I believe for intraday trading of any asset technical’s should be of more appropriate than fundamentals with proper risk management, but one should also closely follow macro events like outcome of OPEC meetings, unrest in major oil producing countries, release of reserve numbers etc for crude.
For Intraday Trading in Crude Oil Technical Analysis works well. Technical Experts believe all news and fundamentals will be shown by chart.
I believe in Technical Analysis. I know few people who are earning by fundamental analysis but they are using it for investing not for Trading
I suggest Technical Analysis for Trading either Intraday or Swing.
