Tyler Goodlet 853e8d4466 Process framed ticks by type in main graphics loop
We are already packing framed ticks in extended lists from
the `.data._sampling.uniform_rate_send()` task so the natural solution
to avoid needless graphics cycles for HFT-ish feeds (like binance) is
to unpack those frames and for most cases only update graphics with the
"latest" data per loop iteration. Unpacking in this way also lessens
nested-iterations per tick type.

Btw, this also effectively solves all remaining issues of fast tick
feeds over-triggering the graphics loop renders as long as the original
quote stream is throttled appropriately, usually to the local display
rate.

Relates to #183, #192

Dirty deats:
- drop all per-tick rate checks, they were always somewhat pointless
  when iterating a frame of ticks per render cycle XD.
- unpack tick frame into ticks per frame type, and last of each type;
  the lasts are used to update each part of the UI/graphics by class.
- only skip the label update if we can't retrieve the last from from a
  graphics source array; it seems `chart.update_curve_from_array()`
  already does a `len` check internally.
- add some draft commented code for tick type classes and a possible
  wire framed tick data structure.
- move `chart_maxmin()` range computer to module level, bind a chart to
  it with a `partial.`
- only check rate limits in main quote loop thus reporting actual
  overages
- add in commented logic for only updating the "last" cleared price from
  the most recent framed value if we want to eventually (right now seems
  like this is only relevant to ib and it's dark trades: `utrade`).
- rename `_clear_throttle_rate` -> `_quote_throttle_rate`, drop
  `_book_throttle_rate`.

piker

trading gear for hackers.

gh_actions

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

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

focus and features:

  • 100% federated: your code, your hardware, your data feeds, your broker fills.
  • zero web: low latency, native software that doesn't try to re-invent the OS
  • maximal privacy: prevent brokers and mms from knowing your planz; smack their spreads with dark volume.
  • zero clutter: modal, context oriented UIs that echew minimalism, reduce thought noise and encourage un-emotion.
  • first class parallelism: built from the ground up on next-gen structured concurrency primitives.
  • traders first: broker/exchange/asset-class agnostic
  • systems grounded: real-time financial signal processing that will make any queuing or DSP eng juice their shorts.
  • non-tina UX: sleek, powerful keyboard driven interaction with expected use in tiling wms
  • data collaboration: every process and protocol is multi-host scalable.
  • fight club ready: zero interest in adoption by suits; no corporate friendly license, ever.

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; join the cause.

install

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

for a development install:

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

install for tinas

for windows peeps you can start by getting conda installed and the C++ build toolz on your system.

then, crack a conda shell and run the following commands:

conda create piker --python=3.9
conda activate piker
conda install pip
pip install --upgrade setuptools
cd dIreCToRieZ\oF\cODez\piker\
pip install -r requirements -e .

in order to look coolio in front of all ur tina friends (and maybe want to help us with testin, hackzing or configgin), install vscode and setup a coolio tiled wm console so you can start living the life of the tech literate..

provider support

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

  • IB via ib_insync
  • binance and kraken for crypto over their public websocket API
  • questrade (ish) which comes with effectively free L1

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:

piker -l info -b kraken -b binance chart btcusdt.binance --pdb

this runs the main chart (currently with 1m sampled OHLC) in in debug mode and you can practice paper trading using the following micro-manual:

order_mode (

edge triggered activation by any of the following keys, mouse-click on y-level to submit at that price ):

  • f/ ctl-f to stage buy
  • d/ ctl-d to stage sell
  • a to stage alert
search_mode (

ctl-l or ctl-space to open, ctl-c or ctl-space to close ) :

  • begin typing to have symbol search automatically lookup symbols from all loaded backend (broker) providers
  • arrow keys and mouse click to navigate selection
  • vi-like ctl-[hjkl] for navigation

you can also configure your position allocation limits from the sidepane.

run in distributed mode

start the service manager and data feed daemon in the background and connect to it:

pikerd -l info --pdb

connect your chart:

piker -l info -b kraken -b binance chart xmrusdt.binance --pdb

enjoy persistent real-time data feeds tied to daemon lifetime. the next time you spawn a chart it will load much faster since the data feed has been cached and is now always running live in the background until you kill pikerd.

if anyone asks you what this project is about

you don't talk about it.

how do i get involved?

enter the matrix.

how come there ain't that many docs

suck it up, learn the code; no one is trying to sell you on anything. also, we need lotsa help so if you want to start somewhere and can't necessarily write serious code, this might be the place for you!
