Options

Options Overview

An option allows the buyer the right, but not the obligation, to buy or sell a set quantity or value of a particular asset at a fixed price by a set date.

A Call Option gives the buyer the right to buy an asset at the strike at contract expiry.

A Put Option gives the buyer the right to sell an asset at the strike at contract expiry.

The option buyer pays premium at inception and receives a payout depending on the value of the asset at expiry (cash settled).

Placing Option Orders

1. In the Market tab, select Options

2. Enter your order parameters

   • Type: enter the contract you want to trade: CALL or PUT

   • Side: "+" indicates a LONG/BUY position on the contract selected, "–" indicates a SHORT/SELL position on the contract selected. (Note: a LONG PUT position is a SHORT position on the underlier)

   • Size: The exposure equivalent of your desired asset. Entering 1 means you are trading an option contract for one unit of the underlier.

   • Strike: The option strike price which will determine the payoff at maturity.

   • Unit Price: This is the order limit price which will be entered into the auction. The system feeds a suggested price, which is a theoretical mid price based on Ithaca protocol proprietary pricing model: these prices are not tradable neither are they guaranteeing a fill of entered price. These prices are meant to help anchor a limit price to be entered that may have higher probability of a match. The indicated implied volatility is calculated by the same model.

3. Verify Order Summary

   • Order limit: Order price

   • Collateral requirement: The amount required to be locked so as to ensure that the order enters the auction.

   • Platform fee: Fee to be paid in case of execution.

   • Total premium: The total to be paid net of fees.

4. "Submit to Auction" and approve your transaction in your wallet
