How CardMoat Signals Work
CardMoat generates buy and sell signals by analyzing multiple factors for each card:
- Momentum Score — Short and medium-term price direction based on 7-day and 30-day changes
- Value Score — How undervalued or overvalued a card is relative to its historical price range
- Volatility Score — Price stability indicator; lower volatility means more predictable movements
- Mean Reversion — Detects cards that have deviated significantly from their average price and may snap back
- Breakout Detection — Identifies cards breaking out of established price ranges
