# Configuration

## LLM API Keys

Strategy generation and backtest analysis require an LLM. Set at least **one** of the following:

| Variable            | Provider              |
| ------------------- | --------------------- |
| OPENAI\_API\_KEY    | OpenAI (GPT-4o, etc.) |
| ANTHROPIC\_API\_KEY | Anthropic (Claude)    |
| GEMINI\_API\_KEY    | Google (Gemini)       |
| DEEPSEEK\_API\_KEY  | DeepSeek              |
| XAI\_API\_KEY       | xAI (Grok)            |

Any OpenAI-compatible endpoint is supported via [litellm](https://github.com/BerriAI/litellm).

## Network Proxy

If your network requires a proxy to reach LLM APIs:

| Variable     | Description     | Example                 |
| ------------ | --------------- | ----------------------- |
| HTTPS\_PROXY | HTTPS proxy URL | `http://127.0.0.1:7890` |

## Data & Exchange

| Variable                       | Description                         | Default   |
| ------------------------------ | ----------------------------------- | --------- |
| VIBETRADING\_DEFAULT\_EXCHANGE | Default exchange for data downloads | `binance` |

## Using a `.env` File

Create a `.env` file in your project root. The package loads it automatically at import time:

```bash
# .env
OPENAI_API_KEY=sk-...
HTTPS_PROXY=http://127.0.0.1:7890
```

See [`.env.dev_example`](https://github.com/VibeTradingLabs/vibetrading/blob/main/.env.dev_example) for a full template.
