# SwiftBeanCountWealthsimpleMapper
[](https://github.com/Nef10/SwiftBeanCountWealthsimpleMapper/actions?query=workflow%3A%22CI%22) [](https://nef10.github.io/SwiftBeanCountWealthsimpleMapper/) [](https://github.com/Nef10/SwiftBeanCountWealthsimpleMapper/blob/main/LICENSE) [](https://github.com/Nef10/SwiftBeanCountWealthsimpleMapper/releases)  
### ***This project is part for SwiftBeanCount, please check out the main documentation [here](https://github.com/Nef10/SwiftBeanCount).***
## What
This is a small library to convert downloaded data from Wealthsimple (via [WealthsimpleDownloader](https://github.com/Nef10/WealthsimpleDownloader)) to the Beancount format (via [SwiftBeanCountModel](https://github.com/Nef10/SwiftBeanCountModel)).
## Beancount meta data
The library relies heavily on meta data in your Beancount file to find accounts and commodities. Please add these to your Beancount file:
### Commodities
If the commodity in your ledger differs from the symbol used by Wealthsimple, simply add `wealthsimple-symbol` as meta data:
```
2011-10-18 commodity ACWVETF
wealthsimple-symbol: "ACWV"
```
### Accounts
For Wealthsimple accounts themselves, you need to add this metadata: `importer-type: "wealthsimple"` and `number: "XXX"`. If the account can hold more than one commodity (all accounts except chequing and saving), it needs to follow this structure: `Assets:X:Y:Z:CashAccountName`, `Assets:X:Y:Z:CommodityName`, `Assets:X:Y:Z:OtherCommodityName`. The name of the cash account does not matter, but all other account must end with the commodity symbol (see above). Add the `importer-type` and `number` only to the cash account.
For accounts used in transactions to and from your Wealthsimple accounts you need to provide meta data as well. These is in the form of `wealthsimple-key: "accountNumber1 accountNumber2"`. The account number is the same as above, and you can specify one or multiple per key. As keys use these values:
* For dividend income accounts `wealthsimple-dividend-COMMODITYSYMBOL`, e.g. `wealthsimple-dividend-XGRO`
* For the assset account you are using to contribute to registered accounts from, use `wealthsimple-contribution`
* For the assset account you are using to deposit to non-registered accounts from, use `wealthsimple-deposit`
* Use `wealthsimple-fee` on an expense account to track the wealthsimple fees
* Use `wealthsimple-non-resident-withholding-tax` on an expense account for non resident withholding tax
* In case some transaction does not balance within your ledger, an expense account with `wealthsimple-rounding` will get the difference
* If you want to track contribution room, use `wealthsimple-contribution-room` on an asset and expense account (optional, if not set it will not create postings for the contribution room)
* Other values for transaction types you might incur are:
* `wealthsimple-reimbursement`
* `wealthsimple-interest`
* `wealthsimple-withdrawal`
* `wealthsimple-payment-transfer-in`
* `wealthsimple-payment-transfer-out`
* `wealthsimple-transfer-in`
* `wealthsimple-transfer-out`
* `wealthsimple-referral-bonus`
* `wealthsimple-giveaway-bonus`
* `wealthsimple-refund`
* `wealthsimple-payment-spend` (optional, will use fallback account if not provided)
Full Example
```
2020-07-31 open Assets:Checking:Wealthsimple CAD
importer-type: "wealthsimple"
number: "A001"
2020-07-31 open Assets:Investment:Wealthsimple:TFSA:Parking CAD
importer-type: "wealthsimple"
number: "B002"
2020-07-31 open Assets:Investment:Wealthsimple:TFSA:ACWV ACWV
2020-07-31 open Assets:Investment:Wealthsimple:TFSA:XGRO XGRO
2020-07-31 open Income:Capital:Dividend:ACWV USD
wealthsimple-dividend-ACWV: "A001 B002"
2020-07-31 open Assets:Checking:Bank CAD
wealthsimple-contribution: "A001 B002"
2020-07-31 open Expenses:FinancialInstitutions:Investment:NonRegistered:Fees
wealthsimple-fee: "A001"
2020-07-31 open Expenses:FinancialInstitutions:Investment:Registered:Fees
wealthsimple-fee: "B002"
2020-07-31 open Expenses:Tax:NRWT
wealthsimple-non-resident-withholding-tax: "A001 B002"
2020-07-31 open Assets:TFSAContributionRoom TFSA.ROOM
wealthsimple-contribution-room: "B002"
2020-07-31 open Expenses:TFSAContributionRoom TFSA.ROOM
wealthsimple-contribution-room: "B002"
````
## How
1) First create an instance of the mapper via `WealthsimpleLedgerMapper(ledger:)`, passing the ledger which contains the meta data discussed above.
2) Assign the downloaded wealthsimple accounts to the `accounts` property on the mapper.
3) Call `mapPositionsToPriceAndBalance` or `mapTransactionsToPriceAndTransactions` to map your downloaded positions / transactions to SwiftBeanCountModel Prices and Balances / Prices and Transactions.
Please also check out the complete documentation [here](https://nef10.github.io/SwiftBeanCountWealthsimpleMapper/). Additionally, you can have a look at the [SwiftBeanCountImporter](https://github.com/Nef10/SwiftBeanCountImporter) which uses this library.
## Usage
The library supports the Swift Package Manger, so simply add a dependency in your `Package.swift`:
```
.package(url: "https://github.com/Nef10/SwiftBeanCountWealthsimpleMapper.git", .upToNextMajor(from: "X.Y.Z")),
```
## Limitations
Please note that I developed this library for my own needs and there may be bugs. It currently has some limitations:
* Sell Gains are not calculated
* In case a transactions does not balance it will not add a rounding posting because SwiftBeanCountModel does not yet fully supporting Beancount rounding
Pull requests to extend the scope or remove limitations are very welcome.
