Nendojo is a free tool for practising trading on real market history, and a set of guides built around that practice. The name joins nến, the Vietnamese word for candle, with dojo, a hall for practice.
What we believe
Reading about trading is not the same as doing it. Most guides show a finished chart, where every trade looks obvious. We would rather give you the chart one candle at a time and let you find out what you would really have done.
What you will not find here
- Promises of profit, or stories about how much someone made.
- Price predictions.
- Signal groups, trading bots or copy-trading offers.
- Pressure to sign up for anything.
How it is paid for
The app is free and carries no ads. The guides carry display ads. A few guides link to well-known exchanges with referral links, each one labelled. Readers can also donate. That is all.
Who makes it
Nendojo is built and maintained by an independent developer. The app’s source code is public under the AGPL-3.0 licence, so anyone can read exactly what it does.
How the guides are written
Guides are drafted with the help of AI. Prices, dates and percentages in them are computed from market data rather than recalled, and each guide is checked against that data before it is published. If you find a mistake, please tell us through the contact page.
