It seems that you are trying to implement some kind of trading the news kind of system and for the most part that is not going to work and the reason is that by the time you find out about a particular news powerful people already made their move so the market is already reflecting that particular news and it is too late for you to make profit out of it.

I understand the desire of newbies to try to make even more money than what the market can offer by simply holding your coins but once you have been here for long enough you understand that not only that is the safest path but ironically it is also the one that gives the most profits once you take into consideration all the fees and taxes that you need to pay.
