How small can price movements be for Nasdaq 100 futures on the exchange?

Summary: Demystifying Nasdaq 100 Futures Tick Size—Practical Insights, Mistakes, and Real-World Examples If you’ve ever stared at the Nasdaq 100 futures order book and wondered, “What’s the smallest price jump I can trade?”—you’re asking about the minimum tick size. In this article, we’ll crack open what tick size really means for Nasdaq 100 futures, walk through real-life trading screens (including my own blunders), and finish with a practical comparison of how international trade rules sometimes echo these precision standards. I’ll pull in regulatory definitions, real exchange rules, and even simulate a chat with a futures pro.

Get comfortable with this “rhythm” by watching the DOM and checking official specs before you trade.

What Problem Does This Article Solve?

The minimum tick size may sound boring, but it’s crucial if you want to:

Place limit orders that actually make sense
Understand why your order isn’t filling when you think it should
Calculate your real risk and profit per trade—every tick matters

The Basics: What Is a Tick Size?

A “tick” is the smallest allowable price movement of a futures contract. The tick size sets the minimum increment by which the price of a contract can change—think of it as the smallest “step” the price can take.
For Nasdaq 100 futures (the classic E-mini and the Micro E-mini, traded on the CME), the tick size is:

E-mini Nasdaq 100 (NQ): 0.25 index points per contract
Micro E-mini Nasdaq 100 (MNQ): 0.25 index points per contract

But don’t just take my word for it. The CME’s official contract specs confirm this.

How much is a tick worth?

- For the E-mini NQ: 0.25 points × $20 = $5.00 per tick
- For the Micro E-mini NQ: 0.25 points × $2 = $0.50 per tick

If you accidentally set an order at a non-tick increment (say, 0.23), the CME will simply reject the order. I still remember my first week trading the Micro NQ—kept wondering why my 0.1 increments weren’t showing up. Rookie mistake!
