The design principle is simple and absolute: NFA never takes custody of your money. ### How it works Orders are signed in your own browser, by your own wallet, and settled directly on Polymarket. NFA does not hold a key that can move your funds and never takes possession of your positions. What it adds is convenience: the trade ticket sits right next to the forecast, pre-filled and explicit about price, size, slippage, and fees, so acting on a call is one confirmation rather than a context switch. You can place a **market order** to trade at the current price, or a **limit order** to rest at a price you choose until it fills or you cancel it. {% hint style="info" %} Trading availability follows Polymarket's own regional restrictions. NFA does not change who can trade; it only makes trading the engine's output more direct for those who can. {% endhint %} ### Builder fee NFA attributes a small builder fee on orders placed through it, embedded in the order you sign. It is disclosed on the ticket before you confirm. There are no hidden markups on top of the market price. ### Positions stay yours Everything you hold lives in your own Polymarket wallet. NFA reads your positions from Polymarket's public data to show your portfolio, but it cannot touch them. That is what non-custodial means here: the analysis is NFA's, the funds are always yours. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://nfa.gitbook.io/nfa-docs/trading-and-portfolio/non-custodial-trading.md?ask=&goal= ``` `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.
