# FAQ

## Do I need to create an account?

No. Browsing needs nothing. Trading needs a wallet and a Lighter account, which is created by your first USDC deposit — there is no sign-up form. See [Your Lighter account](/getting-started/account.md).

## Why is my price slightly different from another site?

Every exchange is its own market. NockTrade shows Lighter's book, because that is where your order actually fills. The same asset on another venue can trade a few basis points away at any moment; showing you their price would be lying about yours.

## Where is my private key stored?

Your Ethereum key stays in your wallet. The trading API key is generated in your browser, stored encrypted in local storage, and never transmitted. NockTrade has no server that holds keys. See [Custody and keys](/concepts/custody.md).

## What does trading cost?

2.0 bps on taker orders, 0.0 bps on maker orders, enforced by a ceiling you sign once. Lighter charges retail zero. Funding is paid between traders. See [Fees](/concepts/fees.md).

## Why do the two enable-trading signatures cost no gas?

Both are message signatures, not transactions: one derives your local key vault, the other authorizes the key registration that is submitted to the rollup. Neither moves funds.

## Why does the Orders tab only show this session?

The venue's full open-orders stream requires an authenticated tier that is not wired in yet. The tab says so explicitly and lists everything placed from this browser session; "Cancel all" still sweeps the whole market, including orders you placed elsewhere.

## Can NockTrade withdraw my funds?

No. Withdrawals only travel to the Ethereum address that owns the Lighter account, and they require your Ethereum key. We never have it.

## A market shows no candles or an empty book. Is it broken?

Usually it is simply new or thinly traded. The terminal labels these states explicitly rather than inventing data.

## Which languages does the interface support?

English, Chinese and Japanese — the globe button in the navigation switches instantly and remembers your choice.

## I found a bug or a number that looks wrong.

Tell us on X at [@NockTrade\_xyz](https://x.com/NockTrade_xyz). A ledger that could ever disagree with a submitted order is our highest-severity bug class.

## 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://docs.nocktrade.xyz/reference/faq.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.
