NFT Collection Floor Tracker

WHAT IT DOES

NFT Collection Floor Tracker watches the current page for NFT collection floor price data, tracks floor price changes over time, displays historical trends and percentage changes, and triggers alerts when the floor price moves beyond user-defined thresholds. The tool helps you monitor collection value trends and react to price movements without constant manual checking.

WHERE IT RUNS

This tool works on any webpage that displays NFT listing prices and collection floor data, including NFT marketplaces, collection pages, and trading platforms. It automatically detects floor prices from page content using multiple detection strategies. The script runs on all websites as designated in its match patterns.

HOW TO USE

After installing the BotGentz extension, navigate to any NFT collection page. Click the NFT Collection Floor Tracker icon in your browser toolbar or use the keyboard shortcut (Alt+C). The panel will open. Click "Connect Wallet" to connect your real EVM wallet extension—this provides network context. Configure your alert threshold in ETH, choose the alert condition (Below Threshold, Above Threshold, or Percentage Change), set the percentage change threshold, and configure the check interval in seconds. Toggle desktop notifications, sound alerts, and price history display on or off. Click "Check Floor Now" for an immediate price check. Click "Start Monitoring" to begin automated tracking at your configured interval. The panel displays the current floor price, percentage change, a history log of recent price checks, and any triggered alerts. Use "Stop Monitoring" to pause tracking or "Reset Alert" to clear the triggered state.

TECHNICAL SECTION — FLOOR PRICE DETECTION AND TREND TRACKING

Unlike simple price display tools, this tool uses a floor price detection and trend tracking engine. It scans the page DOM using multiple strategies to identify floor prices—extracting prices from floor-specific labels, detecting price patterns from listing elements, and applying regex-based text extraction. Each price detection is timestamped and stored in local memory, building a history that captures price movements over time. The engine calculates percentage changes between consecutive checks, enabling clear visualization of trends. When the detected floor price crosses a user-defined threshold (below, above, or by a specified percentage), the tool triggers multi-channel alerts. The engine maintains state to prevent duplicate alerts on the same price movement, resetting only when the price moves away and crosses the threshold again. This approach provides reliable price tracking and alerts without requiring API access.

THE PANEL

The panel is draggable anywhere on the screen and remembers its position per site. It can snap to the left, right, top, or bottom edges, or float freely. Collapse it to a small status indicator when you need more page visibility, and expand it again with a single click. Resize it vertically or horizontally to show more of the history log. Press Escape to close the panel instantly. All settings (threshold, condition, change threshold, interval, notifications, sound, history) are saved globally and persist across sessions.

PLEASE NOTE

This tool requires the free BotGentz extension and a real EVM wallet extension already installed in your browser. EVM chains only—supports Ethereum Mainnet, Polygon, Arbitrum, and Optimism. Wallet connection is read-only; this tool never initiates transactions or signs messages. Cannot access real-time price data from off-platform sources, cannot detect floor price changes that occur between page refresh intervals, cannot read listing prices for NFTs that are not visible on the current page view, and cannot track historical data beyond what has been stored locally during the current session. Price history is lost when the browser tab is closed or if the script is reloaded without persistent storage between sessions. Always verify price information manually before making any trading decisions. Websites change their layouts frequently; scripts may need updates, and we work to keep them current but cannot guarantee uninterrupted operation.
