Indicators that study price movement with the goal of showing when an instrument is overbought or oversold.
In his article "The Quest For Reliable Crossovers" (Stocks and Commodities Magazine, May 2008) author Sylvain Vervoort explains a trading method using the crosses of two moving averages: a zero-lag triple exponential moving average of the typical price HLC/3 and the Heiken-Ashi Close. The Vervoort Oscillator plots the difference between these averages. Vervoort recommended a 55 period average (1 period look back) on daily charts.
ToTheTick.com Power Zones is the Investor/RT implementation of the daily Power Zones offered by ToTheTick.com. This indicator is implemented via the External Data indicator which is specailly programmed for ToTheTick.com to dynamically grab the zone data from the ToTheTick.com servers. Users must obtain credentials from ToTheTick.com which are entered into the Power Zones preferences in order to activate the indicator.
Polynomial Regression Channel (PRC) is an RTX Extension indicator that draws a best fit n-degree polynomial regression line through a recent period of data. Setup parameters for the indicator include the degree of the polynomial (1 - 6) and number of bars to analyze. Bands are drawn above and below the regression line between two user-specified multiples of standard deviation. The bands self adjust for volatility.
The Investor/RT Math Lines Indicator is the Linn Software implementation of the popular Murrey Math Lines. The Math Lines indicator produces a series of equidistant price-based support and resistance levels. Each level is labeled from 1/8 thru 8/8. The 8/8 (or 0/8) lines are considered the most difficult to break. 1/8 and 7/8 lines are considered weak support and resistance. 2/8 and 6/8 lines are considered strong reverse points. 3/8 and 5/8 are considered areas where it is very likely that the price will either pierce this range fast or will remain inside it for a long time.
The Williams %Range (%R) Study, is the exact inverse of Lane's Stochastic Study. You may see the relationship between the stochastic and %R very clearly by charting the same symbol in two chart windows that are stacked vertically. Put the %R in one window and stochastics in the other as shown.
Stochastic is a momentum or price velocity indicator developed by George C. Lane.
This indicator was developed based the January 2002 Stocks and Commodities article entitled Relative Vigor Index. This indicator is an oscillator built on the basic equation (CL - OP) / (HI - LO). The oscillator is basically in phase with the cyclic component of the market prices.
The Relative Strength Index (RSI) is a popular price momentum oscillator developed by J. Welles Wilder and introduced in his 1978 book New Concepts in Technical Trading Systems. The RSI oscillates in a range between 0 and 100 representing a comparison of the magnitude of a stock's recent gains to the magnitude of its recent losses.
In mathematical terms, RSI = 100 - 100/(1+RS) where RS is calculated as the ratio of two exponentially smoothed moving averages, AG/AL. AG is the average price gain over some period and AL is the average price drop over some the same period.
Rate of change is a price momentum indicator. It is a simple calculation of the current price divided by the price some number of periods ago. For example, if the current price is 50 and the price 30 days ago was 40, then the 30-day rate of change is 50/40 or 1.25. The result is multiplied 100 and the resulting line oscillates around the 100 reference line. An optional smoothing moving average may be applied to the raw rate of change. Either or both raw and smoothed lines may be draw in the chart window. Rate of Change is part of the Investor/RT scan language also.
The Random Walk indicator is used to determine if an issue is trending or in a random trading range. It attempts to do this by first determining an issue's trading range. The next step is to calculate a series of RWI indexes for the maximum look-back period. The largest index move in relation to a random walk is used as today's index. An issue is trending higher if the RWI of highs is greater than 1, while a downtrend is indicated if the RWI of lows is greater than 1.
