Is it possible to decide if an indicator is trending up or down?

I want to screen a number of stocks, in order to find stocks where my indicator is trending either up or down and if it is above or below zero on the indicators scale. The indicator is an oscillator.


I'm kind of newbie, mind you... :)

Which indicator?

Some indicators plot between 0 and 100 , some scale between 100 and -100.Some are binary which plot 1 or -1.

You have to determine whether your indicator is rising or falling, is it in ovebought or oversold areas?

The indicator is a line that plots between 100 and -100.
0 being the mid point.

I just want to determine if it is rising or falling, and if it is above or below zero, in other words the mid point.

I then want to screen stocks and get a list with stocks that have the following criteria:
Indicator is rising, and indicator is above 0


The indicator looks something like this (but in this example the scale in not between 100 and -100):

IND:=
(Mov((Mov(C,100,S) - Ref(Mov(C,100,S),-15)- LLV(Mov(C,100,S) - Ref(Mov(C,100,S),-15),14))/(HHV(Mov(C,100,S) - Ref(Mov(C,100,S),-15),14)-(LLV(Mov(C,100,S) - Ref(Mov(C,100,S),-15),14))),14,E)*100);

IND;

elit....

To start with, personally I would prefer to read the code as:

Code:

prd1:=100;
prd2:=15;

x:=Mov(C,prd1,S);
y:=Ref(x,-prd2);
z:=x-y;

num:=z-LLV(z,prd2);
den:=HHV(z,prd2)-LLV(z,prd2);

ind:=100*Mov(num/den,prd2,E);
ind;


which has been only slightly modified, but is much easier to read and (to me) makes more logical sense than previous.

To find whether the most recent 'direction' is up or down, use the ROC() function, and to test whether your (-100 to 100) oscilaltor is above or below zero, then just test for values above or below zero.

Please don't post example codes that you never intend using, post the "real code".

Too often the good people here try to offer solutions for "examples" that just "don't work" when applied to the "real code". If we cannot see the real code, how can we provide a solution? If you have the found the Holy Grail and you use the code/information provided to you from the free and open forum then the Grail does not truly belong to you, does it?

Thanks for your replies!

The reason I didn't want to post my indicator (which i hope is in fact the "holy grail") is that I think it is copyrighted.


I want to learn to program metastock myself, and hope I will find time to do this. As I have studied some computer science as a minor subject I have some programming experience, but up until now I have always felt that programming was boring and didn't like it. But now as I have gotten interested in trading I have found an interest in programming.




Anyways, I'll look into the ROC() function. I hope I can get help on this forum when i get stuck. I just got metastock so I have a lot to learn. I just wanted to find out if it was even possible to do the things I want to do in metastock.

Thanks again!
