Declining volume is often a warning that the trend is near completion. A solid price uptrend should always be accompanied by rising volume. In The Visual Investor, John demonstrates the essential visual elements of technical analysis.

As trading costs have steadily declined in recent decades (e.g., Jones 2002), rules that earn high profits by exploiting a zero-cost system should, all else equal, be more successful during the early subperiods. Another explanation for our results is different levels of market efficiency over time, which is in line with the adaptive market hypothesis of Lo (2004). According to that, the first subperiods can be interpreted as “early evolutionary stages,” which are subject to greater market efficiency in the future, for instance, through gradual learning by market participants. Thus, technical trading strategies can generate superior performance over certain periods, and the more proprietary these strategies are, the longer they may yield attractive results. In addition to that, the research on technical trading rules generally faces the challenge of an accurate statistical analysis, which is necessary to produce reliable results. However, adequately dealing with data snooping is technically challenging, such that statistical tests that address this problem were not developed until after White (2000) introduced a “Reality Check” for data snooping.
Oscillators are widely employed by short-term traders to identify market extremes such as overbought and oversold conditions. Other indicators include On-balance volume, Williams’ Percent R, Alligator, Ichimoku cloud, etc. One of the theories of technical analysis is that the price of an asset tends to trend, and another is that the price has a mean-reversion tendency.

Then, a long signal is triggered when \(RSI_t(n)\) rises above \(50-v\). The relative strength index technical trading rules is a so-called oscillator, which was first introduced and studied by Levy (1967a, 1967b) and Wilder (1978). It defines a ratio of the sum of positive to the sum of all absolute price changes over a prespecified time period.
Data snooping bias and research on technical analysis
- When the conditions are true, a buy or sell order is sent.
- More importantly, the out-of-sample performance is mostly insignificant or negative and significant.

Hamilton, Robert Rhea, Edson Gould, and John Magee further contributed to Dow Theory concepts.
Understanding Technical Analysis
Today, even a small retail trader has access to software and computer power unheard of as recently as the early 2000s. It was not until the 2000s that quants, quantified strategies, and trading made some headway. The rise of computing power made it much more attractive, not to mention all the money that could be made by being successful. Worth noting is the risk-adjusted return, which is the annual return divide by the time spent in the market.
