Why exists Grafioschtrader (GT)

For a few years I used a portfolio management application that met my initial needs. Over time, I realized that transaction and custody costs have a significant impact on the overall return of the portfolio. So I looked for different online stockbrokers that offered the most favorable trading conditions for my investment. So far, only a combination of several trading platforms has met my needs. As a Swiss investor, there is also the fact that sooner or later investments are made in foreign currencies.

Over time, you lose track of how much is invested in what. I thought this didn’t have to be the case and, as a software developer, I plunged into the Grafioschtrader adventure. With GT I now have an overview of the positions held, performance and account balances per portfolio or cumulated across all portfolios.

What can GT

• The software is free and open source: GT is released as open source and can be found on GitHub.
• Multi-tenancy: GT can be run for a group of investors or in single mode.
• Web application: GT is a web application and provides the clearest results using a desktop web browser.
• Multiple portfolios with currency accounts: Replicates multiple portfolios with one or more securities accounts and one or more bank cash accounts.
• Multiple currencies: Trading securities in different currencies
• Trading from the turn of the millennium: Basic support for historical price data from the year 2000 onwards, noting that obtaining price data from non-traded securities may be a problem.
• Different financial instruments: Stocks, Bonds, ETF, securities without price data, short ETF, CFD, Forex.
• Import of transactions: An import of single or multiple PDFs with securities transactions Via CSV file, account transactions can also be loaded.
• Evaluations by asset classes: Evaluations by common asset classes such as stocks, bonds, real estate, commodities, etc.

For whom is suitable GT

GT is an attempt to replicate portfolios according to reality, so there are accounts just like with your online stockbroker. Each booking is linked to a cash account, so the bookings are replicated according to your trading platform.

• The investor who does not want to entrust his financial data to a non-transparent platform. You can host GT yourself, all you need is a Raspberry Pi 4 with 4GB (possibly 2GB) of RAM.
• A shareholder who wants to have a history of all his trades. You can view all closed positions at any time.
• Private investors who want to know how their currency profits are developing. The currency gains on the foreign currency accounts are shown on an ongoing basis.
• Investors’ club who want to host their own GT instance and would like a member to take care of the technical aspects.
• Investors with several portfolios on different trading platforms. GT provides information per portfolio and can display it in aggregated form.

For whom GT is not made

Before you waste your lifetime unnecessarily with GT, you should consider the following:

• Day traders lack real-time quotes.
• Investors who want to manage their trading independently of cash accounts.
• Investors who only have one portfolio with an online broker and are satisfied with the analyses provided there.
• There are investors who create portfolios according to certain criteria, such as a dividend portfolio. GT does not support such an approach. On the contrary, the aggregated evaluation of real portfolios on different trading platforms is the goal.
• In GT there is no support for alleged real public portfolios of users. The developers of GT cannot make sense of these possible fake portfolios. Most importantly, a portfolio is individual and hopefully strongly influenced by the circumstances of the respective investor. Reducing this to a few numbers and graphs is nothing more than disinformation.

For whom GT does not work

GT is definitely not a jack of all trades:

• For investors who want to manage transactions with GT before the year 2000. GT consistently implements double-digit annual figures.
• In GT, the combination of ISIN and currency of an instrument is unique. It is therefore not possible to enter the same ETF in EUR for the Frankfurt and Stuttgart stock exchane, for example.
• For investors who want to assign an instrument to a sector/topic and country/region at the same time.
• For investors from Switzerland, Germany or the USA who require a security number, securities identification number (WKN) or CUSIP number. GT uses the International Securities Identification Number (ISIN) and the ticker/symbols, which are not always unique.
