'''
|
||||
This algorithm requires an additional library (ta-lib) beyond those required by catalyst.
|
||||
Install it first by running:
|
||||
$ pip install TA-Lib
|
||||
|
||||
If you get build errors like "fatal error: ta-lib/ta_libc.h: No such file or directory"
|
||||
it typically means that it can't find the underlying TA-Lib library and needs to be installed.
|
||||
See https://mrjbq7.github.io/ta-lib/install.html for instructions on how to install
|
||||
the required dependencies.
