Create Volume Spike Alert

WHAT IT DOES

This tool monitors 24-hour trading volume using the CoinGecko API and alerts you when volume spikes above a configurable multiple of the baseline volume. On first check, it stores the current 24-hour volume as the baseline. Subsequent checks compare the current volume against the baseline times your chosen multiplier. When the volume exceeds this threshold, the alert triggers. All alert configurations are stored in-memory — no data is persisted across page reloads.

HOW TO USE

Connect your MetaMask wallet using the Connect button. Give your alert a name, enter the token symbol (use CoinGecko IDs like "ethereum", "bitcoin", "polygon"), set the spike multiplier (e.g., 3x means alert when volume exceeds 3 times the baseline), and choose a check interval (5-300 seconds). Click "Create Alert" to start monitoring. Active alerts appear in the list. When a volume spike is detected, the alert status changes to "Triggered" and the event appears in the Volume Spikes log with the current volume and the multiple. Use "Remove" to delete an individual alert or "Clear All" to remove all alerts and history.

TECHNICAL MECHANISM

The tool does not read from the blockchain — it uses the CoinGecko public API's /coins/{id}/market_chart endpoint to fetch 24-hour trading volume. For each active alert, it creates a JavaScript interval that runs at the user-specified frequency. On the first successful check, the tool stores the current 24-hour volume as the baseline for that alert. On each subsequent interval tick, it fetches the current volume and compares it against the baseline multiplied by the user's spike multiplier. If the current volume exceeds the threshold, the alert triggers. The tool includes a volume history log that displays recent checks and spikes. All alert configurations and state are stored in-memory variables — no data is persisted to disk.

WHAT IT CANNOT SEE

This tool cannot persist alerts across page reloads because it runs in an opaque-origin sandboxed frame with no storage access. It cannot send push notifications or emails without external services. It cannot provide real-time volume data if the CoinGecko API is unavailable or rate-limited. It cannot detect volume spikes on tokens not listed on CoinGecko. It cannot detect spikes below the configured polling interval — a spike that occurs between checks will not be detected. It cannot detect intra-day volume volatility without more frequent polling, which may hit rate limits. It cannot detect volume spikes on non-EVM networks. It cannot provide trading signals or investment advice. It cannot detect volume spikes that occur between checks. It cannot distinguish between organic volume spikes and wash trading.

PLEASE NOTE

This tool works only with EVM-compatible wallets connected via the BGWallet bridge, but the volume data comes from CoinGecko and is not network-specific. The token symbol must match CoinGecko's ID exactly — common IDs include "ethereum", "bitcoin", "matic-network", "binancecoin", "solana", "avalanche-2", "arbitrum", "optimism". CoinGecko's public API has rate limits — frequent requests may be throttled. The baseline is set on the first successful check and does not update automatically unless you recreate the alert. Alerts are in-memory only and will be lost when the page is refreshed or closed. This tool is provided as a lightweight volume monitoring utility and should not be used as a financial trading signal or investment decision tool.
