Running a strategy from a Jupyter Notebook about gryphon

[garethdmm]

I don't think you could do this today, but it's something that a moderate-scale refactor could probably achieve.

The logic for booting the strategy engine and running a strategy is split between 3-4 modules right now in gryphon.execution

• app ~ parses command line arguments, dispatches to live_runner
• live_runner ~ does a lot of clerical work to set up the harness and the tick loop
• harness/harness ~ main overseer of the strategy

The main effort for such a refactor would be in live_runner, which is quite complex right now. There really are a lot of things that need to be set up in the runtime environment in order to run a strategy.

There may be difficult product questions that come up in such an effort too. Like, does sending SIGINT signal to a strategy still work in jupyter? If not how are we going to control it once it's in operation?
