BuiltIn CCI Error Code

[huntergatherer]

Setting length on the BuiltIn CCI indicator to a number > 1000
I get an error " line 40 parameter 1 invalid ". Why ?

That is likely due to some limitation set internally in the legacy CCIStudy() function.
Use the customCCI formula that is in the EFS2 Custom folder and that does not appear to have this limitation

I put some time into adding alerts to the builtinCCI. Everything was working fine until I ran into the limitation of 1000 bars that CCIStudy can use. Now I have to start over with the customCCI that uses array code.

I can't get an alert to fire. Do I need a getvalue after xCCI.getValue???? < -100 or is it something else ?

var fpArray = new Array();

function preMain() {

One reason you are not getting any alerts is because your conditions are enclosed inside the bInit routine which is executed once only when the formula is first loaded in the chart [or after a Reload].
You will need to move your conditions outside of that routine so that they are evaluated on each tick
Also you need to use the getValue() method to retrieve the values of a Series Object. See this article in the EFS KnowledgeBase for general information on the Series Object and the available methods. See also this article in the EFS KnowledgeBase for information specific to the cci() function together with examples of its use

I moved the conditionals outside the blnit block and set var nCCI to hold xCCI value but the only alert I get is if I use zero < or > in the conditional. The alert is cci is > than 0 even if the cci < 0. As far as I can tell I have everything as in the cci() specific link you gave for syntax.

You omitted to include a 0 in xCCI.getValue() to retrieve the current value of the xCCI series
