I stay out of the market as much as I can. I try not to take risks, if I can.
I go in for the kill, like a hawk on a small animal when the time is right. Its not pretty, but its better to be a hunter than being hunted. I love goading SPX maket makers taking away their ill gotten gains, its a pleasure.
Please read my post " How to pull the rug on SPX market makers".
By the way, tick and volume bars work great for capturing overnight activity so that you don't go blind into the open (if you trade 24 hr markets, that is).
