Quick Answer
The C3 Market page at /market shows seven-day price trends for TCG cards in the Australian market, updated from live eBay AU data. This guide explains how to read the data, what the trends mean, and how to use them to time your buying and selling decisions.
What the Market Page Shows
The Market page displays cards with the largest price movement over the past seven days in the Australian market. Both upward and downward movements are tracked. Upward movers have increased in AUD value, indicating rising demand. Downward movers have decreased, indicating falling demand or increased supply. The magnitude of movement matters: a card up 50 percent in seven days signals a significant event. A card up 5 percent is normal market noise.
What Causes Price Movement
The most common causes of upward price movement in the Australian TCG market are: a card performing well in a major tournament, a prominent content creator featuring the card, a supply reduction (set going out of print), or a ban list change removing a competing card. The most common causes of downward movement are: a card being hit by a ban or limit, a new set releasing a better version of the same effect, or increased supply from a reprint.
Using the Market Page Before Buying
Before buying any card worth over AU$20, check whether it appears on the Market page. If the card is trending up significantly, you may be buying at or near a peak. If it is trending down, you may find a better entry price by waiting one to two weeks. The Market page does not predict the future, but it shows momentum, and momentum in card markets tends to continue for short periods before correcting.
Using the Market Page Before Selling
Before listing a card for sale, check if it has recently spiked on the Market page. Cards that spiked in the past 48 to 72 hours are still in the high-demand window. List immediately and price at the spike price rather than the pre-spike price. Cards that spiked four to seven days ago may already be correcting. Check the current price versus the seven-day high to see where in the spike cycle you are.
The Seven-Day Limitation
The Market page shows seven-day data, which is useful for short-term timing but not for long-term trend analysis. A card can spike for a week due to tournament hype and then fall back to its original price. Do not interpret a seven-day spike as evidence of permanent value increase. For longer-term price trends, cross-reference with the card's price history on eBay AU sold listings going back 30 to 90 days.
Setting a Monitoring Routine
Check the Market page weekly before your regular buying or selling activity. A five-minute review of current movers keeps you informed without requiring constant monitoring. Combine the Market page with the Collection Tracker at /tracker to identify when cards in your own collection are showing significant movement that warrants a selling decision.
How This Tool Fits the Full C3 Toolkit
The C3 tools are designed to work together as a complete decision-support system for Australian TCG collectors and players.
The EV Calculator at /tools answers the sealed product question: is this box worth opening at my purchase price? It uses current AU card prices to give a verdict before you commit to opening.
The Card Compare tool at /compare answers the singles question: how do these specific cards compare in current AUD value? It shows up to four cards side by side with price trends.
The Market page at /market answers the timing question: is this card's price moving up or down right now? It shows seven-day price trends for the Australian market.
The Collection Tracker at /tracker answers the portfolio question: what is my collection worth, and am I ahead or behind on my investment? It tracks purchase prices and current values across eight games.
Using all four tools together gives you visibility into sealed product value, individual card value, price timing, and overall collection performance simultaneously. No single tool gives the complete picture. The combination does.
The C3 Take
The Market page at /market gives Australian TCG players an advantage that most buyers and sellers do not have: visibility into what is moving right now at current AU prices. Used consistently, it catches opportunities to sell at peaks and buy at troughs that are invisible to players who only check prices when they are about to transact.
