# Aggregation

Now you can analyze thousands of data points for multiple instruments, companies, ETFs, commodities and any global instrument via our new app called "[aggregate](https://klickanalytics.com/aggregate)". The aggregate app allows you to;

* Create your own list of instruments
* Chose your field to aggregate e.g Close Price, % Change, Volume etc.
* Select historical aggregate via
  * Sum
  * Average
  * Maximum
  * Minimum
  * Count
* On top of it, calculate results for
  * Percentage Change
  * Cumulative Change
  * Difference
  * Ratio
* Define your own time series range

The system will calculate all the time series for each instrument and then apply specified aggregation, and summary calculations to give you historical trend analysis based on your own list of instruments.
