Dow Theory Theory that traders must know: From the past to practice

When it comes to technical analysis, many people may not know where market predictions originate. In fact, Dow Theory which was developed over a century ago, remains one of the most effective tools for those who want to understand market movements.

What is Dow Theory and Where Did It Come From?

In the early 20th century, Charles H. Dow and William Peter Hamilton developed a concept viewing the market as a dynamic system, not just a collection of random numbers. They believed that price movements reflect all available information in the market, leading to the Dow Theory, which forms the foundation of technical analysis.

This theory does not only discuss price charts but also encompasses market behavior, investor psychology, and identifiable trend characteristics.

6 Key Principles of Dow Theory

1. The market discounts all information
Whether it’s news, earnings forecasts, or fundamental factors, all are reflected in the price already.

2. There are 3 levels of trends simultaneously
Each asset, from major to minor, moves in nested (nested trends).

3. Volume must confirm price movements
If prices rise but volume decreases, or prices fall but volume remains quiet, it signals that the trend may not be strong.

4. Different indices must confirm each other
If the main market is bullish, supporting signals should appear across multiple indicators simultaneously.

5. Every trend has 3 phases
Accumulation, the major upward movement, and distribution.

6. Trends continue until clear reversal signals appear
A change in direction requires solid evidence, such as Lower Highs or Lower Lows in an uptrend.

The Structure of the 3 Levels of Trends

Primary Trend (Main trend)
Duration of 1 year or more, sometimes up to 4 years, representing the overall market direction.

Intermediate Trend (Secondary trend)
Lasts between 3 weeks and 3 months, reflecting adjustments within the primary trend.

Minor Trend (Minor trend)
Short-term movements not exceeding 3 weeks, small fluctuations on the chart.

Each level shows similar characteristics: Uptrend (Bullish), Downtrend (Bearish), or Sideways (Horizontal), with clear distinctions.

How to Identify the Direction: Higher High vs Lower Low

In an Uptrend

• Make new higher highs (Higher High)
• Raise lows higher (Higher Low)
• Looks like an expanding “W”

In a Downtrend

• Make new lower highs (Lower High)
• Lower lows (Lower Low)
• Looks like a collapsing “M”

In a Sideways Market
Prices fluctuate without clear higher highs or lower lows, like a range-bound market.

Double Bottom and Double Top: Trend Reversal Signals

Double Bottom (Double Bottom)
Occurs when the price hits a low, then rises, and hits the same low again with low volume. This signals the end of a downtrend and a potential shift to an uptrend.

Double Top (Double Top)
Conversely, when the price reaches a high, then drops, and hits the same high again, it may indicate a reversal to a downtrend.

Strengths of Dow Theory for Traders to Know

✓ Stable foundational system - Clear principles that are easy to understand and apply.

✓ Effective in identifying market direction - Helps traders plan their trades better.

✓ Indicates trend strength - Volume analysis confirms whether the trend is reliable.

✓ Not dependent on economic data - Can be used in uncertain market conditions.

Limitations to Be Aware Of

✗ Confirmation delay - Sometimes, by the time a signal is confirmed, the price has already moved far.

✗ Does not include fundamental factors - Important news from companies or economics may not be immediately reflected in prices.

✗ Requires multiple confirmations - Without clear signals, traders might enter trades in the wrong direction.

Applying Dow Theory to CFD Trading

Once you study Dow Theory, you can apply it to CFD trading because these products allow trading both bullish and bearish positions.

Example planning:

• Analyze gold charts showing a clear Uptrend with Higher Highs and Higher Lows
• Plan a bullish trade, choose a Buy order
• Set appropriate Lot Size and leverage according to your risk tolerance
• Place well-defined Take Profit and Stop Loss levels

Using Dow Theory helps traders develop a clear plan, understand where the market is, and predict its movement with higher confidence.
