File handling¶ A file is some information or data which stays in the computer storage devices. You already know about different kinds of file, like your music files, video files, text files. Python gives you easy ways to manipulate these files. Generally we divide files in two categories, text file and binary file. Exercise Reading and Writing Files. If you did the Study Drills from the last exercise you should have seen all sorts of commands (methods/functions) you can give to files.

Read CSV file as Lists in Python. CSV File Example: Define correct path of the csv file in csv_file variable.

After suffering from several MT4 platform crashes and taking more than 5 minutes to convert a single file I was done with it and decided to code my own implementation for the conversion of the MT4. This is how I came up with the script you see above which you can easily use to make this conversion whenever you need to.

I will now show you how to use this script and talk a bit about the hst file structure. The hst binary file format is actually not a single file format.

There are two versions of these binary type see here depending on whether the data was generated for an old MT4 platform or a new MT4 platform.

Both versions retain a byte header but the old format has the OHLC data within a 44 byte structure while the new data has it in a 60 byte structure. After you do this the script will generate a pandas dataframe which will then go into a csv file with the default pandas formatting.

The data you get is exactly the same as the data you would export from the MT4 history center although some differences in formatting are indeed present. The script also converts the data into a pandas dataframe before exporting so if you know your way around pandas you can already use this loaded data for anything you want to do without the need to save back to a csv file.

Once you have your data in the above csv format you can also easily analyse it using something like R. Once you have your data in R you can also perform all sorts of statistical analysis, you can evaluate things as entropyrandomnessetc.tarfile – Tar archive access It is possible to add a file to an archive using a name other than the original file name, Rather than writing the data to a file, then adding that file to the archive, you can use addfile() to add data from an open file-like handle.
