🏦 Scalable Capital Importers

broker_scalable and broker_scalable_deposit import the two accounts of Scalable Capital, each into a LibreFolio broker of its own: the broker account (Scalable Capital broker) and the overnight account (Scalable Capital overnight account). They live in backend/app/services/brim_providers/broker_scalable/plugin.py and broker_scalable_deposit/plugin.py (plugin_version 1.0.0, .csv only, detection_priority 100), which hold only their properties and calls to the shared reader, _scalable.py: recognition, refusals and parsing are written once, for both accounts. The leading underscore keeps _scalable.py out of the registry's auto-discovery.

This page covers what is specific to Scalable. The user's view is Scalable Capital, where the docs_url of both plugins points.

🗂️ Files and detection

Every file starts with the 14 columns of Scalable's own CSV export (PRIME_COLUMNS):

date;time;status;reference;description;assetType;type;isin;shares;price;amount;fee;tax;currency
File Header Read by
Scalable's own CSV — PRIME and PRIME+ plans, broker account only the 14 columns broker_scalable
The LibreFolio exporter's broker file the 14 columns, then lf_*; lf_account is broker broker_scalable
The exporter's overnight account file the 14 columns, then lf_*; lf_account is deposit broker_scalable_deposit
  • Recognition (read_file, behind can_parse): a .csv whose first line holds the 14 columns, in any case and any order, split on the delimiter the base class detects. Without an lf_account column the file is Scalable's own CSV, always the broker account; with it, the lf_account values give the account — broker, deposit, both (mixed), or none for an export without rows, which both plugins accept. The file name is never read: the user may rename the file. A file that cannot be read is simply not a Scalable export: recognition never raises.
  • Refusals (refusal): each plugin refuses the other account's file, and both refuse a mixed one, with a code and — except for the mixed file — the plugin that reads it. The codes are listed in Saying why with a code. Any other file gets no refusal.
  • Values are read by column name. The 14 columns use the decimal comma (to_decimal_it) and date is YYYY-MM-DD. Of the exporter's own columns, described in its format, the reader uses lf_account, lf_id, lf_subtype, lf_is_cancellation, lf_ordered_shares and lf_account_index.

📝 What is imported

_Reader takes the data rows in file order. A reversal (lf_is_cancellation is true) and a row whose status is not Executed or Settled are left out, and so is a row without a readable date, amount or currency. Then type, compared lower-case, decides:

In the file (type) Imported as
Buy, Savings plan BUY on the gross amount — the value of the shares, as Scalable's CSV and exporter 1.0.1 or later write it — with fee as a FEE and a positive tax as a TAX of the same asset. A negative tax, given back, becomes a DEPOSIT without asset
Sell SELL, the same way
a type containing Distribution DIVIDEND, gross — amount plus the tax withheld in tax — with that tax as a TAX of the same asset; net when tax is empty
Interest INTEREST, gross, with the tax withheld as a TAX, both without asset; net when tax is empty
Deposit, Withdrawal — bank transfers, and transfers between the two accounts DEPOSIT, WITHDRAWAL
Fee FEE, without asset
Taxes, Tax TAX, without asset; a positive amount, a refund, becomes a DEPOSIT
Any other row whose assetType is Cash, such as a bonus DEPOSIT or WITHDRAWAL, by the sign of amount
Security transfer, Corporate action and any other type Not imported: the scalable_not_imported notice lists them
  • Signs: a cash row whose sign contradicts its type — a negative Deposit, a positive Withdrawal or Fee — is booked by its sign, and so is a negative dividend or interest (scalable_cash_by_sign). A cash row, a dividend or an interest of zero is not imported (scalable_not_imported).
  • Trades without their details: in an exporter file, an empty fee means the details were not read, and the trade is booked on amount as it is, without legs (scalable_fees_unknown).
  • Exporter 1.0.0 is not supported: its trades carry the fee and the tax inside amount (added on a purchase, taken away on a sale), so both would be counted twice; the user exports again with 1.0.1 or later.
  • Only executed rows are imported. A Pending row with lf_ordered_shares and some shares already executed is an order filled in part (scalable_open_partial): it comes, executed, with a later export. The other statuses go to scalable_not_executed.
  • Assets: one fake asset id per ISIN — per description when the row has no ISIN — counting down from FAKE_ASSET_ID_BASE in order of first use, with extracted_isin and extracted_name (description) and no symbol; only the assets of written transactions are returned. The user matches them to LibreFolio's assets in the wizard's Review step. A trade or a dividend with neither ISIN nor description is unreadable.
  • Descriptions (_description): an optional leg prefix — Order fee, Tax, Tax refund — then the row's description (its type when empty, Scalable Capital when both are) cut to 350 characters, then id <lf_id> in exporter files and ref <reference> when the row has one, joined by ·. The id keeps two identical movements of one day apart and lets a new export recognise the rows already imported: the deduplication makes a match on the key fields LIKELY, unticked, only when the descriptions match too. Only the exporter's descriptions carry id …, so a row imported from one layout comes back from the other as a POSSIBLE duplicate, ticked.
  • Transfers between the two accounts (lf_subtype CASH_TRANSFER_IN or CASH_TRANSFER_OUT) are imported as plain DEPOSIT and WITHDRAWAL and listed by scalable_internal_transfers: a CASH_TRANSFER links two brokers, so the user merges the two halves in the bulk editor (Transfers). A merged half still matches when it is exported again (Merged transfers and exchanges).
  • Tags: import and scalable (_TAGS), from both plugins, so the two halves of a merged transfer carry the same tags. Both plugins declare history_tag scalable to match: broker_scalable by default, broker_scalable_deposit by override, since its default would be scalable_deposit.
  • Amounts are copied from the file, never recomputed or converted — a gross dividend or interest is the sum of amount and the tax withheld — and the currency comes from each row's currency: a value that is not an ISO 4217 code makes the row unreadable.

🔔 Notices

_NOTICES holds the eleven notices in display order, each with its severity, an English message and the comment of its evidence table. A notice comes only when it has rows, with context.count and one BRIMEvidence: those rows under the file's header, with their line numbers and an empty title, so the wizard captions the table itself. The wizard words the message as importWizard.brimNotice.<code> and the comment as importWizard.brimEvidence.<code>, keys present in the four catalogues; the English texts are the fallback (Talking to the import wizard).

Code Severity Rows
scalable_unreadable_rows warning A date, an amount, a currency, the shares or the security missing or unreadable: not imported
scalable_fees_unknown warning Exporter rows without their fee and tax details: imported on the amount shown, without legs
scalable_open_partial warning Orders filled in part and still open: not imported yet
scalable_reversal warning Reversals of a transaction already booked: not imported
scalable_not_imported warning Security transfers, corporate actions, other types and zero amounts
scalable_several_overnight_accounts warning The first row of each overnight account (lf_account_index), when the file holds more than one: they all go into one broker
scalable_not_executed info Pending, cancelled, expired or rejected rows
scalable_internal_transfers info Transfers between the two accounts: imported, to be merged
scalable_dividends_net info Dividends without tax: imported net
scalable_tax_refund info Tax refunds: imported as DEPOSIT
scalable_cash_by_sign info Cash rows of an unknown type, or with an unexpected sign: booked by the sign of amount

🧪 Samples and tests

  • backend/app/services/brim_providers/sample_reports/ holds scalable-prime-export.csv (Scalable's own CSV), scalable-broker-export.csv and scalable-deposit-export.csv (exporter 1.0.1, one file per account, whose internal transfers mirror each other): invented values on the real layout, described in the folder's README.md.
  • ./dev.py test external brim-scalable (test_external/test_brim_scalable.py) pins recognition, refusals, the three samples row by row, the rules on synthetic files and the catalogue keys; ./dev.py test api brim-scalable (test_api/test_brim_scalable_api.py) imports both accounts end to end, merges the transfers and imports them again as duplicates.
