Trying to use the scsf_SwingHighAndLow code and just generate an arrow on every swing low to start out.

Not sure how to make use of this study beyond including it in my file, and the couple lines of code at the bottom.

But it's giving this error when doing a remote build, and I was not able to piece together how to fix this from the forums and google yet:
test1.cpp:144:1: error: 'scsf_SwingHighAndLow' does not name a type
144 | scsf_SwingHighAndLow swingStudy(100);
| ^~~~~~~~~~~~~~~~~~~~
test1.cpp:146:20: error: 'StudyData' was not declared in this scope
146 | int CalculateStudy(StudyData std::data) {
| ^~~~~~~~~


Any help would be appreciated.
