Do You Trade 3 Minute Charts? What’s the Correlation Between Time and Trading?

For years I have watched e-mini traders in sheer bewilderment as they preach price action then slap a 3-minute chart on the computer screen. My question is always the same; what does time have to do with e-mini trading if price action is the key to success? Of course I usually get a shrug and a comment like, «that’s how I learned to trade.»
