Question 1

What is MTG sealed box arbitrage?

Accepted Answer

MTG sealed box arbitrage means buying sealed booster boxes at a price lower than what dealers will pay on their buylist, or lower than expected card value, then selling into those buylists for a profit. Dealer Signals tracks the spread between TCGPlayer market price and every major dealer buylist daily to surface these opportunities.

Question 2

How do I find underpriced MTG boxes?

Accepted Answer

Use Dealer Signals to monitor the gap between TCGPlayer market price and dealer buylist offers. When that spread compresses (the buylist rises toward retail), it signals that dealers anticipate higher demand and retail is likely to follow. Filtering by 'compressing' trend shows the boxes most likely to move soon.

Question 3

What does spread compression mean in MTG finance?

Accepted Answer

Spread compression means the gap between dealer buylist price and retail market price is getting smaller. Dealers raise buylists before retail reprices because they have superior sales velocity data. A compressing spread on a sealed box is one of the earliest signals that retail prices are about to rise.

Question 4

Which MTG dealers are tracked on Dealer Signals?

Accepted Answer

Dealer Signals tracks buylist prices from Card Kingdom, Star City Games, Channel Fireball, and other major US dealers. It also tracks Manapool EU prices for transatlantic spread analysis.
