Hi, what is the binary structure of WL files?
I understand that the wiki explains how WL4 binaries are structured but I cannot seem to decode the structure of the latest WL files.

Thanks

Hi Adrian,

The structure is not documented. But why do you think you need that? There's convenient Bars.LoadFromFile method - check out the QuickRef example.

Hi Eugene, I am aware of this method - however I am interested in constructing my own WL files in the exact same structure as the current version WL files, mainly because of the speed of reading from binary rather than csv data.

In this case, you can simply call its companion SaveToFile method.

Hi Eugene, I am trying to create my own WL files outside of Wealth Lab. Could you please inform me what the binary file structure is?

As I said, the structure is not documented. Whatever you don't find covered in the QuickRef, User Guide and and Development Guide, is not supported.

To create your own WL files outside, reference WealthLab.dll and call SaveToFile (note that your usage will also be unsupported).
