License

New Tea Quant License Applies to version 0.6.0 and later. 

Copyright holder: Garnet Xin

This file is the license for New Tea Quant (NTQ) from version 0.6.0 onward. It is not the Apache License. Do not call it Apache-2.0 or Apache License 2.0.

1. Non-commercial use

Personal learning, personal research, academic use, and a person running backtests or scans for their own account are non-commercial.

For non-commercial use only, the terms of the Apache License, Version 2.0 reproduced below apply. Where those terms say "the License", read them as this non-commercial grant, not as a grant of commercial use.

2. Commercial use

Commercial use needs a separate written license from the copyright holder before that use starts. Commercial use includes a company or other organization using the software in its business, and offering the software or a service built on it to others for a fee.

Ask for that license at https://new-tea.cn/zh-hans/contact

3. Website and hosted services

This license covers the software only. It does not grant an account, a quota, data, or any right to new-tea.cn or its successor. The website's own terms and the credential a caller holds decide whether a call is accepted.

The clients that call new-tea.cn are the module core/modules/ntq_external. Before any commercial use, remove that module. A later written commercial license applies this duty unless that license says otherwise. Tests and docs that exist only for that module go with it.

The module contains:

  • conf/endpoints.py — the member-AI, feedback, and usage-report URLs, and the contact-page URL shown by the feedback client
  • ai/ — member AI. When a membership token is present, chat and the quota request go to the website. The token file stays at userspace/system/membership/membership_token.txt. core/infra/membership/ only reads and writes that file. It does not call the website
  • feedback/ — a thumbs rating and optional short text posted to the website
  • track/ — registers the usage-report URL with core/infra/trace. Install reports are sent without a separate usage-stats choice. core/infra/trace does not contain the website URL. After this module is removed, Trace.track does not send

After the module is removed, the assistant uses only a key configured by the user. Strategy, tag, and install code may still call Trace.track. That call does not reach the website.

The UI is a separate bundle. Removing the module does not remove pages. Before commercial use, also remove or replace the screens that offer these hosted services: membership, feedback, and usage stats in settings; the feedback prompt; and the member-register link in the assistant. Then rebuild core/ui/fed. The bundle in core/ui/fed/build/ repeats those screens and is not a second source.

3.1 Links that are not clients

The files below only open pages. Commercial use does not require every such string to be deleted. It does require that your product not send its users to these pages as its registration, support, contact, or data-download channel, and that it not present itself as official NTQ.

  • core/ui/fed/src/views/appNav/appNav.js Contact link https://new-tea.cn/zh-hans/contact?from=ntq_app.
  • core/ui/fed/src/pages/welcomePage/welcomePage.js Documentation links under https://new-tea.cn/zh-hans/.
  • README.md and README_en.md Member download, contact, and tutorial links. The larger data pack is not downloaded by code; those files tell the user to fetch it from the member page.
  • docs/README.md
  • core/modules/assistant/context/know_how/configure_ai_key.md

There is no other built-in client in this repository that calls new-tea.cn. If you add one, it is covered by this section.

4. Research tool, not an investment decision

NTQ is a strategy research tool. It does not decide, recommend, or advise any investment. Nothing the software shows — a scan, a backtest, a report, a score, or a chart — is an investment decision or an offer to buy or sell any security, futures contract, fund, or other financial product.

Every strategy shipped with NTQ is a demonstration. Every dataset shipped with NTQ, including the demo pack and any sample series, is a demonstration. They show how the tool works. They are not a suggestion to trade, and they are not a promise of any result.

You alone decide whether to invest, what to invest in, and when. The copyright holder and contributors are not responsible for any investment action you take, or for any gain or loss that follows, even if you used NTQ while making that decision.

5. Usage reports

NTQ may send anonymous usage reports to the copyright holder's service. They show how the tool is used and where it fails, so the software can be improved. They are not an investment decision, and they are not a record of what you trade.

Reports of how you use the software are sent only after you agree. You can turn them off at any time. Turning them off stops later reports of that kind and drops reports still waiting on the machine. A launch setting on that machine can force reports on or off. The default is off until you agree, except for the install report below.

The install report is sent while NTQ is being installed, including when you have not been asked yet, and including when you later decline. It exists so a failed install can still be seen.

NTQ does not collect strategy source, parameter text, scan or backtest detail, universe contents, positions, orders, or trade records. It does not collect your name, email, account, password, token, API key, IP address, or hostname. A report may still carry the name of a strategy or tag you ran, and the text of a CLI run command, as described below.

Each report may include an anonymous installation id created on that machine, the operating system, CPU architecture, Python version, NTQ version, CPU count, memory size, disk type, and database engine.

5.1 Install

  • time spent on the install and on each step, and which steps were skipped
  • whether the install succeeded
  • a failure class, the exception type, and a shortened failure message with home and project paths removed
  • names of tables that failed to import

5.2 After you agree

  • which entry started the app: the UI, the user CLI, or the dev CLI. A strategy or tag run on the user CLI may include the command line
  • that you turned usage reports on or off, and where you did that
  • that a strategy or tag run finished: its key, its mode, whether it succeeded, elapsed time, how many entities it covered, and a performance shape such as job count, parallelism, time share across stages, or capital-utilization percentages. Not the profit or loss, and not the strategy contents
  • how often you open parts of the UI, such as which entry you use. This version does not send it. When it is added, this section still applies
  • errors the software itself raises. This version does not send them. When they are added, this section still applies

The client that sends these reports is listed in section 3.3.

6. Earlier versions

Copies of versions through 0.5.x that were already distributed under the Apache License 2.0 stay under that license. This file does not take those grants back.

The Apache License, Version 2.0, follows. It applies only to the non-commercial grant in section 1 above.

                             Apache License
