Catch a TCGplayer price spike before it corrects

Search "TCGplayer price update frequency limit" and you get one bare help article, no interpretation, nothing about why the frequency matters. That's odd, because the frequency question has an upside case that gets almost no attention: a spike you don't notice in time is money you never collected, and there's no floor or ceiling that helps you here. Floors and ceilings protect you from pricing too low or following a bad reference up too far. Neither one helps you catch a card that's moving fast in your favor.

What a spike actually looks like

A card that's sitting quietly at $8 can triple on a ban announcement, a tournament finish, or a reprint rumor, and it can largely correct back toward its prior price within days once the news settles and supply catches up. If your prices were set before the spike and nothing checks again until the spike has already passed, you sold at $8 through the entire window where the card was worth $24. The listing didn't do anything wrong. It just wasn't looked at often enough.

This isn't a rare edge case. We tracked a fixed basket of actively-traded products across seven major games for eleven consecutive weeks, checking what share moved more than 10% week over week. In a typical week, that's roughly 5-7.5% of tracked cards across Magic, Pokémon, One Piece, Digimon, and Yu-Gi-Oh! — meaning most weeks, dozens of cards in a mid-size store's inventory are moving enough to matter, whether or not anything checks them. And "typical" understates it around a real catalyst: in the three weeks before Dragon Ball Super's BT31 and ST01 set releases (August 2026), the same measurement jumped to 19-25% of tracked cards moving more than 10% in a single week — up from a 1-4% baseline for that game in calmer weeks. That's the shape of a spike: quiet, then suddenly not, then quiet again once the news is priced in.

Schedule-only tools aren't built to notice this

MassPrice runs on a schedule you set, and it does that reliably. But it has no documented concept of detecting a spike as distinct from a normal price move — it was built to hold a price at a target relative to the market, not to notice when the market itself has jumped. A rule set to run once a week will eventually update the price, but by then the spike may have already come and mostly gone. The tool didn't fail. It just wasn't asked to solve this problem.

Cadence is the actual lever, not the rule

This is the part that's easy to miss: catching a spike isn't a matter of writing a smarter rule. A perfect rule that only runs weekly still only sees the market once a week. The lever that determines whether you catch a move at all is how often something checks, not how sophisticated the check is when it runs. We go through how to reason about your own cadence needs in how often you should reprice your TCGplayer cards.

Why we sell repricing by sync frequency, not by feature list

This is the reason Hoard's plans are priced on how often your store syncs rather than a flat set of features gated behind a tier. Gold syncs weekly. Platinum syncs daily. Diamond syncs every four hours, specifically because a four-hour cycle catches moves that a weekly cycle would only notice days later, after the correction has already happened. The rule logic doesn't change between tiers. What changes is how often it gets a chance to see the market. See the full breakdown on Gold, Platinum, Diamond, and Vault plans, and how the sync itself works in Hoard's repricing agent.

What to do once you catch one

Catching a spike doesn't mean chasing it blindly upward. It means your listing reflects the current market while the market is elevated, instead of reflecting last week's market for the entire window that mattered. Pair a fast enough cadence with the floor and ceiling discipline from setting price floors and ceilings and you get a rule that moves with the market in both directions, not just down.
