NQ is a little different. The Nadex Price actually moves faster than the price you see on Ninjatrader.
Im not even going to pretend I can explain it to you… Hopefully this article can explain it a little better. https://forum.apexinvesting.com/t/tick-tick-tick-changes-for-us-tech-100-at-nadex-emini-nasdaq-100-futures/2683
However, if you plan on trading the NQ now, because it has moved so far up in price… Everything now will be considered a premium collection trade. And time will have a bigger impact on profits with these trades. (as long as the market keeps going up, or at least remains the above the ceiling of the spreads)
