On the Volume Alert Trigger page list GTN is registering a preliminary buy alert. This is not something that I want to chase.

Here is a chart showing the volume surge, a very good surge.

Here is a chart showing price relative to a 2.3% envelope around the 5 day moving average. You can see that the price is well outside of the envelope suggesting that this opportunity is too extended to chase. You would have to have placed a buy order within the first 15 minutes of trading to have caught this properly. At that time the volume trigger alert would have been indeterminate.
