There's still a ton to polish (and some bugs to fix) but this is a first working draft of a real-time option chain! Insights and todos: - `kivy` widgets need to be cached and reused (eg. rows, cells, etc.) for speed since it seems creating new ones constantly is quite taxing on the CPU - the chain will tear down and re-setup the option data feed stream each time a different contract expiry button set is clicked - there's still some weird bug with row highlighting where it seems rows added from a new expiry set (which weren't previously rendered) aren't being highlighted reliably |

piker
Trading gear for hackers.
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 shellTo start the real-time index ETF watchlist with the robinhood backend:
piker watch indexes -l infoIf you want to see super granular price changes, increase the broker quote query rate with -r:
piker watch indexes -l info -r 10It is also possible to run the broker-client micro service as a daemon:
pikerd -l infoThen start the client app as normal:
piker watch indexes -l infoLaggy distros
For those running pop-culture distros that don't yet ship python3.7 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 real-time trading and financial analysis.
It tries to use as much cutting edge tech as possible including (but not limited to):
- Python 3.7+
