The data for our charts should be updated continuously throughout the trading day. There are three common reasons you might see charts with old, out-of-date quotes on them:

1. You are looking at a chart with a user-defined range setting where the end date is in the past. Check the "Range" settings for the chart to see if that is the case. We recommend using one of the "Predefined" range settings for charts that you always want us to update.
2. Your browser has stored an old version of the chart in its temporary file cache. Try clearing your cache. Directions
3. The stock you are charting has stopped trading.
