Sat,
The code that I gave you had some errors in it but was posted to give
some ideas.
Your original question was..."how to restricted display with
specified priode of future date instead of back time priode."
Then your logic says:
"1. check a month ,if month below 12(december) ,then check the year"
"2. check the year ,if the year below 2008 ,then run the indicator"
The logic behind a restricted display is to simply display an
indicator during a specific period of time. The indicator is
calculated during the complete period of available data. It is
displayed only when the appropriate period/s of time are available.
This is not something you would use to trade from.
Let's look at your logic:
checkmonth:=If(Month()>12),-1),1,0));
checkyear:=If(year()>2008),-1),1,0));
run the indicator if value 1, else delete/hide/stop calc the
indicator when value 0
Let's Rewrite this to:
{zero value version}
checkmonth:=If(Month()<=12,1,0);
checkyear:=If(Year()>2004,1,0);
If(checkmonth + checkyear = 2,MACD(),0);
or we could write this:
{NA value version}
checkmonth:=If(Month()<=12,1,0);
checkyear:=If(Year()>2004,1,0);
X:=checkmonth + Checkyear =2;
ValueWhen(1,x,MACD());
The first formula gives a zero value until it can calculate. The
second gives a NA...meaning not enough information to calculate.
There may also be a difference in the display and that is due to
delay by the valuewhen(first,...,...).
Also notice that the checkmonth argument is changed to Month()<=12.
The explanation is that there are only 12 months to a year. So we
could only have 12 or less.
You will need to change the date to whatever is appropriate for your
use. I used 2004 so that I could see the display.
Can we get metastock to "show this messegge("This Indicator run error
priode of this month")? You could if you are using the formula in an
expert but not as a drop down indicator.
Finally, I am curious as to what your intended use will be for this
indicator?
Hope this helps,
Preston
