I was wondering more if there's any charting systems that include live after hours or pre-market trading?
Stockcharts.com doesn't as far as I know and that's what I work off of 95% of the time. I haven't checked in my thinkorswim, I need to do that.
These thoughts are just mine, not right, not wrong, just thoughts. Invest in what you believe in, not what I believe in. Do your research, and invest in the facts.
