Classic Chart Indicators
Find descriptions, formulas, parameters, and other help for the indicators and studies used by the Barchart.com Classic Charting application below.
Note: Classic Charts and Technical Charts each have their own set of studies. Classic Charts contain 40 studies, with 6 additional bar types, while Technical Charts contain 46 studies and the ability to add a horizontal trend line. When you switch the Chart Style, any studies you've already applied are cleared as the indicators do not transfer.
View Technical Chart Indicators
When charting any of the studies, the argument coloring is red, green then blue. For example, on a Moving Average chart [9, 18, 40], the 9 day would be the red line, 18 day would be the green line and the 40 day would be the blue line. The argument order is displayed on the chart next to the study name.
Detrend Price Oscillator
The Detrended Price Oscillator is a technical indicator that smoothes the trend in prices. When price is detrended using the detrended price oscillator, many technicians believe that cycles and overbought and oversold levels can be more easily identified. The principal is similar to using longer length technical indicators rather than shorter length technical indicators. It removes some of the 'noise'.
To calculate the detrended price oscillator an x-period moving average is centered. This is done by shifting the moving average back [(x/2) + 1] period. This centered moving average is then subtracted from the close. Because it is set up as an oscillator, it will cross above and below zero. The last [(x/2) + 1] period will have no value. This is because the detrended price oscillator is shifted back [(x/2) + 1] period. The detrended price oscillator may recognize underlying cyclical movements in price.
