Metric	What it Measures	Why it's Useful
Card Profile	A side-by-side snapshot of each card's raw sale history and key stats, shown directly without any derived scoring.	Lets you review the underlying data itself before any metric interprets it — useful for spot-checking individual sales or understanding why a metric came out the way it did.
Price Appreciation	Total percentage gain over a period.	The simplest measure of return and growth.
Maximum Drawdown	Largest percentage decline from a previous peak.	Measures downside risk. Smaller drawdowns mean the asset has historically held up better during market declines.
Sales Velocity	How quickly something sells.	High sales velocity signals strong demand. For collectibles, it often precedes price appreciation if supply is limited.
Capital Flow	Whether money is entering or leaving an asset.	Rising prices with increasing capital inflow are generally healthier than price increases on low participation.
ATH Proximity	How close the current price is to its all-time high.	Strong assets often trade near their highs. A card at 95% of its ATH is generally stronger than one at 50%, even if both have risen recently.
Time Above Moving Average	Percentage of time the price stays above a moving average.	A high percentage suggests a persistent uptrend. Assets that spend most of their time above key averages tend to outperform over long periods.
Trend Strength	How strongly price is moving in one direction.	Distinguishes a weak drift from a powerful trend. Higher values usually indicate stronger momentum.
Recovery Efficiency	How quickly an asset rebounds after declines.	Fast recoveries indicate resilient buying pressure and investor confidence.
Breakout Frequency	How often an asset makes new highs or breaks above resistance.	Frequent breakouts often indicate sustained demand and strong momentum rather than random price movement.
Composite Alpha Score	A single, weighted score combining multiple metrics above into one number, with each metric's weight set by you.	Lets you prioritize the specific factors that matter most to your own investing or collecting goals, rather than relying on a one-size-fits-all formula.

Card Profile

A side-by-side snapshot of each card's raw sale history and key stats, shown directly without any derived scoring.

Lets you review the underlying data itself before any metric interprets it — useful for spot-checking individual sales or understanding why a metric came out the way it did.

Price Appreciation

Total percentage gain over a period.

The simplest measure of return and growth.

Maximum Drawdown

Largest percentage decline from a previous peak.

Time Above Moving Average

Percentage of time the price stays above a moving average.

A high percentage suggests a persistent uptrend. Assets that spend most of their time above key averages tend to outperform over long periods.

Trend Strength
