I never was one for Commodity Perspective ... I just built charts. Good grief, I have an attic full of rolls of paper. Not being a day trader, I feel that drawing in a daily, weekly, and monthly .. high, low, settle, keeps me in synch with the market. Keeping several option months ... (Nov-Nov, May-May, etc.) keeps me out of a lot of markets that would have ripped me apart.
So, I'm a dinosaur with paper, straight edge, and ink.
