Buying options

Options fill instantly at the live quote. There are two ways to place an order: the order panel on a stock page (desktop and tablet), and the quick-buy popup (Home, and the docked bar on phones).

The order panel

Select a contract from Quick trade or the chain and the panel fills in:

Element	What it shows
Title	The trade and date, for example “Above $770 · Sep 24”. “No trade selected” until you pick one. The first Up trade is preselected.
Outlook / Instrument	The outlook chip and the leg, for example “Buy $770 Call · Sep 24”. Two-leg trades list both legs.
Amount	Toggle Contracts (default, starts at 1) or Dollars. The other unit shows alongside (”= $1.23” or ”= 4.07 contracts”). Dollars convert to contracts at the ask, rounded to 0.01.
Readouts	Cost, Max loss, Max profit (“Uncapped” for calls and two-sided trades), Breakeven or Breakevens, % chance ITM, and Wallet “$X USDG”.
Payoff	A chart of profit and loss at the close, with a strip showing Max loss, Break even, and Max profit. Drag the chart to read “Profit at $X”.
Button	Buy $4.92. It reads Sign in to trade when signed out, Deposit to buy when the cost exceeds your wallet, Placing… while it fills, or Coming soon for Neutral.

On success the button turns green with Bought for $4.92, then the take box appears (see Profiles & social). On failure the server’s message shows in red. Opened from Home’s option cards and from the phone bar. It always uses the nearest expiry.

Pick a direction

Tabs Up, Down, or Up or Down (a call and a put together).

Pick a row

Three rows such as “Above

770.00" with a distance tag ("▲

4.57”) and the per-contract price.

Pick an amount

Chips **

1 /

5 /

10** (opens on

5) or type an amount. Contracts are the amount divided by the price, rounded down to 0.01, so you are never charged more than you entered.

Buy

Read the summary line, for example “Max loss

4.92 · profit above

771.23”, and tap ▲ Buy above $770.00 ·$ 4.92. The footer reads “Bought for $4.92 — settles at the close”.

Other footer lines you may see: “Enter at least $1.00”, “Closed for the last 15 minutes of the session”, “Not quoting right now”, “Couldn’t load prices — try again in a moment”, or your Wallet balance.

Limits and rules

Rule	Value
Maximum per buy	$100 of premium. Over that: "One buy is capped at$ 100 for now (this one is $X).”
Minimum	0.01 contracts and $0.01 of cost. The popup requires$ 1.
Legs	Up to two, each a buy: a single call or put, or a call and put together.
Order type	Market only, at the current ask. No limit or stop orders.
Buying power	The USDG in your wallet. The premium leaves your wallet immediately.
Price protection	The server re-quotes at the moment of the buy. If the cost rose more than 2% since you saw it, the buy is refused: “Price moved: $X now, you saw$ Y.” A lower price fills at the lower price.
Stale prices	No quote is offered if the on-chain price is more than 15 seconds old.
Partial fills	None. A buy is all or nothing, and a failed buy takes nothing.
Fees	None.
