Based on the Weekly Relative Strength Index (14-period). Measures whether BTC is oversold or overbought on the weekly timeframe. A low RSI (<35) signals oversold conditions and produces a high score, indicating a potential buying opportunity. A high RSI (>70) signals overbought conditions and produces a low score, warning of possible correction.

Aggregates the last 50 headlines from CoinDesk, CoinTelegraph, and Bitcoin Magazine RSS feeds. Each headline is scored using VADER sentiment analysis (with a crypto-specific lexicon) on a scale of -1 (bearish) to +1 (bullish). The average compound score is mapped to 0-100. Extreme positive sentiment (>75) can be a contrarian sell signal (euphoria), while deeply negative sentiment may indicate capitulation.

Measures the social media tone around Bitcoin using CryptoPanic vote data (if API key is configured) or VADER analysis of aggregated news titles as a proxy. When the CryptoPanic API is active, it uses the bullish/bearish vote ratio from the community. When social score spikes above 80 while RSI is above 65, a Macro Top Warning is triggered, indicating potential euphoria at a price peak.

The weighted average of all three signals: Technical 40% + News 35% + Social 25%. Technical analysis is weighted highest because weekly RSI is a proven macro indicator. The composite produces a final signal used for email alerts.
