Place Your First Trade

Once your wallet is connected and you have trading funds, you're ready to place your first trade.


Select a Market

Step 1: Browse Events

Markets are organized by trading currency. Pick $BILL or $CROSS at the top to view the markets available in that currency. Then narrow further by category (Crypto, Politics, Sports, Macro, Culture) or sort by volume, newest, or ending soon.


Choose a Side and Set your position

Step 2: Pick Your Position

Every market has two sides. For Event Markets, it's Yes or No. For Crypto Markets, it's Up or Down. Select your side, enter the amount you want to spend, and review the estimated Shares and potential payout before confirming.

The buy/sell panel shows the trading currency at the top — markets in $BILL are bought and sold in $BILL, and the same applies to $CROSS.


Execute an Order

Step 3: Confirm & Submit

Hit Buy to submit a Market Order, which fills instantly at the best available price. Prefer to set your own price? Switch to Limit Order — it posts to the orderbook and executes when your price is reached (with 0% Maker fees).

For details, see Order Types and Buy & Sell.

Amount Spent

100 × $0.550 = $55.000

Fee (Taker)

0.500 × 100 × 0.550 × 0.450 = $12.375

Total Cost

55.000 + 12.375 = $67.375

Tip: Fees are higher when the price is closer to $0.500, and lower when the price is closer to $0.001 or $0.999. For more details, see Fee Structure.
