Price Charting and Trends

Cards trend with 3-12 month lag from macro signals. Charts show momentum, volatility, and inflection points.

Chart features to look for

1. Trend (12-month moving average direction)
2. Volatility (standard deviation of monthly prices)
3. Inflection points (sudden change in slope)
4. Volume (sales count per month)
5. Support and resistance levels (psychological price floors/ceilings)

Chart sources

1. Card Ladder (most comprehensive, paid)
2. 130point historical data (free, less depth)
3. eBay sold listings exported manually
4. Goldin/PWCC auction archives
5. Custom Google Sheet from eBay API

Trend strategies

1. Up-trend with low volatility = hold, sell at next ceiling
2. Up-trend with high volatility = trim position, wait for stabilization
3. Down-trend = sell or hold long-term (no buying into weakness for set-completion only)
4. Flat with high volatility = buy/sell-the-range
5. Flat with low volatility = stable hold or set completion strategy
