I have never tried news trading, so I’d definitely check out the tools you’ve attached. I think new trading is one of the easiest ways to predict the price movements of a certain currency pair.
I have tried to predict the move directions in the past (based on data/expectation) - but still total mess. Market may react bad even on good news. Dunno why, but it's totally mess in past 1-2 years.
This tool helps to catch the move without analyze of the news/results. All I see - just the mark of impact to the Market (take just high impact).
