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. 

How to install 

The Charting blade is installed as a Service Blade alongside the Caplin Transformer core.
