Tesla Stock Technical Indicators API Data Retrieval - n8n Workflow

Quantitative traders or developers building algorithmic trading systems.
Users seeking reliable, cleaned stock market data streams for AI or analytical models.
n8n power users who need highly customized API integration and data standardization.
Developers needing high-performance financial data provisioning tools.

This expert n8n workflow serves as a high-performance data abstraction layer for retrieving detailed technical indicators for Tesla stock (TSLA) from Alpha Vantage. It solves the complexity of managing multiple API calls and standardizing inconsistent output formats. By exposing three distinct webhook endpoints, this powerful n8n workflow allows calling applications to request 15-minute, 1-hour, or 1-day data instantly. The workflow handles six key indicators—MACD, RSI, BBANDS, SMA, EMA, and ADX—ensuring that the latest 20 data points are cleaned, formatted using the custom JavaScript within the n8n node Code functions, merged, and returned as a single, easily digestible JSON object. These n8n templates are crucial for reliable quantitative analysis and automated trading strategies built on the n8n platform.

1. Trigger Reception: The process begins when an external application calls one of the three Webhook nodes (the core n8n trigger points): /15minData, /1hourData, or /1dayData. This allows other n8n templates or external systems to easily request specific data batches.


2. Parallel API Fetch: The incoming n8n trigger immediately activates six parallel HTTP Request nodes. Each n8n node contacts the Alpha Vantage API for one of the six specified technical indicators (MACD, RSI, BBANDS, SMA, EMA, ADX) at the requested timeframe (e.g., 15min).


3. Data Cleaning & Standardization: The raw JSON output from each indicator API call is routed to a corresponding Code n8n node. This custom n8n node executes JavaScript to parse the data, extract the latest 20 data points, and reformat the results into a consistent JSON schema ({ indicator, timeframe, data }).


4. Result Merging: The six standardized outputs flow into a Merge n8n node. This node combines all six independent indicator results into a single, cohesive JSON array.


5. Response: Finally, the aggregated data is transmitted back to the original caller via the Respond to Webhook n8n node, completing the synchronous data retrieval cycle, making this a reliable and fast n8n workflow.

1. Import Workflow: Import this JSON file directly into your n8n instance. This provides the complete n8n workflow logic, ready for configuration.


2. Alpha Vantage Credential Setup: This n8n workflow requires a Premium Alpha Vantage API Key. Navigate to your n8n Credentials section.


3. Create Credential: Create a new credential of type HTTP Query Auth.


4. Naming: You must name the credential exactly Alpha Vantage Premium (this name is hardcoded across all HTTP Request nodes in the n8n template).


5. Configuration: Set the Query Parameter Name to apikey and the Query Parameter Value to your actual Alpha Vantage Premium API token.


6. Activation: Ensure the n8n workflow is active. The three Webhook nodes will expose the necessary n8n trigger URLs for your calling applications.

Webhook (15min Data, 1hour Data, 1day Data): The primary n8n trigger for their respective data requests. They wait for an external HTTP call and initiate the subsequent parallel API fetches.
HTTP Request (MACD, RSI, BBANDS, SMA, EMA, ADX): Multiple instances of this n8n node are used to query the Alpha Vantage API. They are configured with specific functions (e.g., function=BBANDS) and intervals (e.g., interval=daily) for the symbol TSLA, utilizing the Alpha Vantage Premium credential.
Code (Format Response - ):* These 18 custom JavaScript n8n node functions are crucial for data quality. They standardize the nested, raw Alpha Vantage output by extracting the key data (Technical Analysis: [Indicator]) and trimming the result to only the latest 20 data points, ensuring a lightweight and uniform output structure.
Merge (Merge Indicators): This n8n node consolidates the six parallel data streams from the formatter nodes back into a single item list, preparing the comprehensive data set for final delivery.
Respond to Webhook: The final n8n node in each branch, used to return the aggregated JSON response synchronously back to the system that initiated the original n8n trigger, completing the external API call.
