# Quick Start

## Setup

Install and set your LLM API key:

```bash
pip install vibetrading
export OPENAI_API_KEY=sk-...   # or ANTHROPIC_API_KEY, GEMINI_API_KEY, etc.
```

## Generate a Strategy

```python
import vibetrading.strategy

code = vibetrading.strategy.generate(
    "BTC momentum strategy: RSI(14) oversold entry, SMA crossover confirmation, "
    "3x leverage, 10% position size, 8% take-profit, 4% stop-loss",
    model="gpt-4o",
)

print(code)
```

## Backtest

```python
import vibetrading.backtest
import vibetrading.tools

data = vibetrading.tools.download_data(["BTC"], exchange="binance", interval="1h")

results = vibetrading.backtest.run(code, interval="1h", data=data)

if results:
    metrics = results["metrics"]
    print(f"Return: {metrics['total_return']:.2%}")
    print(f"Sharpe: {metrics['sharpe_ratio']:.2f}")
    print(f"Max Drawdown: {metrics['max_drawdown']:.2%}")
    print(f"Win Rate: {metrics['win_rate']:.2%}")
```

## Analyze Results

Use an LLM to evaluate backtest performance:

```python
report = vibetrading.strategy.analyze(results, strategy_code=code, model="gpt-4o")

print(f"Score: {report.score}/10")
print(report.summary)

for s in report.suggestions:
    print(f"  → {s}")
```

See [Backtest Analysis](/library/backtest-analysis.md) for full details.

## Use the Prompt Template with Any LLM

Don't want to use the built-in generator? Use the prompt template directly with any LLM client:

### OpenAI

```python
import openai
import vibetrading.strategy

messages = vibetrading.strategy.build_generation_prompt(
    "BTC grid strategy with 0.25% spacing, 72 levels per side, 5x leverage",
    assets=["BTC"],
    market_type="perp",
    max_leverage=5,
)

response = openai.chat.completions.create(model="gpt-4o", messages=messages)
strategy_code = response.choices[0].message.content
```

### Anthropic

```python
import anthropic
import vibetrading.strategy

messages = vibetrading.strategy.build_generation_prompt("SOL scalping with VWAP and RSI")

client = anthropic.Anthropic()
response = client.messages.create(
    model="claude-sonnet-4-20250514",
    max_tokens=4096,
    system=messages[0]["content"],
    messages=[{"role": "user", "content": messages[1]["content"]}],
)
strategy_code = response.content[0].text
```

## Validate Generated Code

Check generated strategy code for common errors before running:

```python
import vibetrading.strategy

result = vibetrading.strategy.validate(strategy_code)

if result.is_valid:
    print("Strategy passed validation")
else:
    print(result)
    feedback = result.format_for_llm()
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.vibetrading.dev/getting-started/quick-start.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
