Example: Crypto Strategy with Source Predictability

Scenario: Using News Sentiment as a BTC Trading Edge

You trade Bitcoin and want to know whether specific news sources' sentiment can give you an informational edge. This example walks through the complete process from initial analysis to daily monitoring routine.

Step 1: Run Source Predictability

Go to SentiLab and run Source Predictability for BTC with these parameters:

• Asset: Bitcoin (BTC)
• Time Range: 90 days (sufficient for statistical reliability)
• Min Quality: 0.7 (filter out low-quality sources)

Step 2: Analyze Results

The Source Predictability leaderboard returns the top 3 leading sources:

1. CoinDesk: +8h lag, r = 0.52 (strong, predictive)
2. The Block: +6h lag, r = 0.41 (moderate, predictive)
3. CoinTelegraph: +4h lag, r = 0.33 (moderate, predictive)

All three have positive lags — their sentiment leads BTC price. CoinDesk shows the strongest correlation with the longest lead time, making it the most valuable single source to monitor.

Step 3: Monitor Your Top Sources

Bookmark CoinDesk, The Block, and CoinTelegraph in the Sources directory. Check their individual source pages regularly for the latest analyzed articles from these key outlets.

Step 4: Establish a Daily Routine

Each morning, check Market Briefs and your top source pages. In 2–3 minutes, note the aggregate sentiment from your three leading sources:

• Are they collectively bullish, bearish, or neutral?
• Has the tone shifted since yesterday?
• Are any of them running significant stories that could move markets?

Step 5: Signal Detection

Your trigger condition: when 2 or more of your leading sources shift to strongly positive sentiment (sentiment score > +0.5) within a 4-hour window, this is a potential leading signal. Based on the lag analysis, expect corresponding bullish price action within 4–8 hours.

Note: a single source shifting is not enough. Requiring 2+ sources reduces false positives significantly.

Step 6: Validate with the Chart

Before acting on the trigger, check the sentiment vs price chart. Ask: has the price already moved? If BTC already rallied 3% in the last 4 hours while sentiment was rising, the signal may already be priced in. You are looking for sentiment shifts that precede price movement, not accompany it.

Step 7: Check Fear & Greed Context

Cross-reference with the Fear & Greed index:

• Leading sources bullish + F&G in neutral range (40–60): Good conditions for the signal — market is not at an extreme
• Leading sources bullish + F&G shows Extreme Greed (>76): Caution — the market may be overextended. Bullish sentiment in an overheated market can precede a correction rather than further gains
• Leading sources bearish + F&G shows Extreme Fear (<24): Potential contrarian opportunity — extreme fear can mark bottoms, but only if the bearish sentiment is event-driven rather than structural

Step 8: Risk Management

Even with converging signals from multiple leading sources:

• Never risk more than 2% of your portfolio on a single sentiment-based decision
• Set a stop-loss before entering — decide your exit before emotions enter the picture
• Remember: r = 0.52 (CoinDesk's correlation) means sentiment explains ~27% of price variance. The other 73% is driven by other factors
• Sentiment is one factor among many — always combine with technical analysis and broader market context

Disclaimer

This is an educational example, not financial advice. The source names and correlation values are illustrative. Past correlations do not guarantee future results. Always conduct your own analysis, use appropriate risk management, and never invest more than you can afford to lose. See Risk Management and Sentiment Analysis for a complete risk framework.

Why This Matters

This example demonstrates how Source Predictability transforms abstract correlation data into a concrete daily routine. Instead of monitoring hundreds of sources, you focus on the three that historically lead BTC price. Instead of guessing timing, you have a data-backed window (4–8 hours). The strategy is disciplined, documented, and realistic about its limitations. For a forex-focused approach, see Forex Strategy with Correlation Sweep.
