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.
Investing since 82. Felt the pain of the 87, 00, and 08 crashes. All fiat money is subject to devaluation. Most trading is now done by HFT-bots trading among each other. Won't chase any stock/ETF. Over 25 years experience as a networking geek.
