This commit implements a comprehensive solution for separating embedding
and chat model configurations, enabling flexible provider combinations
and graceful handling of embedding failures.
## Problem Statement
Previously, the TradingAgents memory system used the same backend_url for
both chat models and embeddings. This caused critical failures when:
- Using OpenRouter for chat (doesn't support OpenAI embedding endpoints)
- Using Anthropic/Google for chat (don't provide embeddings)
- The embedding endpoint returned HTML error pages instead of JSON
- Users wanted to mix providers (e.g., OpenRouter chat + OpenAI embeddings)
Error example:
AttributeError: 'str' object has no attribute 'data'
# Caused by: OpenRouter returned HTML page instead of embedding JSON
## Solution
Implemented three key features:
1. **Separate Embedding Client Configuration**
- New config parameters independent of chat LLM settings
- embedding_provider: "openai", "ollama", or "none"
- embedding_backend_url: Separate API endpoint
- embedding_model: Specific model to use
- enable_memory: Boolean flag to enable/disable memory
2. **Multiple Provider Support**
- OpenAI: Production-grade embeddings (recommended)
- Ollama: Local embeddings for offline/development
- None: Disable memory system entirely
3. **Graceful Fallback**
- System continues when embeddings fail
- Comprehensive error logging
- Memory operations return empty results instead of crashing
- Agents function without historical context when memory disabled
## Changes
### Core Framework
- tradingagents/default_config.py: Added 4 new embedding config params
- tradingagents/agents/utils/memory.py: Complete refactor with error handling
- tradingagents/graph/trading_graph.py: Separated embedding initialization
### CLI/User Interface
- cli/utils.py: Added select_embedding_provider() function
- cli/main.py: Added Step 7 for embedding provider selection
### Documentation (New Files)
- docs/EMBEDDING_CONFIGURATION.md: Complete usage guide (381 lines)
- docs/EMBEDDING_MIGRATION.md: Implementation details (374 lines)
- CHANGELOG_EMBEDDING.md: Release notes (225 lines)
- FEATURE_EMBEDDING_README.md: Branch overview (418 lines)
### Testing & Verification
- tests/test_embedding_config.py: Comprehensive test suite
- verify_config.py: Simple config verification script
## Example Usage
```python
# OpenRouter for chat, OpenAI for embeddings
config = {
"llm_provider": "openrouter",
"backend_url": "https://openrouter.ai/api/v1",
"deep_think_llm": "deepseek/deepseek-chat-v3-0324:free",
"embedding_provider": "openai",
"embedding_backend_url": "https://api.openai.com/v1",
"embedding_model": "text-embedding-3-small",
"enable_memory": True,
}
```
## Backward Compatibility
✅ 100% Backward Compatible - No breaking changes!
Existing configurations work without modification. Smart defaults
applied when embedding settings are omitted.
## Testing
- All core files pass diagnostics with no errors
- Configuration verification script passes all checks
- Supports scenarios: OpenRouter+OpenAI, All Ollama, Disabled Memory
- Graceful fallback tested for invalid URLs and missing API keys
## Benefits
- Enables using OpenRouter/other providers for chat
- Reduces costs (can use local embeddings or disable memory)
- Improves reliability (graceful degradation on failures)
- Maintains full backward compatibility
- Comprehensive documentation and examples
Fixes: OpenRouter compatibility issues
Closes: Embedding/chat provider coupling
Implements: Graceful fallback for memory operations

TradingAgents Framework
TradingAgents is a multi-agent trading framework that mirrors the dynamics of real-world trading firms. By deploying specialized LLM-powered agents: from fundamental analysts, sentiment experts, and technical analysts, to trader, risk management team, the platform collaboratively evaluates market conditions and informs trading decisions. Moreover, these agents engage in dynamic discussions to pinpoint the optimal strategy.
TradingAgents framework is designed for research purposes. Trading performance may vary based on many factors, including the chosen backbone language models, model temperature, trading periods, the quality of data, and other non-deterministic factors. It is not intended as financial, investment, or trading advice.
Our framework decomposes complex trading tasks into specialized roles. This ensures the system achieves a robust, scalable approach to market analysis and decision-making.
Analyst Team
- Fundamentals Analyst: Evaluates company financials and performance metrics, identifying intrinsic values and potential red flags.
- Sentiment Analyst: Analyzes social media and public sentiment using sentiment scoring algorithms to gauge short-term market mood.
- News Analyst: Monitors global news and macroeconomic indicators, interpreting the impact of events on market conditions.
- Technical Analyst: Utilizes technical indicators (like MACD and RSI) to detect trading patterns and forecast price movements.
Researcher Team
- Comprises both bullish and bearish researchers who critically assess the insights provided by the Analyst Team. Through structured debates, they balance potential gains against inherent risks.
Trader Agent
- Composes reports from the analysts and researchers to make informed trading decisions. It determines the timing and magnitude of trades based on comprehensive market insights.
Risk Management and Portfolio Manager
- Continuously evaluates portfolio risk by assessing market volatility, liquidity, and other risk factors. The risk management team evaluates and adjusts trading strategies, providing assessment reports to the Portfolio Manager for final decision.
- The Portfolio Manager approves/rejects the transaction proposal. If approved, the order will be sent to the simulated exchange and executed.
Installation and CLI
Installation
Clone TradingAgents:
git clone https://github.com/TauricResearch/TradingAgents.git
cd TradingAgents
Create a virtual environment in any of your favorite environment managers:
conda create -n tradingagents python=3.13
conda activate tradingagents
Install dependencies:
pip install -r requirements.txt
Required APIs
You will need the OpenAI API for all the agents, and Alpha Vantage API for fundamental and news data (default configuration).
export OPENAI_API_KEY=$YOUR_OPENAI_API_KEY
export ALPHA_VANTAGE_API_KEY=$YOUR_ALPHA_VANTAGE_API_KEY
Alternatively, you can create a .env file in the project root with your API keys (see .env.example for reference):
cp .env.example .env
# Edit .env with your actual API keys
Note: We are happy to partner with Alpha Vantage to provide robust API support for TradingAgents. You can get a free AlphaVantage API here, TradingAgents-sourced requests also have increased rate limits to 60 requests per minute with no daily limits. Typically the quota is sufficient for performing complex tasks with TradingAgents thanks to Alpha Vantage’s open-source support program. If you prefer to use OpenAI for these data sources instead, you can modify the data vendor settings in tradingagents/default_config.py.
CLI Usage
You can also try out the CLI directly by running:
python -m cli.main
You will see a screen where you can select your desired tickers, date, LLMs, research depth, etc.
An interface will appear showing results as they load, letting you track the agent's progress as it runs.
TradingAgents Package
Implementation Details
We built TradingAgents with LangGraph to ensure flexibility and modularity. We utilize o1-preview and gpt-4o as our deep thinking and fast thinking LLMs for our experiments. However, for testing purposes, we recommend you use o4-mini and gpt-4.1-mini to save on costs as our framework makes lots of API calls.
Python Usage
To use TradingAgents inside your code, you can import the tradingagents module and initialize a TradingAgentsGraph() object. The .propagate() function will return a decision. You can run main.py, here's also a quick example:
from tradingagents.graph.trading_graph import TradingAgentsGraph
from tradingagents.default_config import DEFAULT_CONFIG
ta = TradingAgentsGraph(debug=True, config=DEFAULT_CONFIG.copy())
# forward propagate
_, decision = ta.propagate("NVDA", "2024-05-10")
print(decision)
You can also adjust the default configuration to set your own choice of LLMs, debate rounds, etc.
from tradingagents.graph.trading_graph import TradingAgentsGraph
from tradingagents.default_config import DEFAULT_CONFIG
# Create a custom config
config = DEFAULT_CONFIG.copy()
config["deep_think_llm"] = "gpt-4.1-nano" # Use a different model
config["quick_think_llm"] = "gpt-4.1-nano" # Use a different model
config["max_debate_rounds"] = 1 # Increase debate rounds
# Configure data vendors (default uses yfinance and Alpha Vantage)
config["data_vendors"] = {
"core_stock_apis": "yfinance", # Options: yfinance, alpha_vantage, local
"technical_indicators": "yfinance", # Options: yfinance, alpha_vantage, local
"fundamental_data": "alpha_vantage", # Options: openai, alpha_vantage, local
"news_data": "alpha_vantage", # Options: openai, alpha_vantage, google, local
}
# Initialize with custom config
ta = TradingAgentsGraph(debug=True, config=config)
# forward propagate
_, decision = ta.propagate("NVDA", "2024-05-10")
print(decision)
The default configuration uses yfinance for stock price and technical data, and Alpha Vantage for fundamental and news data. For production use or if you encounter rate limits, consider upgrading to Alpha Vantage Premium for more stable and reliable data access. For offline experimentation, there's a local data vendor option that uses our Tauric TradingDB, a curated dataset for backtesting, though this is still in development. We're currently refining this dataset and plan to release it soon alongside our upcoming projects. Stay tuned!
You can view the full list of configurations in tradingagents/default_config.py.
