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.
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):
- latest python for glue
- trio for structured concurrency
- tractor for distributed, multi-core, real-time streaming
- marketstore for historical and real-time tick data persistence and sharing
- techtonicdb for L2 book storage
- Qt for pristine high performance UIs
- pyqtgraph for real-time charting
numpy
andnumba
for fast numerics
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...
- webull via the reverse engineered public API
- yahoo via yliveticker
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 buyd
/ctl-d
to stage sella
to stage alert
search_mode
(ctl-l
orctl-space
to open,ctl-c
orctl-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!
