I don't understand what you mean by "how long this could be useful in forex trading updates regarding currency pair". It is a newsreader. I show only the clocks (for sessions) and the news. Since it is attached to GBPJPY to get lots of ticks I am not interested in the technical analysis extra functions so disable showing them. My guess is the vendor will sell this newsreader app but until then, it is an excellent free newsreader and gets news just as fast as any other newsreaders I have tried. Hope this helps clarify?
