Typeahead retrieval of a moving average, on-balance volume, and a stochastic oscillator

From ticker to a default chart

After a ticker or company name was typed, a stock, index, or exchange-traded fund chart loaded under default settings that could then be changed.

The reviewed web charting workspace listed more than fifty addable studies and continued to add new ones.

Indicator typeahead for three studies

Indicator typeahead is letter-by-letter filtering that shrinks a large study catalog to matching names. Typing the opening letters of a study name narrowed the indicator menu until a moving average could be selected.

The same letter filter placed on-balance volume at the top of the list after its initial letter was entered. On-balance volume is a volume-based chart study retrieved from a searchable indicator list and used as a confirmation signal.

Entering the initial letter associated with stochastics brought that oscillator to the top of the filtered list. A stochastic oscillator is a bounded momentum study surfaced from the same searchable indicator menu as other quantitative models.

Lookback, bar interval, and price scale

A moving average is a lookback average of ordered prices that is plotted after the user sets period and color. Choosing a moving average opened controls for the lookback period and the plot color on the price chart.

Bar interval is the sampling length of each plotted bar, selectable from one-minute through one-year presets. Bar length could be chosen from twenty presets spanning one minute per bar through one year per bar.

Price scale is the vertical mapping of price, switchable between arithmetic and logarithmic. Chart settings allowed candlesticks or four other plot styles, separate up- and down-bar colors, an arithmetic or logarithmic scale, a prior-close reference line, and an optional second security for comparison. That optional second security is a comparison series plotted against the primary symbol.

Editorial drill before a fourth study

Editorial interpretation: the archive records how studies were found and how the pane was configured. It does not rank the three studies or show that any combination forecasts price.

Editorial rule: keep the moving average, on-balance volume, and the stochastic oscillator as the only studies until the chosen lookback, bar interval, and price scale can be stated in plain language. A fourth study waits until those choices are defended.
