Does such a wild animal exist nowadays, where I can create and backtest strategies without any programming knowleadge?
Will be forever grateful if somebody can throw me a link or some useful info.
Thanks a bunch 
I have used and still use easy language for what i call rapid prototyping. back testing core ideas and seeing if they work. Yes it is nice, it is pretty powerful, you can have up to 99 separate data streams. It also has basic genetic algorithmic optimization and you could program nearest neighbor automated rule selection if you really wanted to. But if you really want more power then C# is the way to go since you can make your own DLLS. In general i think easylanguage is a good mix of functionality vs ease of use. There are specific limitations though but for a majority of the “non programmers” it will be the best mix you can find. Otherwise you just end up with strat builders in wizards or something and its crap.
The problem of Easylanguage is that you need to buy a platform, or a Tradestation account, for using it.
The best and fastest trading script language is C. It’s also free, you can download a C based automated trade platform from the Internet.
