If we understand all the suggestions of the other people as an opinion only everything will be ok.

Just one example: Many people (on Russian forums especially) said that digital filters are the old/dead question and we do not need to develop anything based on the digital filters. And on the same time Russian broker (Alpari) announced on-live training courses on digital filters with EAs (for money of course). So, it is the old question if for free, but if for money ... You understand.

As to ASCTrend system I may say that Igorad (he is the member of our forum and author of many indicators) did very interesting evaluation of this system. It is the best evaluation of ASCTrend system I've seen in my life.
But in Russian language sorry.
