This website is a home of EasyLanguage decompiler
(The one and only. Servicing since 2003)

You can use it to recover lost passwords or protected source code of your studies.

The cost is $1 per kilobyte of original compiled code or $99 per one item for newer (since 2012) .ELD files.

When you decompile easy language code, it is converted from easylanguage (eld, els) to a text file. Check "EL Source Recovery" section in the menu on the left.

It's is very amusing how TS Securities continually lying to their customers. To all of them. Those who lost their source code after poorly written upgrade and seek ways to recover it are told there is no way. Those who need to protect their systems for distribution are taught how simple and user-friendly it is, to export source to "protected" non-reversible ELD document. <Sigh>.

Two weeks ago I upgraded to 7.2 b 1563.
When I went to open my protected strategy
I rec'd the following:

The following file can not be opened since they
are source protected:

I can open any of the TS strategies but not my protected
ones.

I have about 15 strategies, How can open them?

Unfortunately, there is nothing that can be done.
Files that have been 'source protected' exist as binary
tokens. There is no 'text' to display.

If you are software developer, you should not rely on the built-in document protection in Tradestation. If you intend to distribute your EasyLanguage studies in a protected form -- consider developing custom protection.

We have released C++ sources for the simple Dynamic-Link Library which could be used as a basis for building external protection module for EasyLanguage study.

Available for download in "[in]security" section.

25 Feb, 2003

First version of the online decompiler released.



How it become possible?

As it was known, there is no source code stored in ELS (and now, ELD) token-only storage format, which was firstly introduced in Omega Tradestation 2000i. Tradestation compiler keeps all language instructions in it's internal pseudo-code (token) format, which will be never readable again and can be only interpreted by a machine.

However, the compilation process appeared to be reversible and, amazingly, decompiled source looks exactly as the original!

So, if you have your compiled file but lose source - everything is not lost!

We believe our EasyLanguage online decompiler will help numerous traders and software developers, who was in anticipated demand for such source recovery tool.
