Two price targets that look identical on a chart can differ significantly in mathematical probability, as the notes at orb trading fifteen minute excel west describe. This range projection method relies on the initial fifteen minute range to set the scale for the rest of the intraday session. Determining the width of the opening range provides a fixed measurement that acts as a ruler for future movement. A small error in measuring the high or low of the first fifteen minutes shifts the entire projection for the day.
Calculating Measured Moves
The mechanics of a range extension involve taking the absolute difference between the session high and the session low established during the first fifteen minutes. Once this value is identified, it is added to the breakout level to find the first target. If the market initiates an opening range breakout, the distance traveled from the opening bell to the high of the range is applied to the low. This creates a projection that follows the logic of a measured move. Using a 15 minute timeframe ensures the data is not skewed by minor noise seen in a 5 minute chart.
Applying the Projections
Price often moves in multiples of the initial width. A one to one extension is the primary target. A two to one extension serves as the secondary target. This math remains consistent through the regular trading hours. If the market opens with high volatility, the width of the orb will be larger, which naturally pushes the targets further away. A tight range during the first hour often leads to more compressed targets, while a wide range suggests a more expansive day. The calculation does not change based on the asset class.
Timeframe Dependencies
The choice of timeframe dictates the precision of the measurement. A thirty minute range provides more stability but offers fewer opportunities for early entries. A sixty minute range captures more context from the market open but results in targets that may not be hit before the closing bell. Most mechanical setups focus on the fifteen minute range because it balances volatility with actionable data. Using a larger timeframe like the 60 minute range reduces the frequency of signals but increases the distance of each projected move.
Execution and Targets
Targets are reached when price hits the calculated level. The projection is a mathematical expectation, not a guarantee of movement. If the market fails to hold the level after an opening range breakout, the projection is invalidated. Monitoring the price action near the session high determines if the trend has enough momentum to reach the second extension. The math is applied to the price levels, not the time of day. The process is mechanical and relies strictly on the math derived from the opening bell activity.
