*****************
 | 
			
		||||
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
 | 
			
		||||
 | 
			
		||||
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::
 | 
			
		||||
 | 
			
		||||
    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
 |

 |

    conda install pip # may already be installed
 | 
			
		||||
    pip # will show if pip is installed
 | 
			
		||||

    pip install -e . -r requirements.txt # install piker in editable mode
 |

    conda create piker --python=3.9
 |

 |

    pip install -r requirements -e .
 | 
			
		||||
 | 
			
		||||
test Piker to see if it is working::
 |

 | 
			
		||||

 | 
			
		||||

 | 
			
		||||
    
 | 
			
		||||
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.
 | 
			
		||||
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

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.

# 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.

# 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

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

# API connection dialogs. If set to 'reject', IBC

# set to 'manual', the user must decide whether to accept or reject

# NB: it is recommended to set this to 'reject', and to explicitly

# 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
 | 
			
		||||
#
 | 
			
		||||
# To save every 90 minutes starting at 08:00 up to and including 17:43
 | 
			
		||||
#SaveTwsSettingsAt=Every 90 08:00 17:43

# Do NOT CHANGE THE FOLLOWING SETTINGS unless you

		||||
# such as "STOP". DO NOT set this to the port number
 |

# used for TWS API connections. There is no good reason
 | 
			
		||||
# to change this setting unless the port is used by

 |

# 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'.

# 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

    A faster, simpler, append friendly version of

 | 
			
		||||
    updates.
 | 
			
		||||
 | 
			
		||||
    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.
 | 
			
		||||
    Generate a "step mode" curve aligned with OHLC style bars
