Relative Volatility Index (RVI)

Donald Dorsey worked out the Relative Volatility Index (RVI), which is the RSI, only with the standard deviation over the past 10 days used instead of everyday price fluctuations. The RVI is usually used as a fixing indicator, because it measures in other way than price and it has the aim to interpret FOREX market strength. It is usually used at the scale from 0 to 100 to find out the direction of volatility during the RVI's measurements. The volatility is more to the upside, when it is comes over the 50's mark on the scale. The direction of volatility is to the downside, when it falls lower than the 50's level on the scale.

Typical Price

The Typical Price function measures the average of the high, low, and closing prices for the day using a simple, single-line plot. The ordinary price gives a simplified view of the day trading prices for as well as it happens with other price-adjustment functions. You can use it for smoothing out some of the inconstancy of the closing price because it comprises information for the whole trading day and not only the result of the day's end. The Typical Price indicator is measured by adding the high, low and closing prices together, and then dividing by three.

Standard Deviation

Standard Deviation measures volatility statistically. It shows the difference of the values from the average one. The volatility as well as the standard deviation gets higher if the closing prices and average closing prices differ considerably. If the difference is insignificant the standard deviation and the volatility are low.

Williams' Accumulation/Distribution (A/D)

Developed by Larry Williams, the Williams' Accumulation/ Distribution indicator is used to define if the marketplace is controlled by sellers (distribution) or by buyers (accumulation) and trading when there is discrepancy between the A/D indicator and price.

Williams Percent Range (%R)

Williams %R (Williams Percentage Range) is a momentum indicator that helps to highlight overbought and oversold areas in a none-trending market. As seen from its name, it was developed by Larry Williams.

Relative strength index (RSI)

The RSI Indicator is a a good tool to help identify overbought/ oversold conditions, divergences, and crossovers that investors use to identify new trends in a stock or the market. The RSI indicator is plotted on a panel above or below the price chart. It is easy to identify the set-up as the RSI indicator shows the market’s strength compared to the historical price trend. The shorter the time period used for the RSI calculation, the more volatile the RSI’s movements. The typical period is 14, though it can be easily adjusted using stock charting programs. Other values that are used are 9, 11, and 25 periods.
