- The purpose of this system is to draw and/or print volume-high-low-
- close charts for any stock. Bonds, commodities, or other securities
- that have high-low-close prices, can also be charted. Short and long-
- term moving average lines can optionally be included on each chart.
-
- Whenever a new stock is added to the system, the user may specify daily
- or weekly updating of price and volume data, and may also specify the
- number (up to 90) of days or weeks of data to be retained for
- that individual stock. A double-sided diskette can hold data for each
- of up to 110 different stocks.
-
- Volume and high, low and closing prices are typed in by the user from
- data published in Barrons (for weekly updating) or the Wall Street
- Journal or other daily paper. Short- and/or long-term moving average
- periods can optionally be specified or changed at will for each
- individual stock. Moving averages can be computed and charted
- temporarily on a "what-if" basis, or stored permanently on diskette.
- The system does not make buy/hold/sell recommendations.
-
- Per-share annual earnings and dividends are maintained to permit
- computation of the price/earnings ratio and yield for each stock. Also,
- high and low estimated 5-year prices can be entered, to permit
- computation of total annual return. This information may be obtained
- from Value Line or another advisory service.
-
- The stock charting system, which contains several programs and asso-
- ciated text files, is menu-driven, allowing the user to easily select
- all options without memorizing commands. All menus have a "Help"
- function; when invoked by pressing the letter "H", the instructions
- applicable to that part of the system will appear on the screen.
-
- The hardware requirements are an IBM Personal Computer with at least
- 64K of memory and two disk drives (programs on A:, data on B:). The
- stock charting system will operate with either the IBM monochrome or
- graphics adapter, or both, but the graphics adapter is required for
- drawing charts. The system has been tested with DOS 1.1 and 2.0, and
- also on the Compaq computer. Stock charts may be printed on an Epson
- FX-80 or equivalent graphics printer. The program modules are written
- in interpreted BASIC with embedded machine-language subroutines.
