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.
