Six clear steps

Input doesn’t become an order right away

Each step requires you to understand and be in control before moving to the next.

  1. 01

    Input

    Gather your investing principles from notes, links, and documents.

  2. 02

    Interpret

    Turn conditions and exceptions into candidate executable rules.

  3. 03

    Clarify

    Ambiguous or conflicting criteria get asked back to you.

  4. 04

    Set risk limits

    Decide exposure limits, loss limits, and stop conditions first.

  5. 05

    Approve the strategy

    Review the final rules and any changes, then approve them yourself.

  6. 06

    Run on your PC

    API keys are stored and executed only on your own PC, never on the web.

My investing note

Only enter while the long-term trend is intact, and never buy all at once. Stop when volatility gets too high or the daily loss limit is hit.

Principles we keep before convenience

API keys stay on your PC

Stored in Windows Credential Manager.

Interpretation is not execution

An analysis result is a draft. It doesn’t run until it passes clarifying questions, risk limits, and your approval.

Your principles become executable rules

We structure the entry, exit, and risk limits you define into a verifiable strategy, then execute only what you approved—consistently and transparently.

Investment risk notice

Automated trading doesn’t remove the possibility of loss. Past performance doesn’t guarantee future results, and losses can occur from exchange, network, or program errors.
