Technical analysis involves the use of a price chart, which provides a roadmap for past price behavior. A technical analyst relies on the past to predict the future.
Charts are useful tools for investors and traders as they offer insight into herd behavior. In a book written in 2004, author James Surowiecki explained how crowds make better decisions than individuals. Markets are embodiments of Surowiecki’s thesis as the current price of an asset is the level where buyers and sellers meet in a transparent environment.
When it comes to the global foreign exchange market, buyers and sellers of currencies determine the rates of one foreign exchange instrument versus others on a real-time basis. At the same time, governments manage the level of currency volatility to maintain stability. Technical analysis can be particularly useful in the currency markets as technical levels can provide clues about levels where government intervention is likely to occur.
Technical analysis includes support and resistance levels where currency pairs tend to find lows and highs. At the same time, price momentum indicators often signal where exchange rates are running out of steam on the up and the downside.
Technical analysis can breakdown at times when black swan events occur.
In the world of foreign exchange, the over-the-counter market is the most liquid and actively traded arena. The OTC market is a global and decentralized venue for all aspects of exchanging the currency of one country for another; it is also the largest market in the world. In April 2019, the average trading volume was $6.6 trillion per day. The OTC market operates twenty-four hours per day, except for weekends.
Futures markets for currency pairs are smaller, but they reflect the price action in the OTC market. When it comes to technical analysis, the futures market provides a window into the price trends and overall state of the strength or weakness of one currency versus another.
The dollar versus the euro currency pair is the most actively traded foreign exchange relationship as both foreign exchange instruments are reserve currencies.
The weekly chart of the dollar versus the euro futures contract displays the price action in the currency pair since late 2017. The bar chart on the bottom reflects the weekly volume, which is the total number of transactions. The line above volume is the open interest or the total number of long and short positions.
When volume and open interest are rising or falling with the price, it tends to be a technical validation of a price trend in a futures market. When the metrics decline with rising or falling prices, it often signals that a trend is running out of steam, and a reversal could be on the horizon. Volume and open interest are two technical metrics that aid technical traders looking for signs that a trend will continue or change.
Stochastics and relative strength indices can provide a window into the overall power of a trend in a futures market.
Beneath the weekly price chart, the slow stochastic is an oscillator that aims to quantify the momentum of a price rise or decline. Stochastics work by comparing closing prices with price ranges over time. The theory behind this technical tool is that prices tend to close near the highs in rising markets and near the lows in falling markets.
A reading below 20 indicates an oversold condition, while over 80 is a sign of an overbought condition. On the weekly chart of the euro versus the dollar currency pair, the reading of 31.42 indicated that the stochastic oscillator is falling towards oversold territory in a sign that the downtrend could be running out of steam.
The relative strength indicator compares recent gains and losses to establish a basis or the strength of a price trend. A reading below 30 is the sign of an oversold condition, while an overbought condition occurs with a reading above the 70 level. At 45.55 on the weekly dollar versus euro chart, the indicator points to a neutral condition in the currency pair.
Technical analysts look for areas of price support and resistance on charts. Support is a price on the downside where a market tends to find buying that prevents the price from falling further. Resistance is just the opposite, as it is the price on the upside where a market tends to experience selling that prevents it from rising further. When a price moves below support or above resistance, it often signals a reversal in a bullish or bearish price trend.
Technical analysis is not perfect, as the past is not always an ideal indicator of the future.
The chart of the currency relationship between the US and Australian dollar shows that the price broke down below technical support and experienced a spike to the downside. The price movement turned out to be a “blow-off” low on the downside that reversed after reaching a significantly lower price.
Technical analysis provides a roadmap of the past in the quest for insight into the future. Many market participants use technical analysis to make trading and investing decisions, which often creates a self-fulfilling prophecy as a herd of transactional activity can create or impede a price trend. Technical analysis is a tool that foreign exchange traders use to project the path of least resistance of exchange rates.
Some of the most influential participants in the foreign exchange markets are governments. Historical price volatility in foreign exchange markets tends to be lower than in most other asset classes because governments work independently or together, at times, to provide stability for exchange rates. Therefore support and resistance levels tend to work well over time.
