A trader must identify where they are on this hierarchy. Here lies the greatest challenge: You can count five waves up on a 1-minute chart while the daily chart is showing a three-wave correction. The key is to establish a “preferred” count and an “alternate” count.

: Wave 3 cannot be the shortest of the three motive waves (1, 3, and 5).

The Elliott Wave Theory is a sophisticated method of technical analysis that identifies recurring price patterns related to changes in investor sentiment. Developed by Ralph Nelson Elliott in the 1930s, the theory posits that market movements are not random but follow a natural sequence of cycles driven by crowd psychology—shifting between optimism and pessimism. The Core Structure: 5-Wave and 3-Wave Patterns

Theory is useless without execution. Here is a step-by-step strategy for trading a bullish impulse wave.

A five-wave structure (labeled 1, 2, 3, 4, 5) that moves in the direction of the main trend.

While the theory allows for flexibility in wave structure, there are three "hard rules" that can never be broken. If a trader identifies a wave count that violates these rules, their count is incorrect.

Ralph Nelson Elliott (1871–1948) was not a professional trader. He was an accountant who specialized in turn-of-the-century railroad finances. After a severe illness left him bedridden in the 1930s, Elliott needed a mental pursuit. He began analyzing 75 years of stock market data, including hourly, daily, monthly, and yearly charts.

Because human psychology does not change, the patterns repeat. However, they repeat at all time frames—a concept known as . A five-year bull market has the same wave structure as a five-day rally. As Elliott put it: "Because man is subject to rhythmical procedure, calculations having to do with his activities can be projected far into the future."

Given one chart, five experienced Elliott Wave analysts might produce five different wave counts. Critics argue that because the practitioner decides which wave is which, the theory is not falsifiable. If a prediction fails, the analyst simply “recounts the waves.”
