The Technical Analysis page contains the results of 12 common technical analytics over different periods of time. The analytics used are:
- TheÂ Moving AverageÂ is the average price of the security or contact for the Period shown.Â For example, a 9-period moving average is the average of the closing prices for the past 9 periods, including the current period. For intraday data the current price is used in place of the closing price.
The moving average is used to observe price changes. The effect of the moving average is to smooth the price movement so that the longer-term trend becomes less volatile and therefore more obvious. When the price rises above the moving average, it indicates that investors are becoming bullish on the commodity. When the price falls below, it indicates a bearish commodity. As well, when a moving average crosses below a longer-term moving average, the study indicates a down turn in the market. When a short-term moving average crosses above a longer term moving average, this indicates an upswing in the market. The longer the period of the moving average, the smoother the price movement is. Longer moving averages are used to isolate long-term trends.
- TheÂ Price ChangeÂ and associatedÂ Percent ChangeÂ is the difference between the current Last Price, and the Last Price from the Period shown.
- ForÂ Commodities, theÂ Average VolumeÂ figure is the average for the individual contract over the specified period of time.
Average True Range
- The stochastic values simply represent the position of the market on a percentage basis versus its range over the previous n-period sessions. The percentage scale runs from zero to 100%. The Stochastic Indicator shows where a securitys price closed in relation to its price range over the specified time period. There are three primary stochastic values:
- Raw StochasticÂ - the most basic value representing the stochastic value for each period. This is also referred to as raw K.
- %KÂ - the first smoothing of the raw stochastic, usually with a 3-period exponential moving average.
- %DÂ - the smoothing of the %k value, usually with another 3-period exponential moving average. Also known as slow K.
- High Average True Range values often occur at market bottoms following a panic sell-off. Low Average True Range values are often found during extended sideways periods, such as those found at tops and after consolidation periods. The True Range indicator is the greatest of the following:
- The price difference from todays high to todays low.
- The price difference from yesterdays close to todays high.
- The price difference from yesterdays close to todays low.
(MACD Oscillator is calculated against the 3-Day Moving Average)
- The Relative Strength Index (RSI) is one of the most popular overbought/oversold (OB/OS) indicators. The RSI is basically an internal strength index which is adjusted on a daily basis by the amount by which the market rose or fell. It is most commonly used to show when a market has topped or bottomed. A high RSI occurs when the market has been rallying sharply and a low RSI occurs when the market has been selling off sharply. The RSI is expressed as a percentage, and ranges from zero to 100%.
- Williams Percent R was developed by Larry Williams. It indicates overbought/oversold market conditions, and is expressed as a percentage, ranging from zero to 100%. Percent R is the inverse of the Raw Stochastic.
- Historic volatility is the standard deviation of the price returns over a given number of sessions, multiplied by a factor (260 days) to produce an annualized volatility level. A price return is the natural logarithm of the percentage price changes or ln[Pt/P(t-1)]. A volatile market therefore has a larger standard deviation and thus a higher historical volatility value. Conversely, a market with small fluctuations has a small standard deviation and a low historical volatility value. Historical volatility is available on a daily chart, and on the Technicals Summary page for an individual ticker symbol/commodity contract. Historical volatility can also be used as a tool by traders who are trading only the underlying instrument. Quantifying the volatility in a market can affect a traders perception of how far the market can move and thus provides some help in making price projections and placing orders. High volatility may indicate a trend reversal as heavy buying/selling comes into the market and may sharp price reversals.
- The MACD Oscillator is the difference between a short-term and a long-term moving averages. When the MACD Oscillator is above the zero line, conventional wisdom interprets this as a bullish signal, and conversely, when the histogram is below the zero line this is interpreted as a bearish signal. The red line being above the green line reinforces a bullish signal, and the red line below the green line reinforces a bearish signal. Other interpretations use crossovers between the red and green lines as market timing signals if the resulting direction of both lines is the same. Going up is bullish, going down is bearish.
