# Configure your Cassie default trade size per mention

> Set the USDC amount Cassie deploys on every mention, choose from quick-select presets or a custom value, and understand the $6 minimum floor.

Your default trade size is the single most important setting in Cassie — it controls how much USDC the agent commits every time you mention `@cassiedottrade` under a market post. Getting this number right before your first trade means you won't be surprised by a position that's larger or smaller than you intended.

## What the default trade size controls

Every mention triggers one trade. Cassie uses your default trade size as the USDC notional for that trade across whichever venue — Hyperliquid or Polymarket — best fits the signal. Counter and watch positions inherit the same size unless a future override is specified.

## Preset options

During onboarding (Step 4 — Defaults) and in dashboard settings, Cassie offers four quick-select presets:

| Preset    | Best for                                         |
| --------- | ------------------------------------------------ |
| **\$25**  | New users testing Cassie's signal interpretation |
| **\$50**  | Default starting point for most traders          |
| **\$100** | Moderate conviction, established workflow        |
| **\$250** | High conviction, experienced users               |

You can also type any custom amount directly into the amount field. Cassie accepts any value that is a whole or decimal number.

## Minimum trade size

The absolute minimum is \**$6 USDC**. Cassie will reject any value below this floor at the settings level — you'll see the message *"Default trade size must be at least $6."* if you try to save a smaller amount.

<Tip>
  Start with **\$25** while you learn how Cassie reads tweet signals. You can always increase the default once you've seen a few trades execute and you're comfortable with the agent's interpretation of different market contexts.

## Where to change your default trade size

<Steps>
  <Step title="During onboarding">
    On **Step 4 — Defaults**, select a preset or type a custom amount, then click **Save & continue**. This is the fastest path on first setup.
  </Step>

  <Step title="From the dashboard">
    After onboarding, open the **Settings** panel in the dashboard sidebar. Update the trade size field and save. Changes take effect on the very next mention.
  </Step>
</Steps>

## How the default applies to each mention

```text theme={null}
You tweet: "@cassiedottrade trade this"
          ↓
Cassie reads the signal from the parent tweet
          ↓
Cassie selects venue (Hyperliquid or Polymarket)
          ↓
Cassie places a trade for your default trade size in USDC
```

There is no per-mention override syntax today — every mention uses the default. If you want to adjust size for a particular trade, update the default before posting the mention, then change it back afterwards.

## Wallet balance requirement

Your wallet must hold **at least your default trade size** in USDC for a trade to execute. If the available balance is below the default, Cassie skips the mention rather than trading a partial amount.

<Note>
  Cassie does not split a trade across multiple smaller executions. If you set a $100 default but only have $60 in your wallet, the trade will not execute. Top up your wallet first.
