength.

📌 Core Logic:
This script generates Buy, Cautious, Add, and Sell signals based on:

Candle Structure: Checks for strong higher highs/lows (buy) or lower highs/lows (sell).

Momentum Confirmation: Uses RSI > 50 for bullish strength.

Trend Filter: Employs a combination of EMA21 and EMA50 to confirm trend direction.

Long-term Trend: Incorporates a 30-week WMA (approximated as a 150-day WMA) to align with broader trends.

✅ Signal Definitions:
Buy (B): Triggered when price shows upward momentum with RSI and EMA filters confirming bullish strength above 30-week WMA.

Cautious (⚠️): Warns of potential short-term weakness in an ongoing uptrend.

Add (A): Suggests re-entry or position addition after a bounce from EMA21, following a Cautious signal (not after a Sell).

Sell (S): Activated when bearish candle structure aligns with price closing below EMA21, indicating a breakdown in momentum.

📊 How to Use:
Use Buy signals to initiate long positions when all trend conditions align.

Monitor Cautious alerts to manage risk or tighten stops.

Consider Add signals to scale into winning positions.

Use Sell signals for potential exits or short opportunities.
