Range of the entire bar: The width of the full indicator represents the 30-day range of the HIRO signal on a stock or index (Hedging Impact of Real-time Options).  Here, this is represented by the full width of the long gray shape.

Solid colored segment: The width of this section represents the 5-day range of the HIRO signal on a stock or index.  Here, it is represented by a green area.

Open Circle: This shows today’s HIRO signal relative to the last 30 days & last 5 days.  The color of the circle itself relays what the intraday flow is (green positive HIRO signals and red for negative HIRO readings). For instance a dark red circle indicates the HIRO signal is near the low of the day.

Colors:

• Red indicates negative delta flow (traders sell calls and buy puts)
• Green indicates positive delta flow (traders buy calls and sell puts)
• Yellow indicates a neutral position
