One of the oldest frameworks in technical analysis, developed by Charles Dow, which identifies market trends through a series of higher highs and higher lows (uptrend) or lower highs and lower lows (downtrend).
Core Principles of Dow Theory
Dow Theory, developed by Charles Dow in the late 1800s, remains foundational to Technical Analysis. Its six core tenets are: the market discounts everything, the market has three trends (primary, secondary, minor), primary trends have three phases (accumulation, public participation, distribution), indices must confirm each other, volume must confirm the trend, and trends persist until a clear reversal signal appears.
Application to Forex Markets
In forex, Dow Theory helps define trend structure. An uptrend in EUR/USD consists of successive higher highs and higher lows. The trend remains intact until a lower low forms, breaking the sequence. Primary trends last months to years, secondary trends (corrections) last weeks to months, and minor trends last days. This hierarchy aligns naturally with Multiple Time Frame Analysis.
Practical Takeaways for Forex Traders
Dow Theory teaches patience. Trade in the direction of the primary trend and use secondary corrections as entry opportunities. The "trend persists until reversal" principle prevents premature exits. Combined with Elliott Wave Theory for wave counting or Fibonacci Retracement for entry levels, Dow Theory provides the structural framework that more specialized tools refine.
