Any form of feedback will be greatly appreciated.


How about Polygonio_IO? That will make it clear that it is not another geometry IO package.

To your point, from the name I did assume it was a package for reading shapefiles, wkt, … etc.


Hmmm never considered that naming effect. I will probably hit up the registry team up to see if a name switch was possible.

do you have options data? I’m interested in Implied volatility. Nice work.

I plan on adding the options API. I have just seen it.

This name is really misleading. No polygons are involved, as I finally gleaned from the repo website.

OUTSTANDING!!! We’ve just been looking at Polygon.io as a source of test data for our trading augmentation tool. WELL DONE getting this up and running. We use Implied volatility as a metric and you might have made doing this VERY easy. As to the name change, could I suggest DeadParrot.jl :slight_smile:

I will also have to look into the name changing request to avoid any confusion.


The service is called Polygon.io so I don’t see how the package is improperly named. If it is misleading, that is not your fault. The post itself makes very clear what the package does

That was the main reason why I settled on that name. Named after the service.


@PyDataBlog huge FAN!!! Never mind what this ends up being called ( deadparrot.jl :slight_smile: ) I’m going to be using it in my first julia program. It’s EXACTLY what I have been looking for. Marry your package with Pluto.jl, Dagger.jl, my laziness and we have a 2022 project. OUTSTANDING!
thanks again
