We have removed the support of any proprietary languages in AlgoStudio in order to make the development process as much clear as possible. Now we support only C# language that has a lot of advantages against previously supported.
By the way we have implemented the new approach to AlgoStudio coding environment & combined it with the most reliable IDE Visual Studio from Microsoft. Now you can create your trading extensions even more convenient and fast.
In case you will face any problems with coding for PTMC, feel free to ask questions on this forum in AlgoStudio branch
I think that it is very big disadvantage that we cannot use metalang4 written indicators and EAs.This language is easy to learn, not many code lines are required to write anything. I cannot find any beginners howto documents and it is for me painful to use it when I have long MT4 experience.
maybe try to prepare web page for converting code like this prepared for Calgo users: http://2calgo.com/
