I call the green line "hidden" because it is a blend of prices from around the earnings release period and therefore not something obvious to anyone looking at the chart. Many times the level coincides with other levels that are technically interesting, such as gaps or consolidations, but generally it is a level that is hidden from view. As for the "rule" you are referring to, could you explain what you mean? The red arrow is a best case scenario target for the pattern that is set-up. I don't have a firm target in mind for where I will cover, but I will be looking for when AAPL holds well relative to the overall market. For now, with the news of the exact release date of iPhone6 now announced, it seems like a wait and see period. I will be covering before the start of iPhone6 sales as the stock could heat up at that time.
