The market moves most when there are two or more markets
open around the world. The market moves most during the
European and USA sessions.
Most traders can trade during part or all of these two sessions.
When you look at Forex Factory's news calendar you will know
which currencies may be effected by the news during these
major trading times.
The USA market opens at 8:00 am eastern time. Many news
announcements happen between 8:30 and 10:00 am eastern.
I would suggest you start looking at the market at least by 8:00 am.
This way you will be able to have an idea of which currencies has
potential setups then see if the news causes a few currencies to
move in relation to the direction the news moves the market.
I like to use indicators to determine if a currency pair will move
because of the news. When one or more currency pairs moves
because of the news, I let the indicators give me heads up as to
when to enter the market.
By using indicators to trade I have more opportunities to catch
the currencies that are moving because of the news announcements.
The most important thing is that I do not trade the news I just trade
around the time of the news. Then I only take high probability trades.

trying to share.
