I am
not sure if this would work. It seems that it might but would give you a one day
delay on your signal.

This
is not my system, only something I came up with quickly to test the flaw in
System Tester. I normally set my system tests to execute on the following day's
open. According to support this would prevent an entry signal for two days. I
have not tested this.

AMTo: metastock@xxxxxxxxxxxxxSubject: Re: MAJOR FLAW in
SYSTEM TESTERMaybe you can have the system look forward
to set the position to close at the close the day before and open the opposite
trade at the open the next day.For example:<FONT face=arial
color=#008080 size=4>Enter Long: Cross(Mov(C ,3 ,S ), Mov(C ,18 ,S )
)
[on open]Close Long: Ref(Cross(Mov(C ,18 ,S ), Mov(C ,3 ,S )
),+1) [on close]Enter Short: Cross(Mov(C ,18 ,S ), Mov(C
,3 ,S )
)
[on open]Close Short: Ref(Cross(Mov(C ,3 ,S ), Mov(C ,18 ,S )
),+1) [on close]Would this work for your
system???Michael At 02:14 PM 6/29/2001 -0400, you

THERE IS A MAJOR FLAW IN THE SYSTEM TESTER. <FONT
face=arial color=#008080 size=4>If one places a close long and a close short
position and both the close and the entry in the opposite direction are hit
on that day, the position will be closed but THE OPPOSITE POSITION WILL NOT
BE ENTERED. It is even worse if you choose to close on open the following
day. The opposite signal will not be allowed to trigger until the following
day. To test this
I used the following simple system:<FONT face=arial color=#008080
size=4>Enter Long: Cross(Mov(C ,3 ,S ), Mov(C ,18 ,S ) )<FONT
face=arial color=#008080 size=4>Close Long: Cross(Mov(C ,18 ,S ), Mov(C ,3
,S ) )Enter Short:
Cross(Mov(C ,18 ,S ), Mov(C ,3 ,S ) )<FONT face=arial
color=#008080 size=4>Close Short: Cross(Mov(C ,3 ,S ), Mov(C ,18 ,S )
) Because the
Enter Long & Close Short as well as the Enter Short & Close Long are
identical, one would expect to show at every point both a closing of one
position and an opening of the other. This does not
happen! The same
is true for Experts. If both a Close and an Enter are triggered on the same
day, only 1 symbol will be displayed. They are displayed in order from top
down. I suggest
two actions. First, copy the message above and send it to MetaStock Feedback
at: <A
href="mailto:suggestions@xxxxxxxxx";>suggestions@xxxxxxxxx <FONT
face=arial color=#008080 size=4>Second, until this is fixed, test only longs
or shorts by themselves unless you are using a reversal system where you are
not using Close. <FONT face=arial color=#008080

file: The System
Editor Dialog The
System Editor dialog lets you name the system test, store notes regarding
the system, and define the four trading rules.The trading rules use the
formula syntax explained in the MetaStock formula language section (see What
is the MetaStock Formula Language?). This syntax is very similar to
the syntax used to enter formulas in spreadsheets. Each trading rule
may contain up to 1024 characters. If you are unfamiliar with
the MetaStock formula language, you should see What is the MetaStock
Formula Language?. <FONT face=arial color=#008080

states: long, short, or out. <FONT face=arial
color=#008080 size=4>When out, simple interest is earned at the rate
specified in the System Testing Options dialog (see System Testing
Options).You use the four tabs to select which rule to display and
edit.Enter Long.
This rule specifies when the system should buy long. A long position
can only be entered when the system is short or out. When in a long
position, this rule is ignored. <FONT face=arial

should close a long position. When in a short or out position, this
rule is ignored.Enter
Short. This rule specifies when the system should sell short. A
short position can only be entered when the system is long or out.
When in a short position, this rule is ignored.Close Short.
This rule specifies when the system should cover (i.e., close) a short
position. When in a long or out position, this rule is
ignored.
