Inkay 113/103 Price & Value

We require 37 complete days for the same printing and Near Mint condition. The latest seven days of sales are compared with the preceding 30 days, with at least 20 sales in that earlier period. Missing or interpolated observations are excluded.

Elevated activity means at least 1.5 times the earlier daily rate and at least 10 recent sales. Selling pressure takes priority when quotes fall at least 5% in seven days. Potential rebound requires a quote at least 10% below its earlier median and a latest three-day median no more than 2% below the previous four days. Upward momentum requires a rise of at least 5%. Fewer than 10 recent sales is labeled Thin trading.

These initial thresholds have not been validated for predictive accuracy. We record signals and later quote changes after seven and 30 days to evaluate them. Tracked volume covers tracked TCGPlayer sales, not the whole market.
