Pre-Market Gap Analysis

The spread costs zero. The analysis provided in the note orb trading crypto against hillary publishes on this covers premarket gap mechanics and the specific way an opening range breakout behaves during the first hour of liquidity. Determining if a gap represents a structural shift or a temporary imbalance requires looking at the volume profile left behind by the overnight session.
Gap Magnitude and Volume Profile

A gap exists when the market open price sits significantly away from the previous session high or low. Measuring the depth of this gap provides the baseline for the day. If the price moves into the gap during the first fifteen minutes, the move is often a mean reversion. If the price stays above the gap, the gap acts as a support level. A large gap on low volume suggests a lack of conviction. A small gap on high volume suggests a heavy repositioning of orders. The relationship between the premarket volume and the opening bell volume dictates whether the move is a continuation or a trap.
The Opening Range Mechanics

The fifteen minute range serves as the primary filter for intraday direction. Once the first fifteen minutes conclude, the high and low of that period define the immediate boundaries. A gap that is immediately breached by the opening range indicates a failed continuation. In these cases, the price often seeks the previous day's close. Conversely, a price that respects the boundary of the fifteen minute range suggests the premarket gap is the new floor. This distinction separates a trend-following setup from a reversal setup.
Measuring Continuation vs. Reversal
A true continuation move maintains the gap through the thirty minute range. If the price spends the majority of the first hour trading back into the premarket price action, the gap is being filled. This filling process is not a sign of weakness but a rebalancing of orders. The thirty minute range provides the first clear look at whether the market intends to hold the new price level. If the session high is set quickly after the market open and then price drifts back, the gap is likely a liquidity grab rather than a structural shift.
Timeframe Alignment
Scalpers look at the 5 minute chart to find entries, but the structural integrity depends on the sixty minute range. Comparing the premarket levels to the sixty minute range helps identify where exhaustion might occur. If the gap is larger than the average daily range, the probability of a gap fill increases. A small gap relative to the volatility of the overnight session usually leads to a clean opening range breakout. Watching the tape during the first hour determines if the gap is being defended or ignored.
