Tyler Goodlet 7fe62690b9 Draw bars using `QPainterPath` magic 
This gives a massive speedup when viewing large bar sets (think a day's
worth of 5s bars) by using the `pg.functions.arrayToQPath()` "magic"
binary array writing that is also used in `PlotCurveItem`.  We're using
this same (lower level) function directly to draw bars as part of one
large path and it seems to be painting 15k (ish) bars with around 3ms
`.paint()` latency. The only thing still a bit slow is the path array
generation despite doing it with `numba`. Likely, either having multiple
paths or, only regenerating the missing backing array elements should
speed this up further to avoid slight delays when incrementing the bar
step.

This is of course a first draft and more cleanups are coming.

piker

trading gear for hackers.

gh_actions

piker is a broker agnostic, next-gen FOSS toolset for real-time trading targeted at hardcore Linux users.

we use as much bleeding edge tech as possible including (but not limited to):

focus and features:

  • zero web, cloud or "backtesting frameworks" (aka yabf)
  • zero self promotion (aka pump); expected throughout the community
  • 100% federated: your code, your hardware, your data feeds, your broker fills
  • broker/exchange/asset-class agnostic
  • privacy
  • real-time financial signal processing from the ground up
  • high quality, attractive, native UX with expected use in tiling wms
  • sophisticated rt charting and data sharing facilities
  • geared for collaboration within trader communities
  • zero interest in adoption by suits; no corporate friendly license, ever.
  • not built for sale; built for people

fitting with these tenets, we're always open to new framework suggestions and ideas.

building the best looking, most reliable, keyboard friendly trading platform is the dream. feel free to pipe in with your ideas and quiffs.

install

piker is currently under heavy pre-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 new components within trio.

for a development install:

git clone git@github.com:pikers/piker.git
cd piker
virtualenv env
source ./env/bin/activate
pip install -e .

broker Support

for live data feeds the in-progress set of supported brokers is:

  • IB via ib_insync
  • questrade which comes with effectively free L1
  • kraken for crypto over their public websocket API

coming soon...

if you want your broker supported and they have an API let us know.

check out our charts

bet you weren't expecting this from the foss bby:

piker -b kraken chart XBTUSD

if anyone asks you what this project is about

you don't talk about it.

how do i get involved?

enter the matrix.

learning the code is to your benefit and acts as a filter for desired users; many alpha nuggets within.
