ExtremePriceHighlighter (EPH) RTX Extension requires the Volume Analysis Package and complements the order flow analysis of the VolumeScope® Package.
EPH operates on the volume-at-price data within each bar and finds the extreme prices over multi-bar periods with options including Last X Days, Last X Bars, and Visible Bars. When Visible Bars is selected, EPH identifies the extreme prices within the visible bars of the chart. The highlighting updates dynamically as you zoom or scroll the chart, or as new bars form in real-time. Highlighting options include Top X, Top X%, Bottom X, and Bottom X%. If EPH is set up to highlight the Top 5% of prices in the visible area, it will compute the number of prices touched in each bar, and sum those values. Specifically, if 20 bars were visible and each had a range of 10 prices (a 10 tick rangebar), then EPH would identify the 5% of the 200 prices with the highest volume; i.e., the ten highest volume prices in the chart would be highlighted.
In addition to volume, the following data options are available: Ask Vol, Bid Vol, Delta, |Delta|, Trades, Avg Size, Price, Buy Imbalance (Diff), Sell Imbalance (Diff), Buy Imbalance (%), and Sell Imbalance (%). When highlighting the Bottom X or Bottom X%, a setting is available to exclude the extreme X prices in each bar. For instance, if "exclude extreme 2 prices" is specified, the highest and lowest prices in each bar will be ignored (not considered for identification) since those are typically the lowest volume prices.
