# Assets

## Selecting assets

When you create an agent, you specify **which assets it should operate on**. There are several ways to do this:

* **Mention them directly in your description** — e.g. "DCA $200 into Bitcoin every Friday".
* **Select them in the chat** through the **Add** → **Assets** button: browse the catalog (10,000+ instruments) and attach them to the conversation.
* **Pick them from your broker** — if you've connected a platform, you can choose the assets available at that broker.

You can **mix asset classes** within a single agent: stocks, cryptos, currencies, indices, futures, ETFs, commodities.
{% endhint %}

## Available asset categories

More than **10,000 instruments** are available, organized by category:

* **Stocks** (Apple, Tesla, Nvidia, etc.)
* **Cryptos** (Bitcoin, Ethereum, etc.)
* **Currencies** (EURUSD, USDJPY, etc.)
* **Indices** (S\&P 500, Nasdaq, CAC 40, etc.)
* **Commodities** (gold, oil, etc.)
* **ETFs**
* **Futures**

The **number of assets per agent** depends on your subscription plan. See [Pricing](/misc/pricing.md).

## Where each asset trades

* In a **backtest**, you tune the per-asset trading conditions (commission, spread, swap fees, leverage) in the **Fees** step, so the simulation reflects realistic costs. See [Backtest an agent](/agents/backtest-an-agent.md).
* In a **demo or live execution**, the agent runs on a **portfolio**. A demo portfolio uses Obside's market data; a real portfolio trades on its connected broker, with that broker's fees and market specifications. See [Portfolios](/portfolios/portfolios.md) and [Run an agent](/agents/run-an-agent.md).
