### Steps

**1. Find the market**

Through the market list or search. Open the market page — you'll see the current YES / NO price, the order book, the chart.

**2. Pick a side**

The **Buy YES** or **Buy NO** buttons. Share price = probability of the outcome:

* YES 30 cents → the market values the probability at 30%, payout 1 dollar on a YES resolution
* NO 70 cents → the market values NO at 70%, payout 1 dollar on a NO resolution

**3. Fill in the parameters**

In the trade modal:

* **Amount** — how much to spend
* **Estimated shares** — how many shares you'll get at the current price
* **Slippage tolerance** — 5-7%
* **Order type** — Market / Limit

**4. Review fees**

The trade modal explicitly shows:

* Entry amount
* Terminal fee
* Estimated effective price per share
* Estimated max payout
* Net cost

**5. Confirm**

Sign in the Metamask wallet popup.

### Selling before resolution

An open position can be closed before resolution — the market is liquid 24/7 while the order book is alive.

* Open the position in **Portfolio**
* **Sell shares** → trade modal with the reverse operation
* You get the current market price for your shares (YES/NO moved in your favor or against you — that's your PnL)

### If the transaction fails

* **Slippage too low** → the price moved beyond tolerance, raise slippage and try again
* **Insufficient balance** → not enough funds factoring Polygon gas
* **Thin order book at your size** → consider splitting into multiple orders or waiting
* **Network congestion** → retry in a minute
* **Wallet rejected** → make sure you sign with the right wallet

### After opening a position

* The position shows in **Portfolio** with **Open** status
* PnL updates in real time based on the current share price
* You can set a stop / take-profit from the position card
* After the event — status changes to **Resolved**, the **Claim / Redeem** action becomes available

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://bread-5.gitbook.io/bread/predict-terminal/how-to-open-position.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.
