add recipe for mplfinance

[DanielGoldfarb]

This is my first time contributing a package to conda-forge.

I think I've got everything right. The only thing I am aware of having doubts about is the license file. I entered a url to the license. Not sure if I should rather be doing something else.

My recipe was generated with conda skeleton pypi mplfinance with a small amount of manual editing after that. I used conda-build and anaconda upload, and then tested installing from https://anaconda.org/DanielGoldfarb/mplfinance and it worked.

Let me know if there is anything else I need to do in order to get this into conda-forge. Thank you.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipes/mplfinance) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipes/mplfinance:

• License is not an SPDX identifier (or a custom LicenseRef) nor an SPDX license expression.

Documentation on acceptable licenses can be found here.

Hi @conda-forge/help-python
I could use some help. I see some checks failed. The error message (for linux_64 linux, for example) is bash exited with code '1' ...
I have no idea what was run that exited with code '1'. Please help. I'm a first time conda-forge contributor. Thank you. --Daniel

Took some poking around, but I managed to find the build log on dev.azure.com and it was clearly complaining about the license file. So trying a different specification for the license file.

[DanielGoldfarb]

I am now getting the error:

ValueError: License file given in about/license_file (/home/conda/staged-recipes-copy/recipes/mplfinance/https://github.com/matplotlib/mplfinance/blob/master/LICENSE) does not exist in source root dir or in recipe root dir (with meta.yaml)

but the link (https://github.com/matplotlib/mplfinance/blob/master/LICENSE) is the actual license file.

I am beginning to get the idea that I need to copy the license file into my recipes directory. I'd like to avoid doing that if possible, because I don't want to have two license files that can possibly get out of sync: one in the matplotlib/mplfinance repostory, and one in the conda-forge/staged-recipes repository.

@conda-forge-coordinator - please advise. thank you.

@synapticarbors
Joshua, What is the normal time expectation for a PR like this to get merged (once review changes have been made)??
Thanks. --Daniel

@DanielGoldfarb -- Thank you for your contribution to conda-forge! Once the feedstock for this package is created if you run into any problems, please don't hesitate to ping the team for help.

In terms of how long a PR takes to get merged, it's highly dependent on how busy the reviewers are. We try to turn most PRs around within a day or so when possible.
