# Size Platform Guide

Size funds traders in 15 minutes.

You run a Trial on live markets. Finish #1 and you get a Life: a funded account on house capital. Your share of profits becomes a Payout.

You are never risking your own bank account: the most a Trial can cost you is the Key you used to enter. See [What you risk and what you can win](/docs/how-size-works/what-you-risk-and-what-you-can-win.md).

Every Trial also ends with [Your Grading](/docs/playing-a-trial/your-grading.md): how you traded versus the field.

## The path: Key to Payout

```mermaid
flowchart LR
  Key --> Trial --> Life --> Trade --> Payout
```

| Step | Term   | What it means                                |
| ---- | ------ | -------------------------------------------- |
| 1    | Key    | Entry ticket for a Trial that can win a Life |
| 2    | Trial  | 15 minute match on live markets              |
| 3    | Life   | Funded account you win and trade             |
| 4    | Trade  | Open the Terminal on an active Life          |
| 5    | Payout | Withdraw your share of earnings              |

Your Grading sits beside this path. It is feedback after the Trial, not a step you unlock by winning.

## 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://size.club/docs/size-platform-guide.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.
