And we are certain, that no one is going to beat Sierra Chart with an identical test in this area. Sierra Chart Volume Profiles are not built from tick by tick data. They are built from the chart bars themselves and the chart bars are built from tick by tick data and internally contain the volume at price data. This is why when you modify Volume Profiles, or draw them by hand, they immediately appear. They are not built from the tick data at that time. If you have a one-year chart built from tick by tick data, with a lot of chart bars, it is not going to immediately reload when changing any of the Chart Settings which affect the bars. They do have to be fully rebuilt from the underlying data file in order to support all of the studies in the chart. Although the underlying data in the data file most likely is cached by the operating system so this can happen relatively fast. One thing that we will do, is we will look at the recent changes we made with building chart bars to see if there are some changes we can make, involving function inlining, which might improve performance slightly.
