Price Trend Tracker for Path of Exile
Item prices in PoE shift constantly throughout a league. What costs 50c on day 3 might be 5 divine by week 4, or crash to nothing. This tool tracks price history across item categories so you can spot profitable windows before the rest of the market catches on.
How It Works
- Select a category tab (uniques, divination cards, currency, etc.) to load price history for every item in that category.
- Each item shows its current price, the price change over recent days, and a sparkline chart of the full league trend.
- Use the volume slider to filter out low-trade items — an item spiking 300% on 2 listings per day is noise, not signal.
- Sort by price change to find items that are rising or falling fastest right now.
- The search filter narrows results by name — useful when you want to track a specific unique or card.
Example: Spotting the Mid-League Unique Dip
On day 10 of a 90-day league, Mageblood (a meta belt) drops from 250 div to 180 div over 48 hours. Volume stays high (120+ trades/day) so this is a real market movement, not a data glitch.
Looking at historical leagues, Mageblood typically dips mid-league when a wave of players finish their main build and list their spare, then recovers by week 6 as new characters roll into endgame. Buying at 180 div and selling at 240 div five weeks later is a 33% return on a liquid asset.
The risk: league-wide nerfs, build meta shifts, or an unexpected patch can break the pattern. Never invest more than you can afford to lose, and check the sparkline for the current league — sometimes patterns break.
Tips
- Early league (days 1-5) prices are volatile and unreliable. Most items settle into stable ranges by week 2.
- Look for items that dip mid-league and recover later — this is the classic buy-low-sell-high pattern. Boss uniques often follow this curve as more players reach endgame.
- Divination cards that reward currently meta uniques tend to spike when popular build guides get published. Watch for content creator video drops.
- Currency items like Divine Orbs and Chaos Orbs have predictable league-start patterns. Divines usually climb for the first 2-3 weeks as demand outpaces supply.
- If an item shows a sudden spike with low volume, it might be price manipulation. Check the actual trade site listings before committing currency.
Common Mistakes
- Investing at league start. The first 3-5 days are pure volatility — prices on day 2 have no predictive value for week 3. Wait until volumes stabilise before building an investment thesis.
- Following a spike without checking volume. A 200% price jump on 5 listings per day is meaningless — one whale can set the price. Filter by minimum volume before trusting the signal.
- Holding too long. Prices typically crash in the final 2 weeks of a league as players cash out. Have an exit plan before you buy, not after.
- Ignoring market depth. The listed "price" is the median — if only 3 items are listed and the next one is 2× the price, your effective buy price is higher than the displayed number.
Frequently Asked Questions
- How far back does the price history go?
- Price data starts from league launch and updates roughly every 45 minutes via poe.ninja. You can see the full league trend from day 1 to the current day.
- What does the volume slider do?
- It filters out items with fewer daily listings than the threshold you set. Higher volume means the price data is more reliable — an item traded 500 times a day has a real market price, while one traded 3 times might not.
- Can I track Standard league prices?
- Yes — switch leagues in the settings gear icon. Standard prices move much slower than league prices, but the same tracking applies.
- Why did an item price suddenly jump to zero?
- If poe.ninja loses listing data for an item (no active sellers), the price drops to zero temporarily. This usually fixes itself within a few hours as new listings appear.
- Which categories are most predictable?
- Bulk currencies (divine orbs, chaos orbs) and meta uniques (Mageblood, Headhunter) follow the most predictable patterns because they have consistent demand. Niche uniques and divination cards are more volatile because demand depends on which builds are currently popular.
- Does this account for trade-site "bots" lowballing prices?
- No. poe.ninja prices are based on trade listings, which include bot-listed lowballs and stale listings. The median filters out some noise, but on thin markets the displayed price can be lower than what you can actually buy at. Always verify on the live trade site.
- What is the best strategy for first-time flippers?
- Start with high-volume items (divine orbs, common uniques) where price signals are reliable. Small gains on many trades beat big gains on a single illiquid bet. Build a cash reserve first, then graduate to larger flips as you learn the market rhythms.
- Can I save items to a watchlist?
- The portfolio sidebar lets you track items you are holding. There is no persistent per-item watchlist yet — use browser bookmarks or the portfolio to keep eyes on specific items.
