My worst time to trade is during news time, when results come because you have anticipated you placing orders but not benefiting you more than 5 pips, I hate news but don't take it personally, maybe to your advantage and I don't agree with the worst time or day especially in forex trading, in my opinion all those days are the worst days in forex trading when you are so worried, your emotions are out of control and your level of greed is high because of any desire. If your luck is not profitable for you today are the worst days in forex trading for you really !!
