# Portfolio and Paper Trading

> Driven portfolios track positions, cash, and performance per Agent. Paper trading lets you test ideas with real market data and virtual funds using natural language.

Driven supports portfolios and paper trading so you can test ideas with real market data and virtual funds. This gives your research a place to live: instead of analyzing a stock in isolation, you can hold it in a simulated portfolio, track how the thesis plays out, and let the Agent reason with that context.

## Portfolio

A portfolio tracks cash, positions, orders, and performance. The Agent uses that context when researching opportunities or monitoring risk, so a question like "is this portfolio too concentrated?" has a real answer to work from.

An Agent can run several portfolios at once, and each one is driven by its own [Playbook](/concepts/playbook) — the strategy that sets its universe, risk rules, and trading discipline. That lets one Agent run distinct strategies side by side and compare how each performs.

## Paper trading

Paper trading lets you simulate trades without real money. It is useful for:

* Testing strategy rules before committing capital
* Practicing order workflows
* Tracking research ideas to see how they age
* Comparing the performance of different Agent strategies

Orders use real market data, so the simulation reflects actual prices and movement.

## Placing trades in natural language

You do not fill out an order ticket. You describe what you want:

```text theme={null}
Put 10% of available cash into NVDA in my paper account.
```

```text theme={null}
Cut my AAPL paper position in half and explain the impact on portfolio concentration.
```

The Agent translates that into an order, shows you the portfolio impact, and executes it in the paper account.

## Managing orders

Limit orders are fully managed by the Agent. It can see order IDs and cancel a pending order directly by ticker, so you do not have to drop into the UI to clean up a stuck order:

```text theme={null}
Cancel my open limit order on TSLA.
```

## Current limitation

Paper trading coverage may differ from research coverage. You can research a broader set of markets than you can necessarily paper trade. Before building a workflow that depends on placing trades in a given market, confirm it is supported.
