Hi, I'm using the EKTA 600+- indicator in an expert advisor user formula. This indicator plots two lines representing the standard deviation from both sides of the values moving average for a specific period. Each line has each different value. Unfortunately, I can refer to only one of these values by using the EKTA600 indicator name itself. No any variable is available to refer to each value separately. However, the Data Window of Metastock, shows the two values respectively, as shown bellow at the http://briefcases.pathfinder.gr/download/622311, but with no any label in the front of the second value. Any idea on how to solve this problem ?

in the help section of metastock

Referencing Variables within Custom Indicators

---

Since custom indicators can contain variables, you can reference a specific variable within a custom indicator rather than the entire custom indicator. The fmlvar() function is used to do this.

For example, if the custom indicator named "MyMACD" contains a variable named "SignalLine," and you only want to reference the SignalLine variable, it could be done as follows using the fmlvar() function:

fmlvar("MyMACD", "SignalLine" )

If the variable does not exist within the custom indicator, you will receive an error message.

Just a reminder though, If the base indicator has inputs in it's formula and you then use the fml or fmlvar functions in another indicator,expert,or exploration, the base indicator will then default to the default values

here is an example {My indicator}

pds1:=Input("fast ma",5,100,5);
pds2:=Input("slow ma",10,200,21);
pds3:=Input("signal len",2,100,5);

A:=Mov((H+L)/2,pds1,E)-Mov((H+L)/2,pds2,E);
Sig:=Mov(A,pds3,E);
BullRise:=If(A>0 AND A>Ref(A,-1),A,0);
BullFall:=If(A>0 AND A<Ref(A,-1),A,0);
BearRise:=If(A<0 AND A>Ref(A,-1),A,0);
BearFall:=If(A<0 AND A<Ref(A,-1),A,0);

UZ:=Ref(HHV(Sig,52),-1)*.90;
LZ:=Ref(LLV(Sig,52),-1)*.90;

UZ;LZ;Sig;BullRise;Bullfall;BearFall;BearRise;

If I were to use the Fml() function the last variable named would be the value called

so in the above indicator the fml("my indicator") function would return "BearRise" value based on the default values from the inputs IE: 5,21,5 because BearRise is the last named Variable

If the last line of code was UZ;LZ;Sig;BullRise;Bullfall;BearFall;BearRise;0; The Fml() function would return a 0 value

If I were to use the FmlVar("My indicator","BearFall") function the variable named BearFall would be the value called

so in the above indicator the FmlVar("My indicator","BearFall") would return "BearRise" value based on the default values from the inputs IE: 5,21,5

Where does the indicator come from?

In order to have a clearer view of the above mentioned indicators and my problem too, please: - Go to the http://briefcases.pathfi...file/gozilla/7577/622313 - Click on the Ekta600.rar to download file. This file contains the “2 EKTA 600 + - 30” indicator and the appropriate template for it. - Import the indicator to Metastock. - Copy the template file into Charts folder of Metastock. - Try this indicator to any security, by applying to it the corresponding template. - Then try to use the same indicator in a custom formula (e.g. in Expert advisor). You will see that you can have only the value of the bottom curve. Thank you very much for your attention. P.S. EKTA indicators, were developed by the Greek Community of Technical Analysis, some years ago. Any attempting to find out more details was failed.

Unfortunately Henry, this wonderful workaround only works if the code authors actually use variables when creating their work, e.g.


In this example, in the paste functions window we'd be able to see the result of the indicator, callable with Fml() and also the two variables it contains, callable with FmlVar().

In George's case: the code writers have not used variables e.g.

so the paste functions dialogue box will only show the indicator name, meaning the only value which can be called is using the Fml() which will return the last value i.e. expression 2.

This issues is a good example to all authors of how NOT to write user-friendly codes! It seems the 'Greek Community of Technical Analysis' need to spend some time with MS User Manual and the Formula Primer to improve their coding skills! [:D]
