"Ichimoku" indicator

[Jiro Kato <paruparo@xxxxxxxxxxxxxxxxx>]

Steve and Harley,
Thank you for your messages.  I could write "ichimoku" indicator.
"Ichimoku" has five lines and because color-line property of each line 
should be different, I could not handle it as one indicator.
If you want to try it, you'll make five indicator, with the following
property, for example.

1 base_upper:(red)
   (HHV(HIGH , 9) + LLV(LOW , 9)) /2;
2 base_bottom:(red, break line)
  (HHV(HIGH , 26) + LLV(LOW , 26)) /2;
3 futurespan_upper:(darkgreen)
  Ref(((HHV(HIGH ,52 )/2+LLV(LOW, 52)/2)),-26);
4 futurespan_bottom:(darkgreen, break line)
  Ref(((HHV(HIGH ,52 )/2+LLV(LOW, 52)/2)),-26);
5 previous_span:(magenta)
  Ref(CLOSE , 26) ;

You can compare this indicator with a genuine "ichimoku" chart on the
web, for example,
http://plaza4.mbn.or.jp/~skoike/top_eng.htm

Questions again:-
1 You will see on the web plotting for some 26 future days is needed,
  but I don't know how to do it with MetaStock.
2 Another thing I want to do is to draw lines between futurespan_upper
  point to futurespan_bottom point. How can I do it by MetaStock?

Remark:- 
  Next target will be "three legs chart", another popular chart for
Japanese.
