Tesla Candlestick and Volume Pattern Analysis Agent - n8n Workflow

Financial analysts building automated trading or quantitative systems.
Quant developers needing reliable, structured technical analysis signals.
Users of n8n looking for specialized AI agent architectures for market data.
Individuals seeking advanced n8n templates for integrating LLMs with external APIs.

This specialized n8n workflow serves as a crucial sub-agent within a comprehensive financial market analysis system, specifically targeting the Tesla (TSLA) stock ticker. The primary purpose of this n8n automation is to transform raw financial time-series data into actionable trading signals. It is powered by a LangChain Agent which leverages Alpha Vantage data tools and the reasoning capabilities of OpenAI's GPT models. This dedicated n8n node setup performs complex technical analysis, identifying critical signals such as various reversal candlestick patterns (Hammer, Doji, Engulfing) and volume divergence across 1-hour and 1-day timeframes. The value of this n8n workflow lies in its ability to output a clean, structured JSON analysis, which is essential for systematic trading strategies. This workflow is a perfect example of advanced use cases available in n8n templates.

The operation of this n8n workflow is initiated externally, making it highly modular:

1. Trigger Activation: The process starts with the "When Executed by Another Workflow" n8n trigger. This means a primary parent n8n workflow calls this sub-flow, passing essential context variables like the analysis message and sessionId.


2. Agent Initialization: The input is immediately fed into the "Tesla 1hour and 1day Klines Agent" n8n node. This agent, configured with an expert system message, recognizes its task: analyzing TSLA Klines data.


3. Data Acquisition: The AI agent activates its designated tools. These tools are two Tool HTTP Request n8n nodes: "Candlestick Data Hour" and "Candlestick Data Day," which securely retrieve the latest 1-hour and 1-day OHLCV data for TSLA from Alpha Vantage.


4. AI Reasoning: Data, memory context (via the "Simple Memory" n8n node), and the agent prompt are sent to the "OpenAI Chat Model" n8n node (running GPT-4.1). The model analyzes the data for patterns and divergence signals.


5. Output Generation: The agent ensures the analysis adheres to the strict JSON output format defined in its system prompt, returning the detected patterns, volume signals, and a summary back to the triggering parent n8n workflow.

To deploy and utilize this powerful n8n workflow, follow these setup steps:

1. Import: Import the provided n8n workflow JSON into your n8n instance.


2. OpenAI Credentials: Set up or verify your existing 'OpenAi account' credential, linking it to the 'OpenAI Chat Model' n8n node.


3. Alpha Vantage Credential: You must create an 'HTTP Query Auth' credential in n8n and name it exactly Alpha Vantage Premium. This credential holds the required API key for the 'Candlestick Data Hour' and 'Candlestick Data Day' n8n nodes to execute successfully.


4. Workflow Linkage: Since this flow uses the 'Execute Workflow' n8n trigger, it is designed to run only when explicitly called by another workflow (e.g., a primary analysis dashboard). Ensure the parent n8n workflow passes the required input data (message and sessionId) to successfully activate this n8n template.

This n8n workflow utilizes several specialized nodes essential for AI agent operations:

When Executed by Another Workflow (n8n trigger):
Function: Serves as the activation point for this sub-workflow when called by a parent n8n workflow.
Key Configuration: Configured to accept message and sessionId as workflow inputs.
Tesla 1hour and 1day Klines Agent (LangChain Agent n8n node):
Function: The core reasoning engine. It orchestrates the data retrieval and pattern analysis using the connected LLM and Tools.
Key Configuration: Contains a detailed system prompt instructing it to identify specific reversal candlestick patterns and volume divergence in TSLA data, requiring a strict JSON output.
Candlestick Data Hour / Candlestick Data Day (LangChain Tool HTTP Request n8n node):
Function: Acts as a callable tool for the AI agent, fetching 60-minute and daily TSLA OHLCV data, respectively.
Key Configuration: Uses Alpha Vantage API endpoints and requires the Alpha Vantage Premium credential.
OpenAI Chat Model (LangChain LLM n8n node):
Function: Provides the language processing and reasoning capability, typically running on a powerful model like GPT-4.
1.
Key Configuration: Connected to the 'OpenAi account' credential to perform analysis and structure the final report.
Simple Memory (LangChain Memory n8n node):
Function: Stores short-term conversational context, ensuring the AI agent retains information across multiple analytical steps within a single session.
