The first 60 minutes of the RTH session establish the Initial Balance. Everything that happens afterward is measured against it. The IB is not just the first hour's range. It's the day's primary reference frame.
The day's first signal
The IB is where the market does its initial price discovery. Early participants establish a range based on overnight inventory, news, and pre-market conviction. The size of the IB is your first read on what kind of day you're dealing with.
A narrow IB means the market is waiting. Institutions haven't committed. There's uncertainty. These sessions often break out of the IB range later in the day as information develops or larger participants enter. Narrow IBs historically precede range extension.
A wide IB means a lot happened in the first hour. Buyers and sellers were aggressive early. With the range established broadly, the path of least resistance for the rest of the day is often rotation within the IB rather than extending it further. Both sides traded heavily already.
Accepted vs failed
When price breaks above the IB High or below the IB Low, you have two possible outcomes. Reading which one you're in determines your bias for the rest of the session.
What it looks like: Price pushes through the IB High (or Low) and builds new letters above it in the next period. It doesn't snap back immediately. Single prints form below the breakout point. Volume is expanding.
What it means: Initiative buyers (or sellers) have control. The session is extending beyond the IB. This is your direction signal. Trade with the breakout, not against it.
Extension targets: 1x IB range beyond the breakout point. Then 1.5x. Then 2x. These aren't magic numbers but reflect historical tendencies. A 10-point IB that breaks out often extends 10-15 points before finding a new acceptance zone.
What it looks like: Price pokes above the IB High, builds one or two letters there, then snaps sharply back inside the IB. No extension. No single prints building. The new period immediately returns to the IB.
What it means: The market tested higher prices, found no continuation, and rejected. This is the auction failure or "false breakout." Responsive sellers absorbed the breakout attempt. This is a fade setup back toward the IB midpoint or POC.
Entry: Short as price re-enters the IB after the failed break. Stop above the IB High. Target: IB midpoint, then POC, then IB Low.
Pre-market prep with the IB
Mark yesterday's IB High and IB Low before each session. These are your first reference levels of the day. Then check where today will likely open relative to those levels.
Opening inside yesterday's IB: Balanced context. Rotation day more likely. IB extremes as reference for fades.
Opening above yesterday's IB High: Bullish gap. Watch for acceptance above (sustained trade there) or failure back inside. If price opens above the IB High and holds, that level becomes support. If it fails back, short toward the IB midpoint.
Opening below yesterday's IB Low: Bearish gap. Same logic reversed. Hold below = bearish. Recovery above = gap fill attempt.
This takes 2 minutes in the morning. It gives you a structured framework for where the first meaningful levels are before price prints a single tick.
