The HIRO page displays a summary card in the top-right area of the page showing the current HIRO reading in context of its 30-day range. This lets you quickly judge whether today's options flow is elevated, suppressed, or normal relative to recent history.

A similar gauge also appears in the Stock Screener column for each symbol. In both cases:

• The full width of the gauge represents the 30-day HIRO range
• The colored inner segment represents the 5-day range
• The dot shows today's reading relative to both ranges

High readings (dot near the right/green end) suggest options flow is elevated — these are conditions where gamma levels tend to exert more influence on price. Low readings suggest flow is light and gamma levels may have less impact.

Use this alongside the Options Impact gauge in EquityHub to identify which stocks are most likely to respect their gamma levels on a given day.
