A flying plateau is a pattern that forms after a stock has made a strong move up. Strong stocks will consolidate gains sometimes in a flat, sideways pattern in a tight range instead of selling back. This is a very bullish pattern, especially if it is formed on low volume. Picture a 45 degree rise and then a move sideways for several sessions. Strong stocks tend to rest in these patterns, and then start another leg up.
