@lppkarl said "For the importer, it's architecturally well to divide different importers into different pieces, as a make-all-things-atomic developer, I can't agree more on this. But I wonder if it would be too small for each importer to have its own package. I mean the importer itself only implements a single method, and it's just an adapter to other stock data importing library, e.g. The Trady.Importer.Quandl is referencing Quandl.NET (also 1 of my project). It would have some overhead for users to install some/all of them which may not worth the division. However, we can do this by seperating them into 2 sets, one is Trady.Importer.dll for all bundled, the other is Trady.Importer.xxx.dll for different importers. Is it OK for you for this approach?"

Fully agree with you! Architecture would be the enemy of being simple :)
Let's do it as you suggested.

@fernaramburu , ok, i would work on the Trady.Importer.dll first & the separated dlls later :)

The importers have been completed, waiting for merging to "master" when #3 is done
