can't get background color to work

[coolmoss]

I'm a complete coding idiot. Can someone tell me why the setbgcolor statement in the main function won't color my chart properly? Thanks in advance.

Replace the following line
if (vCCI14_of_HLC3 >= 10 ) {
with
if (vCCI14_of_HLC3.getValue(CCIStudy.CCI) >= 10 ) {

Alexis,

Thank you much. As I"m trying to understand and learn how to code better, can you explain how a person figures out what you told me. I"ve read the javascript manuals online and several books and the esignal info. None of it that I can recall or find mentions this little tweak.

How could I have figured this out. I'm trying to make sense out of why the variable was declared one way and then used with completely different syntax.

Would it have made a difference if I created another variable like "vMyVariable", assigned it the value and just referenced vMyVariable, or what?

Thanks so much for any comments. Anythings gotta help a bit at this point.

I'm trying to make sense out of why the variable was declared one way and then used with completely different syntax.

In creating the variable vCCI14_of_HLC3 in line 10 of the efs you are just declaring an object of CCIStudy() and assigning all the functions and properties of that object to that variable.
Using vCCI14_of_HLC3 alone to retrieve the CCI value is not enough because that is only an object hence you have to use the getValue() command. That is where vCCI14_of_HLC3.getValue(CCIStudy.CCI) comes into play. The CCIStudy.CCI part in the command is referencing a variable inside of the CCIStudy object.
In this case the variable is only one but if for example you were using the ADX object you would have three variables ie ADXDMStudy.ADX, ADXDMStudy.PDI and ADXDMStudy.NDI.

How could I have figured this out

Actually that information is provided in the Builtin Study Functions.section under EFS Function Reference in the EFS Help Center & Library.
Also if you had used the Formula Wizard to create that conditional statement you would have seen that it would have used exactly the same syntax.
Lastly if you look at the builtin efs(s) in the Builtin folders in Formulas you will see that in each one there is a comment section that provides the correct syntax to be used in the scripts.

Thank you!

Alexis,

This helps immensely. I keep trying to learn how to code but keep hitting stumbling blocks. As long as I'm patient and there are community members willing to answer, I keep making progress.

Now, if only trading were coming along so well, LOL.
