Market Observation - The industry has discovered that open interest (OI) is calculated bi-directionally [1] - Individual's position accounts for 10%-15% of the open interest (OI) in some contracts [1] - If OI is calculated bi-directionally, the individual's position would account for 20%-30% [1] - The industry's understanding of OI/MC data may be flawed due to the bi-directional calculation [1] Data Correction - Previously used OI/MC data may need to be divided by 2 to reflect the actual situation [1]
