What is really neat about the Equis approach to bugs 
is that they fix the bug in the next version and then charge you to 
upgrade.   A perpetual motion machine.

  At 
  least one person who is not a fraet to tell the truth. In fact Equis is 
  spending much more time in publishing their own so called Performance Systems 
  and their Data on demand than they are fixing the TONS of bug or 
  flaws.

    There are several flaws in the system 
    tester.This has been discussed here, but Equis wont/can't correct the 
    problems.

      <SPAN 
      class=200402316-29062001>I called MetaStock support today because I was 
      curious about some odd results with the System Tester (ST). I then tested 
      it myself to verify it. THERE  IS A MAJOR FLAW IN THE SYSTEM 
      TESTER.
      <SPAN 
      class=200402316-29062001> 
      <SPAN 
      class=200402316-29062001>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.
      <SPAN 
      class=200402316-29062001> 
      <SPAN 
      class=200402316-29062001>To test this I used the following simple 
      system:
      <SPAN 
      class=200402316-29062001>Enter Long: Cross(Mov(C ,3 ,S ), Mov(C ,18 ,S ) 
      )
      <SPAN 
      class=200402316-29062001>Close Long: Cross(Mov(C ,18 ,S ), Mov(C ,3 ,S ) 
      )
      <SPAN 
      class=200402316-29062001>Enter Short: Cross(Mov(C ,18 ,S ), Mov(C ,3 ,S ) 
      )
      <SPAN 
      class=200402316-29062001>Close Short: Cross(Mov(C ,3 ,S ), Mov(C ,18 ,S ) 
      )
      <SPAN 
      class=200402316-29062001> 
      <SPAN 
      class=200402316-29062001>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!

      <SPAN 
      class=200402316-29062001>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.

      <SPAN 
      class=200402316-29062001>I suggest two actions. First, copy the message

      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?.
       
      Remember that a trading system 
      can be in one of three different states:  long, short, or 
      out.
       
      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.
       
      Close Long.  This rule 
      specifies when the system should close a long position.  When in a 
      short or out position, this rule is ignored.<FONT face=Arial 
      color=#008080 size=4>
      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.
