Cryptocurrency Volume/MCAP Screener - Automated Trading Alerts to Discord

This n8n workflow automates the process of fetching cryptocurrency data, applying custom screening logic, and sending alerts to Discord. It's designed for traders and enthusiasts who want to stay informed about significant market movements based on volume and market capitalization.

What it does

This workflow performs the following steps:

1. Triggers on a schedule: The workflow runs automatically at predefined intervals.
2. Fetches cryptocurrency data: It makes an HTTP request to an external API to retrieve current cryptocurrency market data.
3. Applies conditional logic: It uses an "If" node to evaluate conditions on the fetched data, likely filtering for cryptocurrencies that meet specific criteria (e.g., high volume, significant market cap changes).
4. Processes filtered data: The data that passes the "If" condition is then processed further.
5. Handles non-matching data: Data that does not meet the "If" condition is also processed, potentially for logging or alternative notifications.
6. Merges data streams: It combines the results from both the "true" and "false" branches of the "If" node.
7. Executes custom code: A "Code" node is present, indicating custom JavaScript logic is applied to the data. This could be for further data manipulation, formatting, or more complex calculations before sending alerts.
8. Sends alerts (implied): Although not explicitly shown in the provided JSON (which only contains core nodes), the typical next step for such a workflow, especially given the directory name, would be to send the processed alerts to a platform like Discord using a dedicated node (e.g., a Discord node).

Prerequisites/Requirements

• n8n Instance: A running n8n instance to host and execute the workflow.
• Cryptocurrency API: Access to a cryptocurrency market data API (e.g., CoinGecko, CoinMarketCap, or similar) from which the "HTTP Request" node will fetch data. You will need the API endpoint and any necessary authentication headers/parameters.
• Discord Account/Webhook (implied): A Discord server and a webhook URL configured to receive messages, if the goal is to send alerts to Discord. This would require an additional Discord node in the workflow.

Setup/Usage

1. Import the workflow: Download the provided JSON and import it into your n8n instance.
2. Configure the Schedule Trigger: Adjust the "Schedule Trigger" node to your desired frequency for checking cryptocurrency data (e.g., every 5 minutes, hourly).
3. Configure the HTTP Request node:
   • Set the URL to your chosen cryptocurrency API endpoint.
   • Add any required Headers (e.g., API keys) or Query Parameters for authentication or data filtering.
   • Ensure the Method is set correctly (likely GET).
4. Configure the If node:
   • Define the conditions for screening cryptocurrencies based on your trading strategy (e.g., volume > 100000000 && marketCapChange24h > 0.1). Use expressions to reference data from the previous "HTTP Request" node.
5. Configure the Code node:
   • Review and modify the JavaScript code within this node to perform any specific data transformations, calculations, or message formatting you need for your alerts.
6. Add Discord (or other) notification node (if not already present):
   • Connect a "Discord" node (or your preferred notification service like Slack, Telegram, Email) after the "Code" node.
   • Configure the notification node with your webhook URL or API credentials.
   • Map the output from the "Code" node to the message content of your notification node to send formatted alerts.
7. Activate the workflow: Once configured, activate the workflow in n8n.
