The world of commodities are connected with zigzags which are just diagonal waves, than can overlap. The VIX is some of the worst diagonal wave structures you will see, with siver getting my second vote. I look for the rough outline first. This has the potential to be a corrective zigzag. It would be nice that next week the VIX will still close that gap below us, after which fear could strike the markets on an even bigger scale. SP500 options make up the VIX, so we can see the extreme violent swings options can produce.
Spikes to the downside can happen in a flash, and usally at the end of a run, so you got to be fast to catch any bottom in the VIX.
