Which sources the guides and free calculators on fincodelabs.com are based on, how they are checked, when they are updated and how errors are corrected.

Last updated: November 5, 2026

## 1. Purpose and scope

Fincode Yazılım ve Teknoloji A.Ş. ("Fincode") publishes guides in Turkish on funds, stocks, markets, personal finance and algorithmic trading, guides in English on trading software, exchange APIs and money and investing in Turkey, and free calculators in both languages on fincodelabs.com. This content is general information. It is not prepared with any person's finances, risk preferences or legal situation in mind, and it does not replace investment, legal or tax advice.

## 2. Sources

Guides rely first on primary and official sources: Turkey's Capital Markets Board (SPK), the Central Bank of the Republic of Türkiye (TCMB), the Turkish Statistical Institute (TÜİK), the Revenue Administration (GİB), the Official Gazette (Resmî Gazete) and mevzuat.gov.tr, Borsa Istanbul, the Public Disclosure Platform (KAP), the Central Registry Agency (MKK), Takasbank, the Banking Regulation and Supervision Agency (BDDK), the Social Security Institution (SGK) and the official documents of other public bodies; on technical topics, the official documentation of exchanges and software providers, and peer-reviewed academic work. News sites are used only when no official source exists. Every guide ends with a list of the sources it used.

## 3. Dated information

Information that can change, such as rates, limits, amounts, trading hours and rules, is given with the date from which it applies. Each guide shows its publication date at the top and, if it was updated later, the update date. Figures that cannot be verified are not published. No forecast is made for data that has not been announced yet (for example, an increase that has not been declared); only the calculation method and the announcement timetable are explained.

## 4. Preparation and checks

Every guide goes through a separate checking stage before it is published: its claims are compared with their sources, source links are opened and verified, numerical examples and tables are recalculated, and language and terms are reviewed for consistency. Unless stated otherwise, numerical examples in the guides are hypothetical and are labeled as such. The formulas and default values of the calculators are tested; the result a calculator gives for the example must be exactly the same as the worked example on its page.

## 5. Updates and corrections

When rules, rates or data change, the guides concerned are updated and the update date is shown at the top of the guide. If you notice an error, write to [info@fincodelabs.com](mailto:info@fincodelabs.com?subject=Correction%20report); including the address of the page and the information that looks wrong speeds up the check. Errors that are confirmed are corrected.

## 6. Independence and promotion

Fincode is a software development company. It does not provide investment advice, portfolio management, brokerage or crypto asset services. The guides do not recommend any particular stock, fund, crypto asset, bank or brokerage firm. Fiva is a product developed by Fincode; below the guides are boxes that present a related Fiva feature, one of Fincode's services or a calculator. In the text of a guide, Fiva is mentioned only where it is directly relevant, and then as Fincode's own product. No paid or sponsored content is published on the site.

## 7. Project pages

In the [examples](https://fincodelabs.com/en/projects) section, Fiva is described as Fincode's own product. The other project pages are not real client projects. They are example scenarios that show the approach Fincode takes in this kind of work, and each of these pages says so clearly.
