I trade in New York time session. I find this session more liquid than various sessions. Commonly I take after my plans and start to see the blueprints. If I find any set up I open the trade. If I don't find any set up as showed by my technique and trading outline, I don't open any trade for that day.
Well, I think every time is a good time to trade forex as long as you know what you are doing. When you have no idea about what you are doing, even the so-called best time won’t work. Look for improving your skills instead of looking for the right time!
I think that is an okay thing to do and you can always trade according to your style and preference. The market is open 24 hours and it does offer this advantage to the traders. They can trade anytime during the day or night.
