*****************
|
||||
for windows peeps you can start by getting `conda installed`_
|
||||
and the `C++ build toolz`_ on your system.
|
||||
for windows peeps you can start by installing all the prerequisite software:
|
||||
|
||||
- install git with all default settings - https://git-scm.com/download/win
|
||||
- install anaconda all default settings - https://www.anaconda.com/products/individual
|
||||
- install microsoft build tools (check the box for Desktop development for C++, you might be able to uncheck some optional downloads) - https://visualstudio.microsoft.com/visual-cpp-build-tools/
|
||||
- install visual studio code default settings - https://code.visualstudio.com/download
|
||||
|
||||
|
||||
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 .
|
||||
mkdir code # create code directory
|
||||
cd code # change directory to code

git clone https://github.com/pikers/piker.git # downloads piker installation package from github
|
||||
cd piker # change directory to piker
|
||||
|
||||
conda create -n pikonda # creates conda environment named pikonda
|
||||
conda activate pikonda # activates pikonda
|
||||
|
||||
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..
|
||||
conda install -c conda-forge python-levenshtein # in case it is not already installed

||||
|

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\user\\AppData\\Roaming\\piker\\brokers.toml'
|
||||
|
||||
solution:
|
||||
|
||||
- navigate to file directory above (may be different on your machine, location should be listed in the error code)
|
||||
- copy and paste file from 'C:\\Users\\user\\code\\data/brokers.toml' or create a blank file using notepad at the location above
|
||||
|
||||
Visual Studio Code setup:
|
||||
|
||||
- now that piker is installed we can set up vscode as the default terminal for running piker and editing the code
|
||||
- open Visual Studio Code
|
||||
- file --> Add Folder to Workspace --> C:\Users\user\code\piker (adds piker directory where all piker files are located)
|
||||
- file --> Save Workspace As --> save it wherever you want and call it whatever you want, this is going to be your default workspace for running and editing piker code
|
||||
- ctrl + shift + p --> start typing Python: Select Interpetter --> when the option comes up select it --> Select at the workspace level --> select the one that shows ('pikonda')
|
||||
- change the default terminal to cmd.exe instead of powershell (default)
|
||||
- now when you create a new terminal VScode should automatically activate you conda env so that piker can be run as the first command after a new terminal is created
|
||||
|
||||
also, try out fancyzones as part of powertoyz for a decent tiling windows manager to manage all the cool new software you are going to be running.

running ``ib`` gateway in ``docker``
|

------------------------------------
|
||||
We have a config based on the (now defunct)
|
||||
image from "waytrade":
|
||||
|
||||
https://github.com/waytrade/ib-gateway-docker
|
||||
|
||||
To startup this image with our custom settings
|
||||
simply run the command::
|
||||
|
||||
docker compose up
|
||||
|
||||
And you should have the following socket-available services:
|
||||
|
||||
- ``x11vnc1@127.0.0.1:3003``
|
||||
- ``ib-gw@127.0.0.1:4002``
|
||||
|
||||
You can attach to the container via a VNC client
|
||||
without password auth.
|
||||
|
||||
SECURITY STUFF!?!?!
|
||||
-------------------
|
||||
Though "``ib``" claims they host filter connections outside
|
||||
localhost (aka ``127.0.0.1``) it's probably better if you filter
|
||||
the socket at the OS level using a stateless firewall rule::
|
||||
|
||||
ip rule add not unicast iif lo to 0.0.0.0/0 dport 4002
|
||||
|
||||
We will soon have this baked into our own custom image but for
|
||||
now you'll have to do it urself dawgy.

# normally the folder in which TWS is installed. However you may set
|
||||
# it to some other location if you wish (for example if you want to
|
||||
# run multiple instances of TWS with different settings).
|
||||
#
|
||||
# It is recommended for clarity that you use an absolute path. The
|
||||
# effect of using a relative path is undefined.
|
||||
#
|
||||
# Linux and macOS users should use the appropriate path syntax.
|
||||
#
|
||||
# Note that, for Windows users, you MUST use double separator
|
||||
# characters to separate the elements of the folder path: for
|
||||
# example, IbDir=C:\\IBLiveSettings is valid, but
|
||||
# IbDir=C:\IBLiveSettings is NOT valid and will give unexpected
|
||||
# results. Linux and macOS users need not use double separators,
|
||||
# but they are acceptable.
|

# If you wish to store a copy of your TWS settings on IB's
|

# servers as well as locally on your computer, set this to
|
||||
# 'yes': this enables you to run TWS on different computers
|
||||
# with the same configuration, market data lines, etc. If set
|
||||
# to 'no', running TWS on different computers will not share the
|
||||
# same settings. If no value is specified, TWS will obtain its
|
||||
# settings from the same place as the last time this user logged
|
||||
# in (whether manually or using IBC).

# Existing Session Detected Action
|
||||
# --------------------------------
|
||||
#
|
||||
# When a user logs on to an IBKR account for trading purposes by any means, the
|
||||
# IBKR account server checks to see whether the account is already logged in
|
||||
# elsewhere. If so, a dialog is displayed to both the users that enables them
|
||||
# to determine what happens next. The 'ExistingSessionDetectedAction' setting
|
||||
# instructs TWS how to proceed when it displays this dialog:
|
||||
#
|
||||
# * If the new TWS session is set to 'secondary', the existing session continues
|
||||
# and the new session terminates. Thus a secondary TWS session can never
|
||||
# override any other session.
|
||||
#
|
||||
# * If the existing TWS session is set to 'primary', the existing session
|
||||
# continues and the new session terminates (even if the new session is also
|
||||
# set to primary). Thus a primary TWS session can never be overridden by
|
||||
# any new session).
|
||||
#
|
||||
# * If both the existing and the new TWS sessions are set to 'primaryoverride',
|
||||
# the existing session terminates and the new session proceeds.
|
||||
#
|
||||
# * If the existing TWS session is set to 'manual', the user must handle the
|
||||
# dialog.
|
||||
#
|
||||
# The difference between 'primary' and 'primaryoverride' is that a
|
||||
# 'primaryoverride' session can be overriden over by a new 'primary' session,
|
||||
# but a 'primary' session cannot be overriden by any other session.
|
||||
#
|
||||
# When set to 'primary', if another TWS session is started and manually told to
|
||||
# end the 'primary' session, the 'primary' session is automatically reconnected.
|
||||
#
|
||||
# The default is 'manual'.

# Override TWS API Port Number
|
||||
# ----------------------------
|
||||
#
|
||||
# If OverrideTwsApiPort is set to an integer, IBC changes the
|
||||
# 'Socket port' in TWS's API configuration to that number shortly
|
||||
# after startup. Leaving the setting blank will make no change to
|
||||
# the current setting. This setting is only intended for use in
|
||||
# certain specialized situations where the port number needs to
|
||||
# be set dynamically at run-time: most users will never need it,
|
||||
# so don't use it unless you know you need it.

# the second factor authentication action, and login to TWS will
|

# occur automatically in read-only mode: in this mode, placing or

# managing orders is not allowed. If set to 'no', and the user is
|
||||
# enrolled in IB's account security programme, the user must perform
|
||||
# the relevant second factor authentication action to complete the
|
||||
# login.
|

# If the user is not enrolled in IB's account security programme,

# If not set, the existing TWS/Gateway configuration is unchanged.
|

# NB: this setting is really only supplied for the benefit of new TWS
|

# or Gateway instances that are being automatically installed and
|
||||
# started without user intervention (eg Docker containers). Where

# Market data size for US stocks - lots or shares
|
||||
# -----------------------------------------------
|
||||
#
|
||||
# Since IB introduced the option of market data for US stocks showing
|
||||
# bid, ask and last sizes in shares rather than lots, TWS and Gateway
|
||||
# display a dialog immediately after login notifying the user about
|
||||
# this and requiring user input before allowing market data to be
|
||||
# accessed. The user can request that the dialog not be shown again.
|
||||
#
|
||||
# It is recommended that the user should handle this dialog manually
|
||||
# rather than using these settings, which are provided for situations
|
||||
# where the user interface is not easily accessible, or where user
|
||||
# settings are not preserved between sessions (eg some Docker images).
|
||||
#
|
||||
# - If this setting is set to 'accept', the dialog will be handled
|
||||
# automatically and the option to not show it again will be
|
||||
# selected.
|
||||
#
|
||||
# Note that in this case, the only way to allow the dialog to be
|
||||
# displayed again is to manually enable the 'Bid, Ask and Last
|
||||
# Size Display Update' message in the 'Messages' section of the TWS
|
||||
# configuration dialog. So you should only use 'Accept' if you are
|
||||
# sure you really don't want the dialog to be displayed again, or
|
||||
# you have easy access to the user interface.
|
||||
#
|
||||
# - If set to 'defer', the dialog will be handled automatically (so
|
||||
# that market data will start), but the option to not show it again
|
||||
# will not be selected, and it will be shown again after the next
|
||||
# login.
|
||||
#
|
||||
# - If set to 'ignore', the user has to deal with the dialog manually.
|
||||
#
|
||||
# The default value is 'ignore'.
|

#
|
||||
# Note if set to 'accept' or 'defer', TWS also automatically sets
|

# the API settings checkbox labelled 'Send market data in lots for

# US stocks for dual-mode API clients'. IBC cannot prevent this.
|

# However you can change this immmediately by setting

# 4. TWS Auto-Closedown
|

# =============================================================================
|

#
|

# IMPORTANT NOTE: Starting with TWS 974, this setting no longer
|
||||
# works properly, because IB have changed the way TWS handles its
|
||||
# autologoff mechanism.
|

#
|

# You should now configure the TWS autologoff time to something
|
||||
# convenient for you, and restart IBC each day.
|
||||
#
|
||||
# Alternatively, discontinue use of IBC and use the auto-relogin
|
||||
# mechanism within TWS 974 and later versions (note that the
|
||||
# auto-relogin mechanism provided by IB is not available if you
|
||||
# use IBC).
|
||||
|
||||
# Set to yes or no (lower case).
|
||||
#
|

# configuration menu.
|

#
|

# no means TWS never shuts down automatically.

# NB: IB recommends that you do not keep TWS running

# continuously. If you set this setting to 'no', you may
|

# experience incorrect TWS operation.
|
||||
#
|
||||
# NB: the default for this setting is 'no'. Since this will

# should explicitly set this to 'yes' for version 974 and later.

# 5. TWS Tidy Closedown Time
|
||||
# =============================================================================
|
||||
#
|
||||
# NB: starting with TWS 974 this is no longer a useful option
|
||||
# because both TWS and Gateway now have the same auto-logoff
|
||||
# mechanism, and IBC can no longer avoid this.
|
||||
#
|
||||
# Note that giving this setting a value does not change TWS's
|
||||
# auto-logoff in any way: any setting will be additional to the
|
||||
# TWS auto-logoff.
|
||||
#
|
||||
# To tell IBC to tidily close TWS at a specified time every
|
||||
# day, set this value to <hh:mm>, for example:
|
||||
# ClosedownAt=22:00
|
||||
#
|
||||
# To tell IBC to tidily close TWS at a specified day and time
|
||||
# each week, set this value to <dayOfWeek hh:mm>, for example:
|
||||
# ClosedownAt=Friday 22:00
|
||||
#
|
||||
# Note that the day of the week must be specified using your
|
||||
# default locale. Also note that Java will only accept
|
||||
# characters encoded to ISO 8859-1 (Latin-1). This means that
|
||||
# if the day name in your default locale uses any non-Latin-1
|
||||
# characters you need to encode them using Unicode escapes
|
||||
# (see http://java.sun.com/docs/books/jls/third_edition/html/lexical.html#3.3
|
||||
# for details). For example, to tidily close TWS at 12:00 on
|
||||
# Saturday where the default locale is Simplified Chinese,
|
||||
# use the following:
|
||||
# #ClosedownAt=\u661F\u671F\u516D 12:00

# incoming API connection dialogs. The default is 'manual'.
|
||||
# NB: it is recommended to set this to 'reject', and to explicitly
|
||||
# configure which IP addresses can connect to the API in TWS's API
|

# to warn you against such blind trading.
|

# Save Settings on a Schedule
|
||||
# ---------------------------
|
||||
#
|
||||
# You can tell TWS to automatically save its settings on a schedule
|

# of your choosing. You can specify one or more specific times,
|
||||
# like this:
|
||||
#
|
||||
# SaveTwsSettingsAt=HH:MM [ HH:MM]...
|
||||
#
|
||||
# for example:
|
||||
# SaveTwsSettingsAt=08:00 12:30 17:30
|
||||
#
|
||||
# Or you can specify an interval at which settings are to be saved,
|
||||
# optionally starting at a specific time and continuing until another
|
||||
# time, like this:
|
||||
#
|
||||
#SaveTwsSettingsAt=Every n [{mins | hours}] [hh:mm] [hh:mm]
|
||||
#
|
||||
# where the first hh:mm is the start time and the second is the end
|
||||
# time. If you don't specify the end time, settings are saved regularly
|
||||
# from the start time till midnight. If you don't specify the start time.
|
||||
# settings are saved regularly all day, beginning at 00:00. Note that
|
||||
# settings will always be saved at the end time, even if that is not
|
||||
# exactly one interval later than the previous time. If neither 'mins'
|
||||
# nor 'hours' is specified, 'mins' is assumed. Examples:
|
||||
#
|
||||
# To save every 30 minutes all day starting at 00:00
|
||||
#SaveTwsSettingsAt=Every 30
|
||||
#SaveTwsSettingsAt=Every 30 mins
|
||||
#
|

# To save every hour starting at 08:00 and ending at midnight
|

#SaveTwsSettingsAt=Every 1 hours 08:00
|
||||
#SaveTwsSettingsAt=Every 1 hours 08:00 00:00
|

# Command Server Port Number
|

# used for TWS API connections. There is no good reason
|
||||
# to change this setting unless the port is used by
|
||||
# some other application (typically another instance of

# IBC). The default value is 0, which tells IBC not to
|

# start the command server

# =============================================================================
|

#
|
||||
# IBC can log information about the structure of windows
|
||||
# displayed by TWS. This information is useful when adding
|
||||
# new features to IBC or when behaviour is not as expected.
|
||||
#
|
||||
# The logged information shows the hierarchical organisation
|
||||
# of all the components of the window, and includes the
|
||||
# current values of text boxes and labels.
|
||||
#
|
||||
# Note that this structure logging has a small performance
|
||||
# impact, and depending on the settings can cause the logfile
|
||||
# size to be significantly increased. It is therefore
|
||||
# recommended that the LogStructureWhen setting be set to
|
||||
# 'never' (the default) unless there is a specific reason
|
||||
# that this information is needed.
|
||||
|
||||
|
||||
# Scope of Structure Logging
|
||||
# --------------------------
|
||||
#
|
||||
# The LogStructureScope setting indicates which windows are
|
||||
# eligible for structure logging:
|
||||
#
|
||||
# - if set to 'known', only windows that IBC recognizes
|
||||
# are eligible - these are windows that IBC has some
|
||||
# interest in monitoring, usually to take some action
|
||||
# on the user's behalf;
|
||||
#
|
||||
# - if set to 'unknown', only windows that IBC does not
|
||||
# recognize are eligible. Most windows displayed by
|
||||
# TWS fall into this category;
|
||||
#
|
||||
# - if set to 'untitled', only windows that IBC does not
|
||||
# recognize and that have no title are eligible. These
|
||||
# are usually message boxes or similar small windows,
|
||||
#
|
||||
# - if set to 'all', then every window displayed by TWS
|
||||
# is eligible.
|
||||
#
|
||||
# The default value is 'known'.
|
||||
|
||||
LogStructureScope=all
|
||||
|
||||
|
||||
# When to Log Window Structure
|
||||
# ----------------------------
|
||||
#
|
||||
# The LogStructureWhen setting specifies the circumstances
|
||||
# when eligible TWS windows have their structure logged:
|
||||
#
|
||||
# - if set to 'open' or 'yes' or 'true', IBC logs the
|
||||
# structure of an eligible window the first time it
|
||||
# is encountered;
|
||||
#
|
||||
# - if set to 'activate', the structure is logged every
|
||||
# time an eligible window is made active;
|
||||
#
|
||||
# - if set to 'never' or 'no' or 'false', structure
|
||||
# information is never logged.
|
||||
#
|
||||
# The default value is 'never'.
|
||||
|
||||
LogStructureWhen=never
|
||||
|
||||
|
||||
# DEPRECATED SETTING
|
||||
# ------------------
|
||||
#
|
||||
# LogComponents - THIS SETTING WILL BE REMOVED IN A FUTURE
|
||||
# RELEASE
|
||||
#
|
||||
# If LogComponents is set to any value, this is equivalent
|
||||
# to setting LogStructureWhen to that same value and
|
||||
# LogStructureScope to 'all': the actual values of those
|
||||
# settings are ignored. The default is that the values
|
||||
# of LogStructureScope and LogStructureWhen are honoured.

A faster, append friendly version of ``pyqtgraph.PlotCurveItem``

|
||||
A faster, simpler, append friendly version of
|
||||
``pyqtgraph.PlotCurveItem`` built for highly customizable real-time
|
||||
updates.
|
||||
|
||||
The main difference is avoiding regeneration of the entire
|
||||
historical path where possible and instead only updating the "new"
|
||||
segment(s) via a ``numpy`` array diff calc. Further the "last"
|
||||
graphic segment is drawn independently such that near-term (high
|
||||
frequency) discrete-time-sampled style updates don't trigger a full
|
||||
path redraw.
|
||||
This type is a much stripped down version of a ``pyqtgraph`` style
|
||||
"graphics object" in the sense that the internal lower level
|
||||
graphics which are drawn in the ``.paint()`` method are actually
|
||||
rendered outside of this class entirely and instead are assigned as
|
||||
state (instance vars) here and then drawn during a Qt graphics
|
||||
cycle.
|
||||
|
||||
The main motivation for this more modular, composed design is that
|
||||
lower level graphics data can be rendered in different threads and
|
||||
then read and drawn in this main thread without having to worry
|
||||
about dealing with Qt's concurrency primitives. See
|
||||
``piker.ui._flows.Renderer`` for details and logic related to lower
|
||||
level path generation and incremental update. The main differences in
|
||||
the path generation code include:
|
||||
|
||||
- avoiding regeneration of the entire historical path where possible
|
||||
and instead only updating the "new" segment(s) via a ``numpy``
|
||||
array diff calc.
|
||||
- here, the "last" graphics datum-segment is drawn independently
|
||||
such that near-term (high frequency) discrete-time-sampled style
|

updates don't trigger a full path redraw.
