That's a good idea because all the time markets don't get good movement. So some special time must choose to trade better. Most traders & I also choose overlapping sessions which mean when the London session & New York session are open & according to IST time, 5:30 a.m. to 9:30 p.m. In addition, you can trade Asian opening sessions & safes. Of course the style and size of the account is always important in trading, I usually recommend beginners to watch each session every day because it gives them a horizon that helps them to understand market movements, if they do it the right way with true passion they only get a present coming in the future.
