I wanna buy WLD4.0 after one month trial and click the link "Buy Now!" in Reminder window. However the link does not work, http://wl4.wealth-lab.com/cgi-bin/WealthLab.DLL/getpage?page=WLD3.htm

Would you show me another way of payment?

Click the Products link in the menu above and click a "Price and License" link. In short, non-US customers can buy Version 5 and for a limited time get a key to Version 4 as a bonus.

Thank you for prompt reply.

The link is only work for Purchasing Version 5. But it's good to get a modern version and just wanna know more about the Version 5.

1. Is Pascal based WealthScript in Version 4 also available in Version 5?
2. I have only User Guide of Version 4, are the functions in Version 5 similar to Version 4? or where can I get the User Guide of Version 5?

1. No.
2. WL5 is a whole new, modern product. Scripting is in C#, runs much faster, but logically similar. The transition is not hard.

Download a copy of Version 5.1 and give and try it free for 30-days.

Thanks for your advice,Cone!!

I have downloaded and installed Version 5 and want more information in using this.

It is easy to find the Data Providers, User Guide and WealthScript Guide for Version 4. Would you show me the way to get these products for Version 5?

Besides, I can get the User Guide in 'Help' in WLD 5 and is there PDF format for print out?

The Guides are in the Help menu. All known Data Providers are installed with the product, but if you go to the "Extensions" section of the site, you'll find everything logically organized. In the future (next year), we'll support streaming adapters for IQFeed, ESignal, and QuoteTracker.

Wealth-Lab Pro 5 User's Guide (PDF, 204 pages) can be found at Fidelity's site here. It means there's some WLP specific you'd need to sift out if you're a Developer user.

Do you mean Version 5 gets data from ASCII Files, MataStock Format Data, MSN, WL4 Files and Yahoo!Finance only?

As a beginner, I wanna buy Version 4 at these moment and upgrade to Version 5 later. But I cannot find the way to purchase Version 4.

I tried "Product" -> Price & License, but no link to purchase. then I tried Product-> Wealth-lab 4 -> Purchase. but only Wealth-Lab5 purchase available.
Surely, I tried the link in "Key Eepired" window of trial version of WLD 4, but the link is wrong.

Would you show me to way?

Currently, these are the list of supported data feeds because WL5's functionality is released in phases.

A couple of others are listed in the WL5 Wiki FAQ:
Are there any 3rd party data providers for use with Wealth-Lab Developer 5.1?

WL4 is no longer for sale. Moreover, it makes better sense to start just with WL5 for the following reasons: WL4 isn't going to be updated and fixed, it won't be supported forever, the language (Pascal-based) is different from C# used in WL5 etc. The only option (for a limited time) is to get a free WL4 unlock key with a purchase of WL5.
