A complete, human-readable portfolio review (console and a self-contained HTML report with interactive, offline charts and analysis tables).
A Wealthfolio-compatible CSV so the same XTB history can be imported into the Wealthfolio portfolio tracker.
Portfolio Performance-compatible CSVs split into Portfolio Transactions and Account Transactions for import into Portfolio Performance.

The parser is generic for XTB exports in this format. Tests generate a small synthetic workbook at runtime, while personal brokerage exports should stay local and untracked.

Quick Start

Use the skills in your own agent

This is the recommended path if you want an LLM or coding agent to run the XTB workflows for you. Give your agent access to this repository and ask it to follow INSTALL_FOR_AGENTS.md. That file tells the agent how to install or use the portable skill folders, validate them, and run the right workflow for your XTB workbook.

Install the XTB agent skills:

npx skills add farcasclaudiu/xtb-investment-tools

Install prompt:

Read https://github.com/farcasclaudiu/xtb-investment-tools/blob/main/INSTALL_FOR_AGENTS.md and install the XTB skills for your agent harness.

Portfolio review prompt examples:

Use the XTB portfolio review skill to generate and verify a report for my XTB
workbook.

Use the XTB portfolio review skill to generate the HTML report, export the CSV
tables, and summarize the reconciliation status and data-quality caveats.

Use the XTB portfolio review skill with EUR_demo_report.xlsx as the input file.
Generate the review, run validation, and report the generated output paths.

Wealthfolio export prompt examples:

Use the XTB Wealthfolio export skill to create and validate a Wealthfolio CSV
from my XTB workbook.

Use the XTB Wealthfolio export skill to inspect the generated CSV rows and tell
me whether they are ready to import into Wealthfolio.

Use the XTB Wealthfolio export skill with EUR_demo_report.xlsx as the input file
and write the Wealthfolio CSV to results/EUR_demo_report_wealthfolio.csv.

Portfolio Performance export prompt examples:

Use the XTB Portfolio Performance export skill to create and validate CSV files
from my XTB workbook.

Use the XTB Portfolio Performance export skill and explain how to import the two
generated CSV files into Portfolio Performance.

Use the XTB Portfolio Performance export skill with EUR_demo_report.xlsx as the
input file and write the CSV files to results/.

Run the tools directly

From the repository root:

python3 -m venv .venv
.venv/bin/python -m pip install --upgrade pip
.venv/bin/python -m pip install -r requirements.txt

.venv/bin/python main.py path/to/xtb-report.xlsx
.venv/bin/python exporter.py path/to/xtb-report.xlsx
.venv/bin/python portfolio_performance_exporter.py path/to/xtb-report.xlsx

Outputs are written to results/, including results/<stem>_review.html and results/<stem>_summary.json for the portfolio review and results/<stem>_wealthfolio.csv for the Wealthfolio import file. The Portfolio Performance exporter writes results/<stem>_portfolio_performance_portfolio_transactions.csv and results/<stem>_portfolio_performance_account_transactions.csv. Pass the XTB workbook path explicitly for the portfolio review; use --auto-detect only when you intentionally want to process the single .xlsx in the current folder. Add --csv to the portfolio review command only when you want the extra per-section CSV exports.

Background: the XTB export format

An XTB report is an .xlsx file with a fixed layout:

Rows 1–4: metadata (account number, report period).
Row 5 (header=4): the actual column headers.
Sheets:
- Closed Positions — realized trades, with a Profit/Loss column. May contain a Profit/loss summary row and/or be empty (all positions still open).
- Cash Operations — every cash flow: stock purchases/sales, deposits, withdrawals, dividends, dividend tax, free-funds interest, currency conversions. Each trade row carries a comment like OPEN BUY 6 @ 301.50 or CLOSE SELL 2 @ 100.00, and the sheet ends with a Total row. That Total is the final cash left in the account, not the value of stocks or ETFs.

Two quirks the code handles explicitly:

Header is on row 5, not row 1.
Split-fill quantity notation: OPEN BUY 1/100 @ 14.3130 means 1 share out of a 100-share parent order — the numerator is the executed quantity. The tools use the numerator (falling back to cash / price) rather than mis-reading 1/100 as 0.01.
Stock-sale close notation: some XTB stock-sale rows are written as CLOSE BUY ... while the row type is Stock sell and the amount is positive sale proceeds. The tools treat these as sales for holdings, cash flows, and Wealthfolio and Portfolio Performance export.

Files

Source code

File	Purpose
`skills/xtb-portfolio-review/scripts/main.py`	Portfolio review generator. Parses the XTB report, reconstructs trades from Cash Operations comments, runs FIFO lot-matching for realized P/L, computes cash flows, holdings (cost basis), performance metrics, contribution/risk/income analysis, and reconciliation against the broker's `Total` row. Outputs a console report and a self-contained HTML report with interactive Chart.js charts and offline table tools (bundled inline, no internet required).
`skills/xtb-wealthfolio-export/scripts/exporter.py`	XTB -> Wealthfolio CSV exporter. Maps each Cash Operation to a Wealthfolio row (`date,symbol,quantity,activityType,unitPrice,currency,fee`).
`skills/xtb-portfolio-performance-export/scripts/exporter.py`	XTB -> Portfolio Performance CSV exporter. Splits XTB cash operations into Portfolio Transactions and Account Transactions CSV files.
`main.py`, `exporter.py`, `portfolio_performance_exporter.py`, `html_charts.py`	Thin compatibility entry points that preserve the original repo commands/imports while delegating to the bundled skill implementations.

Tests

File	Purpose
`test_portfolio.py`	Unit + integration tests for `main.py` (parsing, FIFO realized P/L, cash-flow categorization, income, open positions, performance, analysis helpers, reconciliation against the generated synthetic workbook, HTML structure and interactions).
`test_exporter.py`	Tests for `exporter.py` (activity-type classification, the split-fill quantity parser, full row mapping, schema validation on the generated synthetic workbook, empty-input handling).
`test_portfolio_performance_exporter.py`	Tests for `portfolio_performance_exporter.py` (two-file CSV export, semicolon schema, transaction separation, account labels, split fills, empty-input handling).

Local inputs

Personal .xlsx exports are not committed. Place your XTB report in the repo folder when running the tools locally, or pass its path explicitly.

Generated outputs (regenerated by running the tools)

All generated files are written to the results/ folder (created automatically) and named after the input report: for input EUR_demo_report.xlsx every output uses that stem plus a descriptor, e.g. EUR_demo_report_review.html.

File	Produced by	Content
`results/<stem>_review.html`	`main.py`	Self-contained HTML report with interactive Chart.js charts, analysis sections, sortable/filterable tables, sticky navigation, and print/PDF styles; works offline.
`results/<stem>_holdings.csv`	`main.py`	Open holdings: ticker, shares, avg cost, cost basis, return %, allocation %.
`results/<stem>_cash_flows.csv`	`main.py`	Aggregated cash flows (deposits, interest, dividends, invested, …).
`results/<stem>_realized_pl.csv`	`main.py`	Realized P/L per ticker.
`results/<stem>_open_positions.csv`	`main.py`	Live market value / unrealized P/L (when an `Open Positions` sheet exists).
`results/<stem>_performance.csv`	`main.py`	Performance metrics (portfolio value, returns, yield).
`results/<stem>_income.csv`	`main.py`	Income (dividends + interest) by month.
`results/<stem>_evolution.csv`	`main.py`	Daily cost / market value / realized P/L series (drives the evolution chart).
`results/<stem>_wealthfolio.csv`	`exporter.py`	Wealthfolio-importable transaction history.
`results/<stem>_portfolio_performance_portfolio_transactions.csv`	`portfolio_performance_exporter.py`	Portfolio Performance `Portfolio Transactions` import file for buys and sells.
`results/<stem>_portfolio_performance_account_transactions.csv`	`portfolio_performance_exporter.py`	Portfolio Performance `Account Transactions` import file for deposits, dividends, taxes, interest, fees, and transfers.

Setup

Requires Python 3.10+.

python3 -m venv .venv
.venv/bin/python -m pip install --upgrade pip
.venv/bin/python -m pip install -r requirements.txt

The HTML report bundles Chart.js v4.5.1 (vendored inside each relevant skill at scripts/assets/chartjs.umd.min.js, version pinned in scripts/assets/chartjs.VERSION) so its charts render interactively with no internet connection.

Agent skills

This repository includes harness-neutral agent skills under skills/ for users who want an LLM or coding agent to operate the tools consistently. Each skill is a self-contained folder with a SKILL.md, references/, and bundled scripts/, so users can copy a skill folder to another machine and still run the relevant XTB workflow without cloning the full repository.

Agents should start with INSTALL_FOR_AGENTS.md for copy/install/use instructions.

Skill	Purpose
`xtb-portfolio-review`	Generate and verify XTB portfolio review reports, including reconciliation, holdings, performance, income, risk, and data-quality caveats.
`xtb-wealthfolio-export`	Export and validate Wealthfolio-compatible CSV files from XTB reports, including activity mappings and import-readiness checks.
`xtb-portfolio-performance-export`	Export and validate Portfolio Performance-compatible CSV files from XTB reports, including import workflow instructions.

Use the skill folder directly, or copy it into the skill/instruction directory for your harness. With a generic LLM, ask it to read the relevant SKILL.md. For Codex, you can also copy either folder into ~/.codex/skills/, then invoke it in a new session:

Use $xtb-portfolio-review to generate and verify an XTB portfolio report.
Use $xtb-wealthfolio-export to create and validate a Wealthfolio CSV from an XTB report.
Use $xtb-portfolio-performance-export to create and validate Portfolio Performance CSV files from an XTB report.

Each copied skill folder includes scripts/requirements.txt plus shell wrappers for environment setup, validation, and execution. From the directory where you want .venv and results/ to live, install dependencies with:

skills/xtb-portfolio-review/scripts/setup-env.sh
skills/xtb-wealthfolio-export/scripts/setup-env.sh
skills/xtb-portfolio-performance-export/scripts/setup-env.sh

Usage

Generate the portfolio review

.venv/bin/python main.py EUR_demo_report.xlsx                     # explicit report
.venv/bin/python main.py EUR_demo_report.xlsx --csv               # also write the CSV outputs
.venv/bin/python main.py --auto-detect                            # intentionally use the only .xlsx in the folder

By default only the self-contained HTML report (with inline interactive charts and table tools) plus a bounded summary JSON are written to results/. Pass --csv to additionally export the per-section CSVs (holdings, cash flows, performance, …).

If no path is given, the portfolio review exits with a prompt to pass the path explicitly. --auto-detect keeps the older convenience behavior for local use: if exactly one .xlsx is present in the current directory, it is used; if there are none or several, pass the path explicitly. Any same-format XTB export works — the currency is auto-detected from the filename prefix (e.g. EUR_…, USD_…).

HTML report features

The generated review HTML is a single offline file. It includes:

Executive Summary — largest holding, top unrealized winner/loser, cash allocation, pricing warnings, and reconciliation status.
Concentration & Risk — top-1/top-3/top-5 position weights, cash weight, positions above 20%, and cost-priced position count.
Income Quality — gross income, dividend tax, net income, tax drag, net income yield, and dividend/interest mix.
Methodology & Data Quality — live-vs-cost pricing coverage, cost fallback tickers, reconciliation status, and the main calculation assumptions.
Return Contribution — per-ticker market value, unrealized P/L, realized P/L, total contribution, and contribution % of total gain.
Interactive charts — portfolio evolution, holdings allocation, cash flows, and income over time when data exists.
Offline table tools — data tables are sortable and filterable in the browser without any external JavaScript.
Navigation and print support — a sticky section nav for browsing and print/PDF styles for cleaner exported reports.

Export to Wealthfolio CSV

.venv/bin/python exporter.py                          # uses the default report -> results/<stem>_wealthfolio.csv
.venv/bin/python exporter.py EUR_other.xlsx -o my.csv  # explicit input/output

Export to Portfolio Performance CSV

.venv/bin/python portfolio_performance_exporter.py EUR_demo_report.xlsx
.venv/bin/python portfolio_performance_exporter.py EUR_demo_report.xlsx -o results
.venv/bin/python portfolio_performance_exporter.py EUR_demo_report.xlsx --securities-account "XTB" --cash-account "XTB (EUR)"

The exporter writes two UTF-8 semicolon-delimited files:

results/<stem>_portfolio_performance_portfolio_transactions.csv
results/<stem>_portfolio_performance_account_transactions.csv

Import them into Portfolio Performance in this order:

In Portfolio Performance, create or open the target portfolio file.
Ensure the Portfolio Performance Securities Account and Deposit Account exist, or use the importer's account selection step to create/select them. Defaults expected from the CSV are XTB and XTB (<CCY>).
Import results/<stem>_portfolio_performance_portfolio_transactions.csv first via File > Import > CSV files.
In the CSV wizard, select type Portfolio Transactions.
Use UTF-8, delimiter semicolon, and enable First line contains header.
Confirm mappings for Date, Type, Shares, Ticker Symbol, Security Name, Value, Fees, Taxes, Securities Account, and Cash Account. In the CSV importer, Cash Account maps to the Portfolio Performance deposit account.
Finish that import and resolve any security matching prompts before continuing.
Import results/<stem>_portfolio_performance_account_transactions.csv via File > Import > CSV files.
In the CSV wizard, select type Account Transactions.
Use the same CSV settings: UTF-8, semicolon delimiter, first line header.
Confirm mappings for Date, Type, Value, Ticker Symbol, Security Name, Shares, Gross Amount, Currency Gross Amount, Cash Account, and Offset Account. In the CSV importer, Cash Account maps to the Portfolio Performance deposit account.
Review Portfolio Performance's preview/status column before finishing, especially transfers, taxes, and dividends.

Portfolio transactions should usually be imported before account transactions so referenced securities exist before dividend rows are processed.

How the review is computed

Trades are reconstructed from the OPEN/CLOSE BUY/SELL … @ price comments in Cash Operations (the Closed Positions sheet is often empty for still-open accounts). Trades are keyed by the real Ticker column (e.g. SPYL.DE), so descriptive variants of the same instrument merge into a single holding. Trades are processed in chronological order — XTB sheets sometimes list a position's close leg before its open leg, so date-ordering is required for correct FIFO lot matching.
Holdings are the net open lots per ticker at cost basis, with allocation %.
Live market value is fetched via yfinance for the last trading day on/before the report's Date to. The close is taken in the symbol's native currency and converted to the account currency when needed. Any ticker that can't be priced (delisted / not on Yahoo) falls back to cost basis and is flagged price_source = "cost" in the holdings CSV and report.
Realized P/L prefers the broker's Closed Positions Profit/Loss column; when that is absent, it falls back to FIFO lot matching from CLOSE trades.
Cash flows are categorized (deposits, withdrawals, interest, dividends, dividend tax, FX fees, invested, proceeds). The report then checks whether its calculated ending cash matches XTB's Total row, which is the final cash left in the account.
Performance combines live market value (or cost basis fallback) with cash to give portfolio value, total gain, total return %, money-weighted return (XIRR), and income yield. XIRR uses external deposits/withdrawals plus terminal portfolio value; dividends and interest are not treated as external cash flows unless they leave the account as withdrawals.
Return contribution combines each open holding's unrealized P/L with any realized P/L by ticker, then expresses the result as a share of total gain.
Concentration & risk is derived from market-value weights, cash weight, and pricing source coverage; it flags large top holdings and cost-priced positions.
Income quality separates gross income, dividend tax, net income, tax drag, net income yield, and the dividend-vs-interest mix.
Evolution chart replays the trades chronologically and, for each trading day, computes the open cost basis, the open market value (from historical closes via yfinance, falling back to cost for unpriced tickers), and cumulative realized P/L. The gap between the Cost and Value (realized + unrealized) lines is the total investment gain/loss. Daily series is persisted to results/<stem>_evolution.csv when --csv is used.

Wealthfolio activity mapping

XTB operation	Wealthfolio `activityType`
`Stock purchase` / `OPEN BUY`	`BUY`
`Stock sale` / `CLOSE SELL` / `OPEN SELL` (short)	`SELL`
`Deposit` / `Withdrawal`	`DEPOSIT` / `WITHDRAWAL`
`Dividend`	`DIVIDEND`
`Free funds interest`	`INTEREST`
`Dividend tax`	`TAX`
`Currency conversion`	`FEE`

Per the Wealthfolio CSV spec, cash activities (DEPOSIT/WITHDRAWAL/DIVIDEND/INTEREST/TAX/FEE) carry their total value in the amount column with quantity = 1 and unitPrice = 1; the fee column is only used for inline BUY/SELL commissions. Pure-cash rows use the $CASH-<CCY> symbol (e.g. $CASH-EUR), while DIVIDEND keeps the security's real ticker. BUY/SELL leave amount blank — Wealthfolio auto-calculates it as quantity × unitPrice.

Portfolio Performance activity mapping

XTB operation	Portfolio Performance import row
`Stock purchase` / `OPEN BUY`	Portfolio `Buy`
`Stock sale` / `Stock sell` / `CLOSE SELL` / `OPEN SELL`	Portfolio `Sell`
`Stock sell` with `CLOSE BUY`	Portfolio `Sell`
`Deposit` / `Withdrawal`	Account `Deposit` / `Withdrawal`
`Dividend`	Account `Dividend`
`Free funds interest`	Account `Interest`
`Dividend tax` / `RO tax` / interest tax rows	Account `Taxes`
`Currency conversion`	Account `Fees`
`Subaccount transfer` / `Transfer`	Account `Transfer (Inbound/Outbound)`

The Portfolio Performance exporter follows the app's documented import split: use the Portfolio Transactions CSV for buys/sells and the Account Transactions CSV for cash movements, income, taxes, fees, and transfers.

Notes & limitations

Live prices are daily closes from yfinance, taken for the last trading day on or before the report's Date to. A symbol that can't be resolved (e.g. some proprietary XTB instrument codes) is valued at cost and flagged with price_source = "cost".
Cost fallback positions carry zero unrealized P/L in the report, contribution table, and evolution chart. The methodology section lists every cost fallback ticker.
Money-weighted return (XIRR) requires at least one external cash outflow and one inflow. When the dated cash-flow series cannot be solved, the report shows n/a.
Reconciliation checks whether the report's calculated ending cash matches XTB's Total row. This is a cash check only: it does not compare the full value of the portfolio. It reports [OK] when the two cash numbers match within €0.01.
HTML interactions (charts, sorting, filtering, sticky navigation) are all inline and offline; no CDN or network access is required to open the generated report.
Thousand-separators are intentionally not parsed in numeric fields (ambiguous with decimal dot); XTB's plain decimal format is handled correctly.
All generated artifacts go to results/ (git-ignored via .gitignore).
