Using Spectrum Profile

The Spectrum Profile is a histogram that shows the percentage of ticks at each price within the trading range of the instrument. A horizontal bar is drawn at each price level. The total length of this bar reflects the total tick volume at a price. Each bar is further divided into colored bars (Spectra) reflecting what subset of the tick volume occurred during what part of the day. Spectra can represent any amount of time, but the default is 30 minutes. Spectrum Profiles are best used in conjunction with the Market Profile. The Market Profile provides a key to the colors of the Spectrum Profile.
