Hello mauricestaples. To answer your question–neither. For a variety of reasons. I suggest that you spend the time learning to set up a Futures ATM Strategy. If you will check Ninja Trader main website-they have weekly Free Classes available for your education. Start with Order Entry 101. For ATM strategies use ATM-101, ATM-201 and ATM-301. These classes are also available on YouTube, However if you attend class you will be able to ask questions. Good luck to you and happy trading.
I wouldn’t recommend using market orders to enter a trade. I would recommend you use LIMIT ORDERS.

Thank you for your help.
