Plot results of EFS from Study

[rayl542921]

Hello, need a little help please. TIA

Basically need to plot a new efs that takes the results of an EFS (i've developed) which uses a Study (i.e. cci) as the data source.

var cciStudy = new CCIStudy(6, "H+L+C/3");

>>>>'("H+L+C/3")', is incorrect, what is correct syntax?


var emaOfCCI = new MAStudy(13, 0, cciStudy, CCIStudy.CCI, MAStudy.EXPONENTIAL);

function main() {
return emaOfCCI.getValue(MAStudy.MA);
}

>>>>Instead of 'MAStudy' above i'd like to use an EFS that i've developed, how would that look?

var XXX.EFSStudyOfCCI = new XXX.EFSStudy(13, 0, cciStudy, CCIStudy.CCI, XXX.EFSStudy);

>>>TIA!

("H+L+C/3") is incorrect, what is correct syntax?

var cciStudy = new CCIStudy(6, "HLC/3");

As to your second question that depends on the study and the information you give is insufficient to provide an example. Irrespective unless it is a builtin study it is unlikely that it will be using that syntax (or a similar one). If instead it is a builtin study you can see if it is possible to do it with the Formula Wizard

EFS study to utilize

A,

Thanks for your help, very much apprecaited.

below is the code i generated w/ wizard for the CCI, i just need to figure out how to get the LSMA (attached file) of CCI, never used a EFS in this fashion previously.

Yikes! here it is...

A,

Thxs. oops on my part, could not get that attached...TIA!

Basically looking to take the LSAM of the CCI, thanks again!

The script you enclosed only calls the efs that actually performs the LSMA calculations.
Anyhow I found a copy and have attached the modified version that I think will do what you asked.
At this time the CCI study is set for a fixed Length of 20 which can only be modified using the Editor. You can however add your own functionParameter(s) if you want to be able change the parameters through Edit Studies.
Save the efs to the Downloads subfolder folder of Formulas.

You will also need to change the "calling" efs (ie the one you posted).
Here enclosed is the revised script that is now for a non-price study and that calls the modified LSMA_woodie-cci.efs
