Trade daily/weekly charts? Or trade London sessions only?

I want to specialize in trading very long term, as in using the daily and weekly charts since as a university student I can not afford to stay glued to the monitor at all times looking at the price. However I also hear advice that I shouldn’t be in a trade at all times safe for the London/New york sessions where the volatility is at the highest?

Which one is it? I want to trade long term, I really do. I feel that it’s what those elites like Warren Buffet do for a living. :stuck_out_tongue:

If your aim is to trade long term(holding positions for weeks/months) what happens in a single trading session shouldn’t really matter.
