I recommend 2 charting services which are free and designed for serious charting
Stock charts.com
http://stockcharts.com/h-sc/ui?s=$INDU&p...
the free service of Stockcharts is not really that good for intra-day charts even after the day s over.
BigCharts.com is better for intra-day charts though there is a 15 minute delay in real time

Don't complain about Yahoo's charting service...use a better one
Current charts (both the small ones and the detailed chart) are not showing Jan 31's data, and in the case of DJI, Jan 31 detailed chart prints out Dec 24 data.
Please correct them.
