Overnight Levels vs the RTH Levels That Rule

Why does the RTH session matter so much more? Volume. The overnight session, the ETH session, trades thin. A handful of participants push price around while most of the world sleeps. When the cash market opens for regular trading hours, the crowd shows up. Every level you drew now faces real defense. That is what makes a level strong.

George says it plainly. Only the RTH prints carry weight, so that is where your levels come from.

This flows straight into the No Level, No Trade rule. A weak overnight line is barely a level at all. Trade from it during RTH and you’re guessing. The Strong Levels that anchor the weekly Battle Plan come from RTH, where the volume proves them.

Here’s the rule that saves accounts. Do not draw a Core Strategy level from the overnight session and then trade it during regular trading hours. The volume isn’t there to back it. George repeats this one across years of sessions, and he means it.

He states it flatly. Overnight levels simply do not carry the same weight as RTH sessions from a pure volume standpoint. So he leaves them off the trade list.

Now flip the direction, because the rule is not symmetric. You can trade an RTH level in the overnight session. The overnight book still respects a proven RTH price. George showed exactly this when a well-marked RTH level bounced price hours before the cash open.

Overnight levels don’t earn much credibility. A short list still does. ES E-mini futures trade all night through the Asian and European markets, so a few overnight prices carry real memory. Mark the highest price explored overnight and the lowest price explored overnight. Those two lines matter.

Why do those two hold weight when other overnight levels don’t? Because the overnight high and the overnight low are a peak and a valley. A swing high and a swing low. A break level pair. And it’s the price the world explored across a number of international markets while you slept.

So the morning routine is simple. Wake up, mark your peaks and valleys, and most mornings that just means the overnight high and the overnight low. Add the Initial Balance high and low. Then trade them.

Two more references round out the overnight watch list. The previous day’s RTH opening price acts as a reliable magnet through the overnight session. And when George is forced to keep only one thing from the night, he keeps the highs and lows of Asia and London, plus a clean 30-minute front side.

• Previous day opening: “That previous day opening is always a really good level in the overnight session,” George notes (Apr 30, 2026). Price will hunt it and hesitate there.
• Asia and London highs and lows: “If you made me only pick one thing from an overnight session I’m going to carry forward, it’s the highs and lows of the Asia and London” (Mar 26, 2025).
• 30-minute front sides only: The only overnight level George actually entertains trading is a 30-minute front side, or a break level on a 30-minute chart (Jun 21, 2026). Anything smaller, he leaves off.

Mark the overnight high and low and something useful shows up. The first time price challenges either one during the RTH session, it tends to bounce. First touch, first reaction. That gets even more reliable when the overnight level lines up with another one of your Strong Levels.

The break also pays. When price clears the overnight high with force, George treats it as a defined move already loaded on the chart. Do it with vengeance and there’s a built-in target waiting above.

One more spot to know. A few points underneath the overnight low is what George calls the Hail Mary position. It’s a low-probability, last-ditch long. Not a core setup. You reach for it only when a hard flush snaps below the overnight low and you want a lottery-ticket entry into a snapback.

Here’s the concept that ties the whole session question together. A high or low created outside regular trading hours doesn’t fully count as a level until RTH has tested it. Price touched it overnight, sure. The RTH crowd never voted on it. So you mark the note and you wait.

That untested note is a gift. A level taken only in the overnight session and not yet tested in RTH often produces the sharpest reaction later. George keeps those lines on the chart on purpose, and they pay.

So the rule for carrying levels forward is clean. If RTH already tested a level, it did its job and you can retire it. If RTH never tested it, keep it. That covers halfbacks, session highs and lows, even Sunday openings.

George carries an untested halfback forward without hesitation (Feb 22, 2026), notes every high with its RTH context (Mar 8, 2026), and keeps a Sunday opening only when RTH never retested it (Dec 27, 2025). Same test, every time. This is the discipline behind the Sunday Chart Prep routine.

Holidays and shortened weeks throw traders off. The fix is simple. Treat every half-session and overnight stretch between full days as one long overnight session, and anchor your levels to the last full RTH day. That’s the day the crowd showed up and proved price.

Notice what he pulls from that day. The RTH high, the RTH low, and the RTH halfbacks. The proven RTH structure. Everything that happened in the thin sessions after it gets folded into one overnight blur that doesn’t change the levels. This is the same instinct as reading who controls the market before you take a side. Anchor to real volume. Ignore the noise. And when price wanders into the muddy middle between your RTH levels, Stand Down until it reaches one that counts.
