 +====== Why Aren't My Volume-Based Indicators Updating? ======
 +Volume-based indicators are updated when each time period is complete. For daily charts, this means volume-based indicators are updated after the market close. Similarly, volume-based indicators on 30-minute charts are updated at the end of each 30-minute period. Price and volume data are both subject to change prior to a period'​s end. Waiting for definitive data ensures that the volume-based indicators are based on correct - and unchanging - data.
 +The example above shows Cisco (CSCO) gapping down on big volume. On Balance Volume (OBV) should be moving lower, but the chart shows an advance over the last few days. This is because the indicator has yet to be updated for the current day. The date is shown next to the indicator name on the left side of the indicator window. The gap down occurred on 14-November and the OBV indicator is dated 13-November. ​
 +Chartists wishing to see the effects of a big volume bar can use intraday charts. The example below shows OBV moving sharply lower on the 30-minute chart. Notice the small space between OBV and the current price bar; this is due to the fact that OBV will not be shown for the current 30-minute bar until the 30-minute period is over and the bar is complete. ​
