Understanding the Probability

Large percentage moves in low-volume markets can sometimes be disproportionate to the actual information density. 2. Delta Analysis: The 68.95% change over a 1-hour window represents a rapid realignment of the market price. This often follows a significant information update or a change in the expected roster or starting lineup. 3.
