# How to Cap Daily Price Movement on TCGplayer

> Set a maximum percentage a TCGplayer price can move per sync in Hoard, with a hold or clamp mode and a split cap by price.

A price change cap limits how much a card's price can move in a single sync, so one spike, one bad market read, or one bot war can't blow out a listing before you notice. This is a Settings-page task — see [reacting to an active spike](/how-to/react-to-a-price-spike-tcgplayer) if you're dealing with one right now instead of setting this up ahead of time.

## Step 1: Open Settings > Pricing

Go to **Settings > Pricing** and find the change cap section.

## Step 2: Set your cap percentage

Enter a maximum percentage change for cards at or above your threshold price (default \$5.00). This is the cap most of your inventory will use.

## Step 3: Set a wider cap for low-value cards

Low-value cards need a wider cap than high-value ones — a $0.50 card moving to $0.75 is a 50% change but only 25 cents, while a $50 card moving 50% is a $25 swing. Set a separate, larger percentage for cards below your threshold so cheap cards aren't stuck refusing to move on ordinary market noise.

## Step 4: Set the threshold

The dollar threshold decides which of the two caps applies to a given card. Cards at or above it use your main cap; cards below it use the low-value cap.

## Step 5: Choose hold or clamp mode

* **Hold** rejects a change that exceeds the cap outright, keeping the card at its current price until a later sync (or a smaller move) lets it catch up.
* **Clamp** rate-limits the change instead — it applies the maximum allowed move rather than rejecting the update entirely, so the price still moves in the right direction, just capped.

## Step 6: Save and confirm

Run **Update Prices** or wait for your next sync, then check a capped card's pricing breakdown with **Test a card** on Settings > Rules to confirm the cap layer applied as expected.

## Choosing hold vs. clamp

Clamp mode is generally the safer default for ongoing use — the price still tracks the market direction, just more slowly. Hold mode is closer to a full stop, useful if you'd rather review a large move by hand than let even a capped version through automatically.
