Fill out order form
After selecting your derivatives contract, your Trade tab layout will update with the selected contract market data along with your order form.
Here you’ll see buy / sell buttons, a dropdown menu allowing you to change the order type, three input boxes, a quantity slider as well as an 'isolate position' toggle. Before we input values into these boxes, knowing how an order type works is necessary.
A market order is meant for immediate execution, as it will match with opposing limit orders that are already available on our order books. Market orders will always incur a slightly higher fee known as a taker fee (the second percent beside your 30 day volume). With market orders you can only input the volume you would like to buy or sell and not the price.
Limit orders will execute at the price you’ve set or better, once the market reaches your limit price. They can be subject to maker or taker fees depending on when it executes. If a matching order already exists and it’s executed immediately, then taker fees will be charged.
On both the market and limit order form you are able to isolate your order / position margin, this allows you to choose the max leverage and hence the funds you will risk on the position. You can learn more about isolated margin and the default cross margin here.
