Movement needs history, and history accumulates one scan at a time. Nothing here will be meaningful until you've been scanning for at least a couple of weeks — 4 snapshots minimum before a direction gets labelled at all. Tracking 32 cards so far.
Rising prices cut both ways: momentum can continue, but you're also paying more than the last buyer did. A card that already ran 40% is a worse entry than one that hasn't moved.
No rising cards identified yet. Keep scanning — movement needs several snapshots per card before it can be measured.
