What does the sliding scale in the “HIRO Signal” column indicate? The HIRO Signal column features a sliding scale that represents the 30-day range of HIRO for a given stock or index. The full width of the gauge represents the 30-day range of the HIRO signal. The colored segment, ranging from red to green in color, represents the 5-day range of the HIRO signal. The circle plots today’s HIRO signal vs. the last 30 day and 5 day range. The circle’s color represents today’s flow. Red indicates negative HIRO flow, where traders are selling calls and/or buying puts. A dark red open circle indicates the HIRO signal is near the low of the day. Green indicates positive HIRO flow, where traders are buying calls and/or selling puts. A dark green open circle indicates the HIRO signal is near the high of the day. Yellow indicates a neutral position, meaning HIRO flow is neither overly positive or negative for the day.
