There is a price reversal pattern called an "island reversal," and we see one on the chart of TripAdvisor (TRIP).
An island reversal needs a few ingredients, and they appear in the chart, above. Prices make a gap up in October. They trade sideways in a relatively narrow range. And then the island is completed with a gap to the downside, which happened this morning. The price action of the narrow sideways range is not connected to the rest of the price action, and thus the idea of calling this an island.
Where does TRIP travel from here? Probably lower, but we will wait and see how this develops.
