Frequently Asked Questions
Why focus on Non-Commercial traders?
Large speculators (Non-Commercial) tend to be trend-followers and momentum traders. Their positioning often reflects market sentiment and can indicate crowded trades or extreme positioning.
Do extreme percentiles predict reversals?
No. Extreme positioning can persist for extended periods. Historical extremes tell you where we are, not where we're going.
