What is an HST file?

HST files mostly belong to MetaTrader 4.

An HST file is not one uniform format but a label applied by different programs to store historical log or trace data.
For example, in MetaTrader 4 the file holds trading and forex data to record past price movements and trade executions. Other applications use the same extension for different purposes:

  • MetaTrader History Files: These files log market data for analysis. Use MetaTrader 4 to open and view them. See the MetaTrader 4 website for more details.
  • SCADA Trend Data: Some systems like Citect SCADA store operational trends in HST files. They serve to track and review system performance. More information is available at the CitectSCADA support page.
  • Data Logger Files: Tools such as Danfoss HST Tools create files that record data in applications like refrigeration systems and environmental monitoring.
  • 3D Image or Historical Records: In other cases, a HST file may be used to store data related to historical images or actions, as seen with files linked to resources like the Hubble site (Hubble Site).
  • Print Job and Game Archives: Certain software, for example Papyrus Client or game advisors, generate HST files to preserve configurations, print jobs, or even saved game states (sometimes using ZIP compression).
  • Database Logs: A few HST files use internal file formats like SQL or Microsoft Compound to archive historical or optimization data from various software applications.

FilExt.com tip: This file’s format depends on its origin, so it is key to use the specific application that created it for accurate viewing and handling. Checking the file header or related documentation can help determine its exact purpose.

How to open an HST file

You need a suitable software like MetaTrader 4 to open an HST file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your HST file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a HST file directly in the browser:. Just drag the file onto this browser window and drop it.

HST format details:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. File extension, signature and file format must match; otherwise errors will occur when the file is opened. So you need a detailed analysis of a file to find out the format and the associated program.
