Automatic Elliott Wave count: how to read it and what invalidates it

Elliott Wave counting is slow and subjective by hand: two analysts look at the same chart and see two different counts. An automatic count does the bookkeeping for you. It does not remove the uncertainty; it makes it visible. This guide explains how such a count is built, which rules it must respect, and how to use it without fooling yourself.

How an automatic count is built

• Turning points on several scales. The chart is reduced to swings (a zigzag) at several sizes, from small to large moves.
• Candidate counts. Impulses (1-2-3-4-5) and corrections (A-B-C), alone or in sequence, are fitted to those swings. Any candidate that breaks a rule is thrown away.
• Ranking by guidelines. The survivors are ranked by how well they fit typical Fibonacci ratios, alternation between waves 2 and 4, and how much of the chart they explain. The best becomes the primary count; up to three clearly different alternatives are kept.

The three rules that are never broken

• Wave 2 never goes beyond the start of wave 1.
• Wave 3 is never the shortest of waves 1, 3 and 5.
• Wave 4 does not enter the price territory of wave 1 in a regular impulse. If it does, the pattern can only be a diagonal.

Everything else (Fibonacci ratios, alternation, channels) is a guideline. Guidelines rank counts; rules eliminate them.

The number that matters: the invalidation price

Every count implies a next move, a target zone and a price that proves it wrong. For example, after a completed five-wave impulse the next move is usually a correction into the 38.2–61.8% retracement zone of the whole impulse, and the count is invalid if price goes beyond the end of wave 5. Targets are guesses; the invalidation price is a fact you can act on. It tells you exactly where your idea has failed.

A four-step routine

1. Look at the primary count and the alternatives. If they disagree on direction, the chart is unclear, and that is information too.
2. Write down the invalidation price.
3. Set an alert there.
4. Decide in advance what you will do if it is hit, before the market decides for you.

In PrimeScope

Elliott Waves (auto) draws the primary count with up to three alternatives, the target zone of the next wave and the invalidation price, on any chart from M15 to D1. The Wave Scanner runs the same count over your whole watchlist and ranks the setups by reward-to-risk. Both are computed on the server on closed candles.
