The market is a bloodsucker, so adopt a system you are comfortable with and leave emotions at the door. I watch price and volume and aim for low risk entries. I don't pick exact tops/bottoms, I just want the cut in-between.
Command those who are rich in this present world not to be arrogant nor to put their hope in wealth, which is so uncertain, but to put their hope in God, who richly provides us with everything for our enjoyment. 1Tim. 6:17
