About QuantKit, and who writes it.
QuantKit is a show-your-work desk for retail algorithmic traders. Every figure on this site carries its source, date and arithmetic — reproduce it from the page.
QuantKit is a one-person research desk for algorithmic traders. It publishes three things: tools that check whether a backtest is telling the truth, cost ledgers that measure what trading actually costs, and a free market data API for Asian symbols. Every number on the site carries its source, its date and the arithmetic that produced it, so a reader can rebuild the figure instead of trusting the author. When a figure is wrong, the correction is published in the corrections log rather than quietly edited. QuantKit sells tools, not advice. No credentials are claimed; the method is the credential.

Who writes this
Timoranjes builds, tests and documents trading systems in public. Cost figures, grades and corrections follow a fixed method and are not adjusted for partners. Disclosed referral relationships — when live — are named on /disclosure/.
The work is published under a pseudonym. The test is the work: each figure names its source and date and shows its arithmetic, so you can rebuild it without trusting the author.
How to check this site. Every figure links to its source, so you can rebuild it yourself.

What QuantKit is, and is not
The scope is narrow on purpose. It keeps every claim on the site checkable.
It is
- Dated, sourced broker cost figures, with the formula shown and the method written down.
- A free, delayed market-data endpoint for A-share, Hong Kong and US markets.
- Tools the author uses: spreadsheets, Python toolkits and prompt systems, sold on Gumroad.
- A public corrections log. Mistakes are logged, not quietly edited.
It is not
- A signal service. No trade signals, alerts or calls are sold or given.
- Advice. Nothing here is financial or investment advice.
- An undisclosed referral shop. Marked Referral links, when present, are named on /disclosure/. Payment does not buy inclusion, rank or softer wording.
- A track record. The strategy log is simulated and publishes no results.
How QuantKit is paid is set out in the disclosure. Questions or errors: [email protected].
