Weird, I recompiled it on a different maschine and set it to release mode, tested it on my girlfriends laptop with a clean updated install of Sierrachart. Works fine again for me, are you sure you put it into the Data Folder? Try this file, let me know if it works EDIT: You should get the error message when you delete a .dll while its saved onto a chart within a chartbook, because then sierra cant find the file. 1) Delete the old .dll 2) Remove the old study from your studylist on the chart you loaded it onto 3) Copy the new .dll into C:\SierraChart\Data or wherever your data folder is for sierra 4) Load it into the chart by adding it from the studies window. 5) Done

I cant load the file. I can see it under Custom study but load it on the chart. The error 126 shows up in the massage log each time I click and open customs study's. Regards Outlander

This is very odd, just let another friend test it and he says it works fine (he had to update sierrachart though).

How to Use an Advanced Custom Study and Study Collections - Sierra Chart

Basically means you are messing up with putting the file in the correct folder.

Quoting 

This error means the DLL (dynamic link library) file that contains the Advanced Custom Study or Studies that you are using could not be found. You will need to obtain the specified DLL file and save it to your Sierra Chart Data Files Folder. Please see Step #1 above for instructions. When you save the DLL file to the Sierra Chart Data Files Folder, make certain it has a DLL file extension. Software which blocks malicious software such as antivirus software, can also potentially block the use of a downloaded DLL file and this can also cause this same error message. If you are unable to resolve this error, you will need to remove the Advanced Custom Study or Studies from your chart or charts to prevent the error from appearing again. To do this, go to one of your charts, select Analysis >> Studies to view the Chart Studies window. In the Studies to Graph section, select Custom DLL Study and press Remove to remove the study. Remove all of the Custom DLL Study studies from the list and press OK to save the settings. You will need to do this for each chart that has a Custom DLL Study study which is causing the error.

Just in case i am attaching the source code for you so you can compile it yourself.

I have put the file in the data folder. You can see it in my picture. But the add button is gray so I cant load it. Regards Outlander

Not sure whats going on Outlander, Update Sierrachart, and compile the sourcecode and you should be good to go.

What do you mean by compile ?
Ordinary is enought if you put file in data folder.

Sorry for all the trouble. The problem must be in my end. I have only used the spreadsheet and don't know how to make own studys or how to compile. Regards Outlander

I was also unable to add the DLL (grayed out here too), but after compiling the Source.cpp file I was able to add the study.

I've attached the DLL resulting from compiling the source file.

Hope this helps

Btw: I didn't really mess around much with the study once I added it, but it appears to be in order. Something mildly interesting is that the original DLL was 42kb whereas my compiled version is only 20kb.

Finally got it to work

@omni72 ,

Thanks for solving the issue for them, I've uploaded 2 files, one in Debug mode which is 44kb for me, and one in release mode which is 13 KB for me.

You can test this yourself by firing up Visual studio/Visual Studio Express and compiling it 2 times one in Release and one in Debug mode =/

The file I've attached now is 13Kb big and compiled in release mode. Yet oddly enough both files work splendidly for me on 3 seperate maschines and for my friends aswell. Any idea as to what may have caused issues with Lemons and Outlander
