Installing the Charting Service

The Charting blade is designed for use with Intraday data and can perform the following tasks:

  • Request any field at regular intervals.
  • Cache those field value in a file where they can be used to provide charting data.
  • Perform simple validation. For example, you can check a last trade update is within a certain percentage of the previous value (those that are not are taken as erroneous trades), or reject a last trade price that has a value of 0 (which is part of start-of-day processing).

There are Charting blade tutorial pages that explain how to perform these tasks by configuring and using the blade's configuration files.
