Tyler Goodlet ef90d7f106 Add remote actor error handling and parent re-raising 
Command requests are sent out and responses are handled in a "message
loop" where each command is associated with a "caller id" and multiple
cmds and results are multiplexed on the came inter-actor channel. When
a cmd result arrives it is pushed into a local queue and delivered to the
appropriate calling actor's task. Errors from a remote actor are always shipped
in an "error" packet back to their spawning-parent actor such that any error
in a subactor is always raised directly in the parent. Based on the
first response to a cmd (either a 'return' or 'yield' packet) the caller
side portal will retrieve values by wrapping the local response queue in
either of an async function or generator as appropriate.

Anti-fragile trading gear for hackers, scientists, stay-at-home quants and underpants warriors.

Install

piker is currently under heavy alpha development and as such should be cloned from this repo and hacked on directly.

A couple bleeding edge components are being used atm pertaining to async ports of libraries for use with trio.

Before installing make sure you have pipenv. For a development install:

git clone git@github.com:pikers/piker.git
cd piker
pipenv install --dev -e .
pipenv shell

To start the real-time index ETF watchlist:

piker watch indexes -l info

If you want to see super granular price changes, increase the broker quote query rate with -r:

piker watch indexes -l info -r 10

It is also possible to run the broker-client micro service as a daemon:

pikerd -l info

Then start the client app as normal:

piker watch indexes -l info

Laggy distros

For those running pop-culture distros that don't yet ship python3.6 you'll need to install it as well as kivy source build dependencies since currently there's reliance on an async development branch.

Tech

piker is an attempt at a pro-grade, next-gen open source toolset for trading and financial analysis. As such, it tries to use as much cutting edge tech as possible including Python 3.6+ and trio.
