Formula Wizard problem

[cod0973]

I just installed 7.9 and received an error about the bolinger band class not found when I create a system under the wizard.

Please advise.

Thanks

Are you creating the formula from scratch? Are you opening an existing efs? Describe with as much detail as possible the steps you are taking that generate the error.
FWIW I just created a Bollinger efs using the Formula Wizard without receiving any error messages and the efs is working without any problems

more info on error

* I removed esignal and reinstaled the current version.
* I created a new study from the wizard.
* I added the bolinger band and envelope studies.
* I then added some conditions based upon the two.

When I attach the study to the chart, I receive an error that states "class not found."

The line referenced is the line with the new bollinger band study.

"Wizard\bb1.efs, line10: Can not find internal class to construct builtin study."

line 10:
var vBollinger20 = new BollingerStudy(20,0,"Close", 2);

I can replicate the problem you are having. It happens with some studies if they are not the first one being declared.
In the mean time here is a workaround. Once you have completed setting up the studies with the Formula Wizard save the efs and close the Formula Wizard. Then open the efs with the Editor and add new before the name of each study that does not have this. For example change
var vEnv20 = EnvelopeStudy(20, 0, "Close", false, 1);
to
var vEnv20 = new EnvelopeStudy(20, 0, "Close", false, 1);
That will fix the problem for the time being

Hi, this has been fixed in v7.9.1, due out in May.
