## Step 1 — Sign In

Visit [probly.com](https://probly.com) and click **Log In** or **Sign Up**. Choose either:

* A crypto wallet — **MetaMask**, **Coinbase Wallet**, **Phantom**, or **Uniswap Wallet**
* **Email** — Privy creates an embedded wallet for you

See [Sign Up & Wallet](/get-started/sign-up-and-wallet.md) for details.

## Step 2 — Deposit USDC

Trading uses **USDC**. Open **Wallet → Deposit**, copy your deposit address, and send USDC from an external wallet or exchange.

{% hint style="info" %}
Minimum deposit is **10 USDC**. Most deposits confirm within a few minutes.
{% endhint %}

See [Deposits & Withdrawals](/get-started/deposits-and-withdrawals.md).

## Step 3 — Pick a Market

Browse active markets — crypto, sports, politics, and more. Each market page shows:

* The question and how it resolves
* The deadline
* Current **YES / NO** prices (in ¢)
* Recent activity and volume

> Example: *"Will BTC reach $100k this week?"* might show **YES 32¢ / NO 68¢** — an implied **32%** chance.

## Step 4 — Buy YES or NO

On the market page:

1. Click **YES** or **NO** based on the side you want
2. Choose **Market** (fills instantly) or **Limit** (you set the price)
3. Enter the amount:
   * **Market Buy** — USD amount (e.g. $50)
   * **Market Sell** — number of shares
   * **Limit** — price + shares
4. Review the order panel:
   * **Order Value** — shares × price
   * **Est. Fee** — the taker fee estimate
   * **Total** — Order Value + Est. Fee, the exact amount that leaves your wallet
   * **To Win** — total payout if your side wins (shares × $1.00 — **includes your stake**, not just profit)
5. Click **Buy** or **Sell** to confirm

{% hint style="success" %}
Minimum order = **5 shares**.
{% endhint %}

{% hint style="info" %}
Placed a **Limit** order and nothing happened? That's expected — a limit order rests in the book until someone trades against it. Check **Portfolio → Open Orders** to see its status or cancel it.
{% endhint %}

## Step 5 — Track or Sell

Find your position under **Portfolio → Positions**:

* **Hold** until the market resolves
* **Sell** anytime before the deadline — market sell at the best bid, or limit sell at your chosen price

> **Example.** You buy **100 YES** at 60¢ — about **$60** in (exact total shown in the order panel):
>
> * If YES wins → you receive **$100**
> * If YES loses → the shares settle at **$0**
> * If you sell before resolution → you receive *sale price × shares*

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.probly.com/get-started/first-trade.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
