The regular-session opening gap almost everyone overlooks.
Before you start: No prior concept needed — same idea as NDOG, different session window.
Part of the MY EDGE framework — refined through thousands of hours of chart study.
While everyone watches the 9:30 New York open, most traders completely overlook the gap that forms between the previous day's regular session close and today's open. The RTH Opening Gap is an intraday reference specific to the New York session that can influence price delivery throughout the entire day.

Frequently Asked Questions
What is the RTH Opening Gap?⌄
The RTH Opening Gap is the price gap between the previous regular trading session's close and today's RTH open — an intraday New York session reference that most traders overlook while focused on the 9:30 open itself.
How do I use the RTH Opening Gap during the session?⌄
Mark and classify it (Premium or Discount) right after 9:30 New York time, then track whether price retraces to its 50% level within the first 30 minutes, which is a commonly observed behavior.
How is the RTH Opening Gap different from NDOG?⌄
NDOG is the gap between the prior day's close and today's overnight open, formed around 4:59-6:00 PM; the RTH Opening Gap is specific to the regular trading session, formed at the 9:30 New York open against the previous RTH close.
Does the first FVG after the RTH open matter more than others?⌄
Yes — the first fair value gap that forms after the first 30 minutes of the RTH session carries greater importance than later intraday FVGs, since it's the first imbalance after the regular session opens.
