This is a continuation of Trading Systems Research for February Part II
We discussed in our daily reports in January on a regular basis the way the market "dies out" in the afternoon. We continue to quantify this behavior with a study of range expansion based on the one-minute charts in the E-mini Nasdaq.

We measured the range expansion each day from 12:00 noon to 4:00 pm EST from the original range from 9:30 am - 12:00 noon EST and generated a monthly average for this number. December 2025 and January 2026 were the lowest numbers going back to August 2021. August 2021 was the only number that was lower.
The compression of ranges seems to be the potential result of option selling. You have to wonder how crowded the option selling trade is for 0 DTE or if it is a trend that will continue to a new all-time low in the VIX.
