INPUT: The system will use the price you entered exactly to fill the orders.

OPPONENT: Orders will be filled using the opposite side's best quote.

For example, if you are opening 10 contracts long, the best buy price is 10 and the best sell price is 11. You will send an order buying 10 contracts at 11. If the order, is not fully filled, the rest will be left on the orderbook.

For example, if you are opening 10 contracts long, the best buy price is 10 and the best sell price is 11. You will be send an order buying 10 contracts at 10.

OVER: The price will be the best opposite quote + overPrice(not a fixed value).

MARKET: The price will be newest price * (1 ± 5%).

For example, if you are opening 10 contracts long, the latest price is 10. Then you will be sending out an order buying 10 contracts at (10 * 1.05)=10.5.
