If I were you I would google GOIG and use the "latest" or "past 24 hour" filter. If you see a lot of pages pop up, especially new business articles, you should be concerned about a flood of new buyers and look to get in as soon as you can. If you think that the action might cool off after an hour or two, wait for the subsequent sell-off that would follow such a pause and look for bid support to reform around a new lower support (if you have access to L2).
