Signal uses price history only. Grading ROI, graded-market trend, and population scarcity activate when graded data is available.
Recent price movement
Price recently fell 8.1% (30d).
In our price history, declines like this have more often been followed by a recovery than by a further fall. Thinly traded cards can produce that pattern for reasons unrelated to demand, so treat it as an observation, not a forecast.
