DESCRIPTION OF DATA ENTRY SCREEN (1 of 6)
The data entry screen can display the volume and prices for up to 13 trading
periods (days or weeks) at a time. A selector block is visible on the screen,
in the form of a solid bar which covers a single data item. A trading period
is selected (for making changes, etc.) when the selector block is on the same
line as the date of that period. The selector block can be moved through all
of the trading periods, and also to the volume or high, low or closing prices,
by means of the cursor keys on the right side of the keyboard.
The up-arrow key moves the selector block up one line each time it is pressed.
If necessary, the display will scroll one line towards the earliest (least
current) volume and price data.
The down-arrow key moves the selector block down one line each time it is
pressed. If necessary, the display will scroll one line towards the latest
(most current) volume and price data.
The left- and right-arrow keys move the selector block horizontally to the
volume or high, low or closing price. It cannot be moved to any of the other
data items.
DESCRIPTION OF DATA ENTRY SCREEN (2 OF 6)
The PgUp key moves the display 10 lines up towards the earliest price data.
There is an overlap of 3 lines. The selector block is placed on the top line.
The PgDn key moves the display 10 lines down towards the latest price data.
There is an overlap of 3 lines. The selector block is placed on the bottom
line.
The Home key moves the display to the earliest price data and places the select
pointer on the least current trading period.
The End key moves the display to the latest price data and places the select
pointer on the most current trading period.
The other functions are invoked by typing the corresponding letter keys.
These other functions are described in the next screens.
DESCRIPTION OF DATA ENTRY SCREEN (3 OF 6)
A = ADD a new trading period date after the latest existing date, and then
enter volume and prices for this new date. The new trading period date
will replace the earliest previously existing date. The new date is com-
puted by the program. If data for this stock is being updated weekly,
the trading period date will always fall on a Friday. If data is being
updated daily, the program will ask if the new date is a holiday. Week-
end days are automatically skipped.
The ADD function works the same way regardless of where the selector block
is at the time the "A" key is typed. After the data has been entered, the
screen will show the most current volume and price data, along with newly
updated moving averages, P/E ratio, yield and annualized potential return.
The ADD (or any other) function can be cancelled before completion by
pressing the Esc key.
C = CHANGE the selected data item only. This function is normally used for
making corrections. Only volume or high, low or closing price can be
changed. Other data items are computed by the program.
DESCRIPTION OF DATA ENTRY SCREEN (4 OF 6)
E = ENTER volume and prices for the selected existing trading period. This
function is used mainly for initial data entry for a new stock that has
just been added to the system, or it can also be used to correct errors.
If data has been updated daily, the program will ask if the selected date
is a holiday. After any change is made to a closing price, all moving
averages are automatically re-computed and re-displayed.
Fractional entry of prices is permitted; a space must be left between the
whole number and the fraction. For examples: 2 11/32; 98 3/16.
If you press the Esc key before all of the data has been entered for the
selected trading date, the Enter function will be cancelled and all of
the original values for that trading date will be restored.
D = apply a stock DIVIDEND or a stock split to all trading periods BEFORE the
selected trading period. The program assumes that post-split data has
already been entered for the selected trading period. This function will
automatically adjust volume, prices and moving averages. Adjustment of
earnings, dividends, price goals and stop limit is optional, in case the
correct values have already been entered.
DESCRIPTION OF DATA ENTRY SCREEN (5 OF 6)
M = change either or both of the MOVING average periods. This function will
automatically perform all necessary computations. A moving average per-
iod cannot be greater than the total number of days or weeks for which
volume and price data are being kept for this stock. If a moving average
is not wanted, specify zero. If only one moving average is wanted, it is
better to specify it as the long-term average because it will be shown as
a solid line on the bar graph.
The program will ask if you want the moving average computations to be
temporary or permanent. If permanent, the moving averages will be saved
to disk and will replace the previous computations. If not permanent, the
just-performed moving average computations will be lost when you SELECT
another stock or QUIT the stock charting system and exit to DOS.
In either case, you can freely switch between data entry and bar graph
displays to observe the effects of changing the moving average periods.
S = SELECT another stock. This will take you back to the stock select screen.
You must go back to the stock select screen first if you want to add or
delete a stock.
DESCRIPTION OF DATA ENTRY SCREEN (6 OF 6)
G = draw a bar GRAPH for the selected stock. If you are using an IBM computer,
it must have a color graphics adapter card installed. Many "compatible"
computers such as the Compaq can already do graphics without a separate
adapter. In either case, either a monochrome or color monitor may be used;
the stock charting system is designed for use with a monochrome monitor.
The Corona is an exception; it requires an IBM-compatible color graphics
adapter in order to properly display the bar chart over the whole screen.
P = PRINT volume and price history in tabular format on the printer. Data for
all trading periods is shown, for the selected stock only, in a format
similar to the screen format. The report is 80 columns wide and pagination
is automatic. It contains no graphics or special characters and so should
work with almost any printer (there is a separate graphics print function
from the bar graph screen).
H = HELP. Displays the explanatory information you are looking at now.
Q = QUIT this program and exit to DOS, so you can run a different program
system, make a backup copy of a disk, etc.
