If I recall you are trading to stay sharp doing something besides sudoku? A guy could do a great deal of looking sharp after 10AM, or even after 2:00 PM, ...and accelerate the process majorly. https://www.elitetrader.com/et/threads/charts-for-no-reason.344272/page-19#post-5563374 More Cowbell.
That's not a true reason to be careful with Oil companies. Certainly Ukraine news could be a major issue for a day or two but the fundamental situation supports $100++ Oil for months even if the War ends. There is a massive supply and logistics issue compounded by the European Nat Gas crisis. Meanwhile, many of these energy companies are making money at a pace far in excess of what the market is crediting them for. So the Risk / Reward is really good as long as you don't take terrible entry points and take stop losses. As long as someone can stomach some short term volatility you can't go too far wrong owning most energy companies these days ( especially in Canadian mid cap and juniors ).
