Share New Research 
Two questions that I can't seem to find answers to:
- Is there a specification posted for the web API that API.cs and api.py is based off of?
- Is it possible to add to the "backtests/create" endpoint the ability to take a map of parameters to values? This would make the API a lot more powerful. Right now I have to copy a locally modified backtest with a new param value and then send a file contents update request -> compile request -> create backtest request when all I want to do is use the already compile backtest but with a new param value

Hey Ari,
We officially do not support parameter optimization on the dedicated nodes. They are unlimited within "fair use" as we keep the costs down by averaging the costs over the community. We launched optimization last week to explicitly support this with a sustainable per use business model.
There is no specification for the API, I'd welcome your help drafting the YAML for it though. That's a good idea =)
Happy New Year

OK.
Yes, I noticed the new optimization feature that was released after I posted this and excellent initial release. Are there plans to add new optimization models and/or additional methods to specify how the parameters change (for instance I have a parameter that should step non-linearly.
Happy to contribute an OpenAPI/Swagger model of the API from at least what I can see on the client end. Obviously, if there are any params or endpoints that are handled on the backend but not yet added to the C#/Python clients then these would be missing.

Hey Ari, yes we've also already implemented other techniques in LEAN and are integrating them to the IDE this week.
