Market indicators
Signals are grouped by collector decision.
01
Momentum
Track recent movement direction so cards with changing attention are easier to review.
02
Liquidity
Separate cards that move often from cards that may need patience, better photos, or a different sale lane.
03
Volatility
Flag unstable movement so buy, sell, hold, or grade decisions have better context.
04
Supply vs demand
Compare listing pressure and collector interest before treating a price change as meaningful.
05
Raw vs graded spread
Review whether grading consideration makes sense after condition, fees, timing, and risk are weighed.
Cards needing price review
Inventory rows that crossed the movement threshold and need a fresh look.
Cards with changed market value
Snapshot comparisons that make value movement easier to spot without claiming certainty.
Cards worth grading review
Cards where condition, fees, raw value, and graded spread may justify a closer grading-prep check.
