I think all the Economic news can affect the market, it might not do in grand way, but it all joins the party. The best way to know is by checking Economic Calendar, it is obviously the best way to go. I am very lucky that I have got OctaFX broker, as they have wonderful Economic News calendar, it is in my time zone, so that means I can work out every big news that could affect the market. Also, I use swap free account option, so that means I am not required to worry over long term trade and can continue till any major news releasing, it keeps me in safe and tension free zone, it’s all thanks to this lovely broker.
