Source: Cboe Insights for the same day expiry participation estimate. The volume share and holding period figures are widely cited approximations rather than measurements. Most retail orders are internalised off exchange, so no regulator publishes a definitive retail share.
Most retail orders never reach a public exchange, so the retail share of volume is an estimate. It runs around 20% of all US equity trading and about 53% of same day expiry SPX options. Retail activity clusters in the fastest instruments.
