"Many traders seem to use data on the economy, interest rate curves, volume or other things to decide where prices in their markets will go. I just look at the price and let all that other data be what it is. It may or may not influence prices, but if I just concentrate on prices, I’m tying my actions to the one thing that either makes a profit or loss in my portfolio. There’s less likelihood of being out of step with whatever the market is currently doing."
