Steam Market Item Price Tracker

Steam's market pages show you prices, but they don't tell you when to act. This extension does. Steam Market Item Price Tracker monitors buy and sell orders across the Steam Community Market and alerts you the moment prices, volumes, or spreads hit your targets. Real-time arbitrage calculations with accurate Steam fee breakdown — so you know your actual profit before making a trade. 🔔 6 ALARM TYPES — NEVER MISS A DEAL Buy price alerts — get notified when buy order prices drop below or rise above your thresholds Sell price alerts — track listing price movements with upper and lower bounds Buy volume alerts — detect rising demand before prices move Sell volume alerts — spot shrinking supply early Spread alerts — know when the buy/sell gap tightens and the market is most liquid Arbitrage alerts — set a minimum profit percentage after fees and get notified when a trade becomes profitable Each alarm type supports independent upper and lower thresholds. Breached thresholds are highlighted in red with one-click auto-adjust to current values. 💰 LIVE ARBITRAGE CALCULATOR Real-time profit calculation on every tracked item with accurate Steam fee breakdown — 5% Steam fee + 10% publisher fee applied correctly. See your potential profit amount and percentage before committing to a trade. No guessing, no manual math. 📊 LIVE MARKET DATA ON LISTING PAGES An expandable panel injected directly into Steam Market listing pages showing: Current buy and sell order prices updated in real time Live buy/sell volume from Steam's histogram data Full arbitrage breakdown with fee details Auto-expand option for tracked items — the panel opens automatically when you visit a tracked item's page Always-show arbitrage mode — see profit data even when the panel is collapsed 🎒 INVENTORY INTEGRATION A "Track on Market" button is injected into every marketable item in your Steam inventory.

The button updates automatically as you browse through your inventory. 🔍 SEARCH PAGE INTEGRATION Items you're already tracking show a "Tracking" badge directly in Steam Market search results. Hover for a tooltip showing your active alarm summary. Click to jump straight to the item's tracking panel. 🔔 SMART NOTIFICATIONS Desktop notifications for every alarm type — price, volume, spread, and arbitrage.
