Simulation System

• 琉星羽模拟系统 v3.280.exe — main program (runtime included; just double-click, no dependencies to install)
• 使用说明.txt — this document
• v3.280_交付清单.md — itemised contents of this release

Since v3.280 the configuration is embedded in the program, so the package no longer ships a separate config file. Personalisation (theme, interface, fee rates, watchlist and so on) is adjusted on the in-app “Settings” page; changes take effect at once and are saved automatically.

Program settings and security policy are built in. Please do not edit the program files by hand — doing so may stop the program from starting or make verification fail.

Upgrading from an older version: the data directory is now %APPDATA%\琉星羽模拟系统\. On first launch the old directory (股票交易指令系统) is migrated automatically, and holdings, trades, alerts, journal and login state are all preserved.

1. Double-click 琉星羽模拟系统 v3.280.exe to launch. The program starts a local service on this machine only (127.0.0.1) and never exposes it to the internet; the desktop window opens automatically.

2. Core features (quotes, F10, holdings, trading, portfolios, journal, settings) need no login — guest mode can use them.

3. The quant workbench is a paid extra: sign in and pass membership verification first (see “Accounts and membership”).

4. If antivirus software raises a false alarm, whitelist this folder and try again — this is a common false positive for PyInstaller builds, not a virus.

5. Open “Help / Shortcuts” inside the program for the full shortcut list; the command palette jumps quickly between features.

Where: the account area on the right of the top bar (it reads “Not signed in”, or shows your avatar and name once you are) → drop-down menu.

“Account centre” shows your account details and membership status (activation date, expiry date, days remaining), and lets you change the password and manage signed-in devices.

1. Register and sign in: create the administrator on first use; registration uses a local captcha and rate limiting. Your account and password are kept on this machine only and are never uploaded.

2. Becoming a member: click “Quant” → the “Unlock membership” window opens → enter your activation code → it unlocks once the online check passes.

3. How membership is verified:

• Membership takes effect once the cloud check passes, so a working connection is needed while you use it;
• After verification a credential bound to this device is stored locally, so the quant workbench keeps working through a temporary network outage; once the offline period ends you need to go online again. Changing device or reinstalling the system requires re-verification;
• Membership is verified inside the program, so editing the program files from outside cannot unlock or extend it. When membership expires, the quant workbench closes again as a non-member feature.

4. My sessions: view the list of signed-in devices (tokens masked, “this device” marked) and sign out of the current or other devices.

5. Forgot your password: ask the administrator to reset it.

6. Safety note: this system does not connect to any broker and never places real orders.

• 8 dashboard styles (Settings → Dashboard style): Jinhong UI, Aurora, Black Hole, Hero, Workbench, Classic, Ink Landscape, Agent Workbench (default).
• Light and dark: the moon/sun button in the nav bar, or the settings page (Black Hole and Agent Workbench are dark-only, so the toggle hides itself there).
• Accent colour: several presets to choose from, or set your own. Text scaling has four steps.
• Three motion levels (Gentle / Standard / Lively), switched on the settings page or in the motion lab; the spring strength applies across the app immediately.
• Low-spec mode (Settings → Performance): one click reduces blur and animation; if the system has “reduce transparency” or “reduce motion” enabled, the program

adopts the same reduced mode automatically.

• Always on top: Settings → Always on top, toggled directly through Win32.

1. Workbench (default home)

Three columns: session list, conversation and inspector. The “rule explainer” does exactly two things: it explains rules you set yourself, and explains public accounting terms and figures. It does not evaluate any security, does not forecast, and gives no buy or sell opinion. The top bar switches to the dashboard.

• Sessions: create, rename, delete, switch; messages persist with their session;
• Endpoints: add, edit, delete and activate (OpenAI-protocol compatible); the active endpoint is what the assistant uses;
• Alert records: ignore a single one, or clear all ignores; run-log entries and price alerts can be deleted one by one or cleared.

2. Dashboard

Index strip, asset overview (animated total), alert summary, watchlist, allocation ring and a rebalance calculator showing the gap against target weights you set. The dashboard presents only what you entered plus public market data, and makes no value judgements.

3. Market data

Under the “Market” menu: All A-shares, conditional filtering (filters public data by PE / PB / market cap / change using criteria you set — filtering only, no ranking and no recommendations), industry sectors, watchlist heatmap, ETF, industry valuation, Dragon-Tiger list, global markets, commodities. Data sources: Eastmoney primary, Tencent and Sina as fallback. Quotes carry a market timestamp; anything delayed by more than 2 minutes is marked in orange.

4. Stock detail and F10

Click a holdings row to open the detail drawer on the right: candlesticks, intraday, order book, capital flow, valuation, financials, news, fetch quotes and memos. The “F10 company profile” button at the top of the drawer (or the F10 key) jumps straight to F10.

F10: 22 tabs in 7 groups (company, financials, chips, trading, valuation, events, announcements). The content is publicly disclosed information and company announcements, with sources credited. Hovering a chart picks the whole column and reads out the values; “Enlarge” expands it in place to near full screen. Tables use zebra striping with a pinned first column.

5. Holdings and records

Under the “My” menu: holdings, add a stock, action log, portfolio overview, portfolio templates, portfolio history and activity log.

When you add a stock you enter two alert levels yourself: below_price and above_price. The software never presets or suggests a price.

6. Price alerts and recording rules

• When the live price reaches the below_price or above_price you set: a top banner, a dot in the status bar and a run-log entry — three reminders at once;
• An alert means only that the level you set has been reached. It carries no buy or sell opinion; whether and how to act is entirely your call;
• Colour semantics: red for up and green for down (the A-share convention); below your lower alert level is green, above your upper alert level is red;
• The alert ladder raises one reminder per percentage band you set: it only records and reminds, and never generates an order instruction.

7. Backtest explainer · teaching demo (members only, “Quant” menu)

1. Guide: illustrated explanations of what backtesting is, why overfitting happens and why out-of-sample testing matters — so you form a correct understanding of “historical statistics”.

2. Terms explained: the meaning and calculation of publicly defined measures such as β, volatility and VaR (published textbook material), for your own understanding only — the software outputs no such figures for any instrument.

3. Data self-check: one click confirms that live quotes are retrievable (source, bar count, range, last price, volume unit and elapsed time).

4. “View documentation” opens a structured Chinese reference (backtest principles, overfitting and out-of-sample testing, metric definitions, data sources and risk notes).

Teaching note: this module covers published backtest knowledge only — it demonstrates no strategy, compares no parameters, draws no conclusions and computes no measures for any instrument. It does not represent future performance, is not investment advice and must not be used as a basis for decisions.

8. Journal

“My → Journal”: notes and reviews (date, title, mood, body), automatically appended with that day's actions and alert triggers; browsed by month, editable, and deleted with two-step confirmation.

9. Data and backup

“Data” menu: back up, or back up to the desktop; import and export JSON, and export CSV, alert records, the action log and the rebalancing list.

Adjust personal settings (theme, interface, fee rates, watchlist and so on) on the in-app “Settings” page — changes take effect at once and there is no need to edit files by hand.

• Fees: commission, stamp duty and transfer fee, used for trading costs and position cost calculations.
• Watchlist and monitoring: the watchlist, ETF premium/discount monitoring and alert conditions.
• Appearance: several colour schemes, light and dark, motion and text size.
• Program settings and security policy are built in and will not be weakened by outside edits.
• A fresh install generates default settings on first launch; upgrading migrates your existing settings and data automatically.

• The interface still looks like the old version after an upgrade: quit the program completely first (right-click the tray icon and exit, or end the process in Task Manager), then start it again.

Static-asset caching has been disabled since v3.280, so this should not recur.

• If the interface is still wrong, delete the webview cache and restart (your account, holdings and settings are unaffected):

%LOCALAPPDATA%\琉星羽模拟系统\EBWebView

• “Membership verification failed” in the quant module: first click “Test connection” in the membership dialog to check the network. If the cloud is temporarily unreachable, the offline credential keeps working until it expires; once it has expired, restore the network and sign in again to re-verify.
• Asked to sign in every time: check that the program's folder is writable, because login state has to be written to disk. If it is installed in a read-only folder, reinstall into a writable one — the program will move its data to your user folder automatically.

• Always-on-top misbehaving: turn “Settings → Always on top” off and on again.

Simply delete this folder — no registry entries are left behind. The database and runtime data live in %APPDATA%\琉星羽模拟系统\; delete that directory as well for a complete wipe.

This software is an “investment instruction aid”: it provides quote viewing, position records and price alerts only. It does not constitute investment advice and never executes trades on its own. Every buy and sell decision is yours to make.

It does not provide securities investment advisory or discretionary management services, does not recommend any security and does not give buy or sell advice. Every alert level and condition is entered by the user; the software only compares prices and raises reminders.

Investing carries risk — enter the market with care. This platform provides information and analytical support only and does not constitute professional investment advice; users bear the risk of their own decisions and any resulting gains or losses, and the platform is not liable for any investment outcome.

Quantitative backtests are simulations on historical data, for study and reference only; backtested returns do not represent future performance.
