rigorous install on ``nixos`` using ``poetry2nix`` ************************************************** TODO! hacky install on nixos ********************** `NixOS` is our core devs' distro of choice for which we offer a stringently defined development shell envoirment that can be loaded with:: nix-shell develop.nix this will setup the required python environment to run piker, make sure to run:: pip install -r requirements.txt -e . once after loading the shell install wild-west style via `pip` ********************************* ``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 . 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!
