Description¶

Community.Components is a library of studies, classes, functions, and in general, "methods". Anything that doesn't fit as an Indicator, Visualizer, or Commission structure can be added here. Like Indicators, the most simple methods should be reserved for programming "on the fly" so as not to over populate the library with short snippets of generally non-useful code.

Discuss and suggest your ideas on the Forum.
