# Placing a trade

> Backing an outcome, betting against it, and taking profit early.

Three moves. Everything else is a combination of them.

## Backing an outcome

You think something will happen, so you buy it.

Yes is trading at 40 cents. You put in \$40 and receive about 100 shares.

* **It happens** — every share pays \$1. You receive \$100.
* **You take profit first** — sell at whatever the price is then.

Your position is straightforward: what you put in is what's at stake, always. There's no borrowing, no margin, and no way for a position to cost you more than you committed to it.

## Betting against an outcome

You think something *won't* happen.

In a two-outcome market that's simple — betting against Yes means buying No.

With three or four outcomes, Numera handles it in one step. Choose "against A" and it assembles a position across B, C and D for you. Since exactly one outcome must win, that position pays out whenever A doesn't.

You see one price and make one choice. The assembly happens underneath.

## Taking profit early

Sell any part of your position, any time before the deadline.

Bought at 30 cents and it's now 70? Sell and bank the gain. Want to lock in some upside but stay in the market? Sell half. There's no penalty for closing early, no minimum holding period, and no waiting for the event to finish.

<Note>
  This is the real advantage over a traditional betting pool, where your stake is committed the moment you place it. On Numera your position has a live value you can act on at any time.

## Good to know

<AccordionGroup>
  <Accordion title="How large trades are priced" icon="chart-line">
    Price moves as you buy, so a large order fills across a range rather than all at the opening quote. That's how the market stays balanced.

    Numera calculates your real total in advance and shows it before you confirm, so the number you approve is the number you pay. In well-traded markets the difference is small; in newer ones it's more noticeable, and the preview tells you either way.
  </Accordion>

  <Accordion title="Your price is protected" icon="shield-check">
    You approve a specific price. If the market moves between your approval and the trade landing, Numera won't fill you at a worse one — the trade simply doesn't go through, and nothing is charged. Refresh and you'll see the current price.

    It's a guardrail: you always get the deal you agreed to, or no deal.
  </Accordion>

  <Accordion title="Trade sizes" icon="ruler">
    There's a small minimum on new trades, since Numera covers the blockchain cost of each one.

    Closing a position is always available regardless of size, so you can exit any position at any time.
  </Accordion>

  <Accordion title="Positions stay with your account" icon="lock">
    Positions aren't transferable between accounts. Keeping them in place is part of what keeps them unlinkable — see [privacy](/concepts/privacy). To move value, sell and buy again.
