# bankroll [![PyPI version](https://badge.fury.io/py/bankroll.svg)](https://badge.fury.io/py/bankroll) [![CircleCI](https://circleci.com/gh/bankroll-py/bankroll.svg?style=svg&circle-token=c2eceb857210b420215d7fdba4aa480e72c57fc3)](https://circleci.com/gh/bankroll-py/bankroll)

Command line interface and notebook utilities to **ingest portfolio and other data from multiple brokerages, and analyze it**.

This is the frontend to the [bankroll](https://github.com/bankroll-py) project, which is comprised of several libraries that can also be used on their own.

**Table of contents:**

1. [Installation](#installation)
1. [Connecting to brokers](#connecting-to-brokers)
   1. [Interactive Brokers](#interactive-brokers)
   1. [Charles Schwab](#charles-schwab)
   1. [Fidelity](#fidelity)
   1. [Vanguard](#vanguard)
   1. [(your broker here)](#your-broker-here)

1. [Extending `bankroll`](#extending-bankroll)

# Installation

To install the `bankroll` command line utility, select from [the list of available brokerage plugins](https://github.com/bankroll-py?q=bankroll-broker-), and run `pip install` with those brokerages listed as [extras](https://packaging.python.org/tutorials/installing-packages/#installing-setuptools-extras).

For example, to install `bankroll` with support for [Interactive Brokers](#interactive-brokers) and [Charles Schwab](#charles-schwab):

```
pip3 install bankroll[ibkr,schwab]
```

Or from the repository root, if you have cloned the code:

```
pip3 install .[ibkr,schwab,fidelity]
```

Once installed (and presuming your Python path is set up correctly), the command line tool can be invoked directly:

```
bankroll --help
```

# Connecting to brokers

After being set up, `bankroll` can be used from the command line to bring together data from multiple brokerages.

For example, to show all positions held in both Interactive Brokers and Charles Schwab:

```
bankroll \
  --ibkr-tws-port 7496 \
  --schwab-positions ~/Positions-2019-01-01.CSV \
  --schwab-transactions ~/Transactions_20190101.CSV \
  positions
```

Run with `--help` to see all options:

```
bankroll --help
```

## Interactive Brokers

[Interactive Brokers](http://interactivebrokers.com) (sometimes abbreviated as IB or IBKR) offers a well-supported [API](https://interactivebrokers.github.io/), which—along with [ib_insync](https://github.com/erdewit/ib_insync)—makes it possible to load up-to-date portfolio data and request real-time information about particular securities.

For `bankroll`, this functionality is implemented via the [bankroll-broker-ibkr](https://github.com/bankroll-py/bankroll-broker-ibkr) plugin:
```
pip3 install bankroll[ibkr]
```

To load data from Interactive Brokers, [one of IB's trading applications](https://interactivebrokers.github.io/tws-api/initial_setup.html)—Trader Workstation or IB Gateway—must be running and logged-in to accept API connections. You may wish to use [IBC](https://github.com/IbcAlpha/IBC) to automate the startup and login of these applications.

Once Trader Workstation or IB Gateway is running, and [API connections are enabled](https://interactivebrokers.github.io/tws-api/initial_setup.html#enable_api), provide the local port number to `bankroll` like so:

```
bankroll \
  --ibkr-tws-port 7496 \
  [command]
```

### Querying trade history

IB's [Trader Workstation API](https://interactivebrokers.github.io/tws-api/) does not support retrieving information about an account's historical trades, so `bankroll` must use their [Flex Web Service](https://www.interactivebrokers.com/en/software/am/am/reports/flex_web_service_version_3.htm).

To set this up, log in to [Account Management](https://www.interactivebrokers.com/portal), then browse to _Settings_ → _Account Settings_ in the sidebar:

In the _Reporting_ section of this page, click the gear to configure _Flex Web Service_:

**Once configured, copy the _Current Token_ for use on the command line.**

Then, you must save a query for `bankroll` to use. Back in the sidebar, browse to _Reports_ → _Flex Queries_:

Click the gear to configure _Custom Flex Queries_:

Create a new Trade Confirmation Flex Query Template:

Pick a name of your choosing, then make sure the _Date Period_ reflects the historical period you care about (e.g., _Last 365 Calendar Days_):

Under _Sections_, click _Trade Confirmations_ and enable everything in the dialog which appears:

**After saving your query, expand it in the list to view and copy the _Query ID_ for use on the command line.**

With the token and the query ID from your account, historical trades can be downloaded:

```
bankroll \
  --ibkr-flex-token [token] \
  --ibkr-trades [query ID] \
  activity
```

### Querying dividend history

_This workflow [will be simplified](https://github.com/bankroll-py/bankroll/issues/36) in the future._

To incorporate the history of dividend payments in your portfolio, follow the same steps for the [Trade Confirmation Flex Query](#querying-trade-history), but create an Activity Flex Query instead.

The only section which needs to be enabled is _Change in Dividend Accruals_:

Pass your existing token, and the new query's ID, on the command line:

```
bankroll \
  --ibkr-flex-token [token] \
  --ibkr-activity [query ID] \
  activity
```

## Charles Schwab

[Charles Schwab](https://www.schwab.com) does not offer an API, but it does provide [CSV](https://en.wikipedia.org/wiki/Comma-separated_values) files for export, which `bankroll` can then import.

This functionality is implemented via the [bankroll-broker-schwab](https://github.com/bankroll-py/bankroll-broker-schwab) plugin:
```
pip3 install bankroll[schwab]
```

Browse to the "Positions" and/or "Transactions" screen:

Click the "Export" link in the top-right:

Then provide the paths of either or both these downloaded files to `bankroll`:

```
bankroll \
  --schwab-positions ~/path/to/Positions.CSV \
  --schwab-transactions ~/path/to/Transactions.CSV \
  [command]
```

## Fidelity

[Fidelity](https://www.fidelity.com) is supported through a similar facility as [Schwab](#charles-schwab).

This functionality is implemented via the [bankroll-broker-fidelity](https://github.com/bankroll-py/bankroll-broker-fidelity) plugin:
```
pip3 install bankroll[fidelity]
```

* To export position data, [download from the Portfolio Positions page](https://www.fidelity.com/webcontent/ap002390-mlo-content/18.09/help/learn_portfolio_positions.shtml#canidownload).
* To export transactions data, [download from the History page](https://www.fidelity.com/customer-service/faqs-exporting-account-information#).

More detailed instructions have yet to be written—[contributions welcome](CONTRIBUTING.md)!

## Vanguard

[Vanguard](https://investor.vanguard.com) is a **work in progress**, and may not be as fully-featured as the other brokerages listed here. Support is being developed in the [bankroll-broker-vanguard](https://github.com/bankroll-py/bankroll-broker-vanguard) plugin:

## (your broker here)

`bankroll` intends to abstract away broker-specific details as much as possible, to minimize the work required to support each one, so if your broker isn't listed above, please consider [building a new brokerage plugin](https://github.com/bankroll-py/bankroll-broker)! We want the list to grow over time, because it's extremely useful to be able to aggregate and analyze data across multiple brokers at once.

To add a new brokerage, create a new subclass of [`AccountData`](https://github.com/bankroll-py/bankroll-broker/blob/v0.4.0/bankroll/broker/account.py), then implement the methods as required by the interface. As long as the new subclass is loaded at runtime, it will be automatically included in functionality like [data aggregation](https://github.com/bankroll-py/bankroll-broker/blob/v0.4.0/bankroll/broker/aggregator.py).

If the brokerage offers a facility to load market data, consider extending the [bankroll-marketdata](https://github.com/bankroll-py/bankroll-marketdata) interfaces as well (though this is optional).

# Saving configuration

To preserve settings across runs, all of the command-line arguments demonstrated above can also be saved into an [INI file](https://docs.python.org/3/library/configparser.html#supported-ini-file-structure). The configuration file is especially useful to store default values, because when a setting is specified in a configuration file _as well as_ on the command line, the command-line argument will take precedence.

To create a configuration, copy [`bankroll.default.ini`](bankroll/interface/bankroll.default.ini) to `~/.bankroll.ini`, or leave it in your working directory as `bankroll.ini`, then edit the file to apply your desired settings.

If you would like to store the configuration somewhere else, you can also provide custom paths via the `--config` argument on the command line.

# Extending `bankroll`

Although the command-line interface exposes a basic set of functionality, it will never be able to capture the full set of possible use cases. For much greater flexibility, you can write Python code to use `bankroll` directly, and build on top of its APIs for your own purposes.

For some examples, [see the included notebooks](notebooks/).
