Hi all,

Can anyone tell me why the FlatLines in this efs is not coloring red?

Thanks

Not sure if these are the flatlines you are referring to but they are colored in red at my end (note that I had to comment out the call to the SchirdingStoch.efs to get the formula to work)

Since you are painting the price bars you should add the following statements in preMain

setColorPriceBars(true);
setDefaultPriceBarColor(Color.black);//or any other color of your choice 

The latter statement ensures that if neither condition is met then the bars get painted in the color of your chosing (else they get painted in white)

Hi Alex,

Once again, thanks for the bail out! I got the formula to work commenting out the call also. But I have a question. I have a use for the SchridingStoch.efs in my script.

Apparently, calling the SchirdingStoch.efs is causing the incorrect coloring of the flatline bars. Since I need this call in my program, I'm wondering if there is a work around.

Also , does this mean by calling an efsExternal , it overides the fuctionality of preMain??

Again , thanking you and other moderators for the quick responses and help you provide us here in our learning process.

Because you are passing a color and thickness parameter to the SchirdingStoch.efs as part of the efsExternal() call and these are used in the main function of that efs (in lines 79-82) to set the default properties of the plot(s) those same parameters are then applied to the plot returned by the calling (ie strategy1_blaus) efs.
There are various solutions available to you. The easiest one is to change the parameters in the efsExternal() call to the SchirdingStoch.efs. To do this replace the following line

SchirdStoch = efsExternal("SchirdingStoch.efs",14,3,3,2,2,Color.blue,Color.red); 

with

SchirdStoch = efsExternal("SchirdingStoch.efs",14,3,3,1,2,Color.red,Color.red); 

Notice that in this example I have changed both the parameter for the thickness and color.
The other solution is to set the defaults for the color and thickness in the calling efs by replacing the following section of code (lines 73-78)

if(bInit == false){
     DS_Stoch = (amLib.amDSStoch(q,r,s));
     DS_Sig = eval(Type)(u,DS_Stoch);
     setShowTitleParameters(eval(Params));
    bInit = true;
    } 

with the following

if(bInit == false){
     DS_Stoch = (amLib.amDSStoch(q,r,s));
     DS_Sig = eval(Type)(u,DS_Stoch);
     setShowTitleParameters(eval(Params));
     setDefaultBarFgColor(Color.red,0);
     setDefaultBarThickness(1,0);
    bInit = true;
    } 

In this case I override the defaults set by the SchirdingStoch.efs by defining new ones in the calling efs.
Either solution should work and will not affect how the SchirdingStoch.efs will behave when used on its own.

Alex,

Thanking you for the concise explanation and work-around for the ext. call function . The program works fine now.

Your help is surely appreciated. A vast knowledge is always gained on your corrective suggestions to the whats and whys of
script writing. We would be lost without you!

Another change you may want to implement in your script to make it more efficient is to intialize the efsExternal() call inside the bInit routine. To do this first declare a new global variable (ie outside of main and preMain) called SchirdStoch and assign to it a value of null eg

var SchirdStoch = null;
 
function main(...){ 

Then move the call to the SchirdingStoch.efs from its current location (line 67) to inside the bInit routine eg

if(bInit == false){
    SchirdStoch = efsExternal("/newdownloads/SchirdingStoch.efs",14,3,3,2,2,Color.blue,Color.red);
    DS_Stoch = (amLib.amDSStoch(q,r,s));
    DS_Sig = eval(Type)(u,DS_Stoch);
    setDefaultBarFgColor(Color.red,0);
    setDefaultBarThickness(1,0);
    setShowTitleParameters(eval(Params));
    bInit = true;
} 

Then to retrieve the values of SchirdStoch series use the .getValue() method ie SchirdStoch.getValue(0) for the value at the current bar, SchirdStoch.getValue(-1) for the value at the prior bar, etc
