Initial Balance (IB) Calculation Rule
Two price levels that look identical on a chart can represent entirely different volatility regimes, as the notes at orb trading platform sononline ng describe. A trader identifies the initial balance by marking the highest and lowest price points reached during the first period of regular trading hours. This setup relies on the specific timeframe selected to define the boundaries of the day. Setting a 30 minute range requires marking the high and low established between the opening bell and the thirty minute mark. This process creates a box that dictates how the intraday trend develops.
Defining the High and Low
The mechanical process begins at the cash open. The first step involves observing the price action during the initial volatility surge. For a 30 minute range, the high and low are locked in once the clock hits thirty minutes past the start of the session. A 60 minute range follows the same logic but extends the observation period to the full first hour. These levels do not change once the period concludes. Every tick that occurs after this window is measured against these established boundaries.
The Thirty Minute Calculation
A 30 minute range provides a tighter boundary for the opening range breakout. The high is the absolute maximum price achieved during that window. The low is the absolute minimum price achieved during that same window. If a 5 minute candle breaks above the established high, the breakout is active. This method removes the guesswork from the market open. It treats the price levels as fixed hardware rather than moving targets. A small error in marking the session high during this period shifts the entire day's bias.
The Sixty Minute Calculation
Using a 60 minute range captures more broad institutional flow. This timeframe covers the period from the opening bell through the first hour of activity. The high and low are identified only after the sixty minute mark is reached. This larger window often filters out the noise seen in a 15 minute range. The resulting levels act as support and resistance for the remainder of the day. The logic remains mechanical. The price is either inside the range or outside the range.
Volatility and Range Width
The width of the opening range determines the potential for the day. A narrow range often precedes a significant opening range breakout. A wide range suggests that much of the daily energy was spent during the first hour. This measurement is independent of the overnight session. It only looks at the movement starting from the first tick of the regular session. The data is objective. The high and low are set by the clock and the price, nothing else.
