Hi Gus,
With the MDK you need to return data within a given "start" and "end"
period. You can't start returning values then stop for a few bars then
start again a few bars later unfortunately.
However, if you're not interested in backtesting and only want it on the
most recent set of data where it might be valid that could be done (eg your
indicator is within range in the last 8 bars then plot it, otherwise leave
it invisible). You might be able to do this yourself with standard
Metastock language too using the following construct:
Eg. Let's say your condition is that we want to plot a line at the low
price of the day when when have a moving average cross:
condition:=Cross(Mov(C,8,S),Mov(C,33,S));
day:=Cum(1);
lastcross:=LastValue(ValueWhen(1,condition,day));
negative:=ValueWhen(1,lastcross<day,day);
valuewanted:=ValueWhen(1,lastcross=day,L);
If(day>=lastcross,valuewanted,negative);
What does it mean:
Condition is the moving average crossover.
The day represents the bar # on the chart, which we use in subsequent
conditions.
Lastcross is the last bar # on the chart that we had a crossover
Negative is an invalid condition for the vast majority of the chart. This
condition is use to allow us to plot a "blank" indicator across the chart.
Valuewanted is the value we want to plot (in this case, the Low on the
crossing day)
The final line tells us to plot the valuewanted only if we are beyond the
start date, and the "negative" value is used to stop the indicator plotting
before the desired date.
A neat little trick for Metastock for sure... Only works when you just want
to see what is happening NOW - not for backtesting at all.
Cheers,
Richard Dale.

Subject: Re: [Metastockusers] Digest Number 1003
Richard or someone else with a developer's kit:
Is there a way using the developer's kit, to clear the value of an indicator
when the price goes away from the level of the indicator. Let me clarify, in
MS if you set an indicator that has direct relation to the price like
certain levels e.g. a formula that draws a line at the H,L,C of yesterday,
if the price is way away from those levels, e.g. it gaps up $2 today, then
the chart is squashed since MS tries to show all data including the
indicator's. I wanted to create a formula that shows the line only when it
is within 10c of the price, this way MS adjust to the price rather than all
the indicator on that pane. In other words, the program would have to reset
the variable and recalculate when the price comes into range.
Is this possible?

Subject: Re: MetaStock Developer's Kit
Thanks Richard,
This is what I expected. I'm surprised that MetaStock developers
have not improved the way parameters are optimized at this late date.
Since the advent of low priced computing, the field of Operations
Research has produced many algorythms to speed up the process of
finding global optimum solutions. Single stepping through all
possible combinations is low tech, at best!

p.s. My remarks refer to experience with MS 7.22.

I use the ICE Program to scan for stocks. I then cut and paste the
symbols from ICE to excel. Is there a way to import the symbol list
from Excel into a Metastock File?

Subject: Re: Import Excel Stock List into Metastock
The list must take one of two forms -
a list of just tickers
AAPL
PEP
MSFT
or a list of in the form company name, ticker
Apple Computer,AAPL
Pepsico,PEP
Microsoft,MSFT
After creating the files you must change the extension to .sym. (from .txt)
The file must be placed in the folder that holds the Downloader (e.g.
C:\Programs/Equis/Downloader)

1. Try updating your Video Graphics drivers.
2. If you have lots of indicators in your default template, try reducing
the number of indicators. Metastock used to have a bug whereby if it tried
to open multiple charts, it would "reduce" the size of the chart window but
if there were too many indicators it would crash.
3. Which version of Metastock are you running? Metastock v7.00 and v7.01
had significant problems with Windows XP.
Cheers,
Richard Dale.

That's a unique problem being faced by you. What I suggest is that you
download all the windows patches and updates. Maybe that should help you.
