Identifying Waves Is Key 🔑

As you might’ve guessed, the power of Elliott Wave Theory lies in your ability to correctly identify the waves on a price chart.

The better you get at spotting where the market is within a wave cycle, the better decisions you’ll make — whether to go long (buy) or short (sell).

But before you start labeling waves like a pro, there are a few critical rules you must follow…


🚨 The 3 Cardinal Rules of Elliott Wave Theory

These are the non-negotiables. Break them, and your wave count is wrong — simple as that. And a wrong count can be dangerous for your trades.

So, commit these to memory:

  1. Wave 3 can NEVER be the shortest of the three impulse waves (Waves 1, 3, and 5).

  2. Wave 2 can NEVER retrace beyond the start of Wave 1.

  3. Wave 4 can NEVER enter the price territory of Wave 1 (in a standard impulse wave).

💥 Break any of these rules, and your entire wave count falls apart.


⚙️ Elliott Wave Guidelines (These Can Be Broken)

Unlike the cardinal rules, the following are common patterns — but they aren’t set in stone. Think of them as helpful clues, not absolute laws.

  • Wave 5 may not always exceed Wave 3’s high/low. When this happens, it’s called a truncation.

  • Wave 5 often breaks a trendline drawn from the top of Wave 3 and projected from the start of Wave 1. This shows strength at the end of the trend.

  • Wave 3 is usually the longest and strongest wave in the impulse sequence.

  • Waves 2 and 4 often retrace to Fibonacci levels, offering useful zones for entries and exits.


Summary

Before you dive into using Elliott Waves in your trading strategy:

  • Master the 3 cardinal rules to avoid mislabeling.

  • Familiarize yourself with the guidelines to improve your wave identification skills.

  • Remember: even if wave patterns aren’t perfect, practice makes progress.

Up next, we’ll explore how to actually trade using Elliott Waves — including setups, entries, and exits. Let’s go!
