## What is Stock Mastery?

Practice with virtual cash in Stock Mastery. Stocks/guides are free; Pro unlocks new futures/options positions.

No deposits, broker connections or real orders. Apple bills Pro. Portfolios stay local, currencies stay separate and no app account is needed.

Free stock practice
• Taiwan: TWSE/TPEx end-of-day data, indices, breadth, rankings, valuation metrics, corporate-action dates and watchlists
• Taiwan paper fills at displayed closing or custom prices, plus pending limit orders
• U.S.: daily closes for all US-listed stocks/ETFs (public Nasdaq.com pages, can be turned off), virtual USD, fills at the close or your price
• U.S. holdings valued at the latest close; no real-time quotes or U.S. limit orders
• iPhone/iPad Taiwan background updates, controlled in Settings; iOS chooses timing/frequency, with no daily guarantee

Stock Mastery Pro: futures and options practice
• Taiwan TX, MTX, TMF, TE electronics and TF financial futures
• Micro S&P 500 (MES), Nasdaq-100 (MNQ), gold (MGC) and WTI crude oil (MCL) futures
• TXO calls/puts and standard U.S. stock/ETF options with 100 shares per contract
• Long/short positions, adding, partial/full closes and record export
• Enter practice expiry dates, strikes, fill prices, margin and fees
• For Taiwan positions, explicitly select a TAIFEX monthly/weekly contract to track its regular-session last traded price after the session, with source dates
• Overseas reference prices remain manual
• Separate virtual TWD/USD accounts share a real-time or custom practice clock

Tracking updates reference prices, not fills. Custom time pauses updates; they stop after practice expiry. Manual marks, adding or partial closes return the position to manual mode. Missing quotes retain the previous price/date; there is no settlement-price substitution or automatic contract rollover. Your expiry remains a practice setting; check the month and weekly series.

Advancing time does not load historical quotes, predict prices or change prices, cash or option time value. After trading, time cannot move backwards. Expired positions close manually.

Practice contracts are user-defined; entered prices are not executable quotes. No live options chain, exchange settlement, margin calls, forced liquidation, exercise, assignment or delivery. Adjusted U.S. contracts and U.S. index options are excluded. Futures require positive prices. Losses can exceed margin. Fees use your inputs and exclude transaction taxes.

Pro subscription
U.S. prices: US$0.99/month or US$9.99/year, billed annually in one payment. Both plans offer the same access. The App Store shows local prices before purchase. Subscriptions renew automatically unless cancelled before the current period ends. Manage or cancel through your Apple Account; Restore Purchases is in the Pro screen.

Member Center shows the plan, access expiry and workspace entry. Free previews never buy or open positions. Pro is required for new derivatives positions; records, reference-price updates, closing and export remain available after access ends. Clearing local data does not cancel subscriptions.

Learn and personalize
Guides cover finance terms, ETFs, risk, scams and Taiwan securities qualifications. Choose System Default or 12 app languages: Traditional Chinese, Simplified Chinese, English, Japanese, Korean, Spanish, French, German, Brazilian Portuguese, Indonesian, Hindi and Arabic. Optional reminders run Monday-Friday at 6 PM device-local time, including holidays; they are not price/fill alerts. Widgets show Taiwan summaries and daily knowledge on a system schedule.

Data is end-of-day, may be delayed/incomplete and is not executable. No historical charts. Taiwan limit fills use later daily ranges, not trade replay. Legacy U.S. pending orders can only be cancelled. No personalized advice or guaranteed returns.

### 2.5.0 — 2026-10-17

• App languages now include Traditional Chinese, Simplified Chinese, English, Japanese, Korean, Spanish, French, German, Brazilian Portuguese, Indonesian, Hindi and Arabic. Switch in Settings or follow the system.
• Added iPhone/iPad background updates for Taiwan market data, controlled in Settings > Automatic Market Updates. iOS decides when and how often updates run; fixed daily updates are not guaranteed. Check the source dates.

Manual marks, adding or partial closes return the position to manual mode. Fill prices remain entered by you; no automatic rollover or settlement.

Stock practice stays free. Pro remains required for new derivatives positions; management, closing and export remain available after access ends. U.S. stocks and overseas derivatives use manual prices. All trades use virtual cash, without live quotes, historical replay, real orders, automatic settlement, exercise, assignment or physical delivery.

### 2.4.0 — 2026-10-13

• Paper Trading is now laid out like a brokerage account page: switch between the Taiwan, U.S. and Futures & Options (Pro) accounts, see market value, total cost, P/L (excl. dividends) and available cash in one statement card, plus a new allocation ring.
• Holdings, pending orders and history are now tabs. Each holding shows total shares and P/L; expand it for average cost, price, value and day change, with View Stock and Order actions.
• The order ticket is a brokerage-style form: Buy/Sell buttons, odd lot or round lot, order-type chips, price and share steppers that follow Taiwan tick sizes, Quote / Holding / Funds reference panels and the estimated amount in the bottom bar.
• Watchlist adds a quote-tile view and a Holdings tab; Profile adds a shortcut grid.
• Futures and options still require Pro to open positions. Colors and typography are unchanged.

Stock practice stays free. Taiwan uses end-of-day data; U.S. stocks use offline custom prices. Derivatives use user-defined contracts, prices and margin, without live quotes, historical replay, real orders, automatic settlement, exercise, assignment or physical delivery.

• Track long/short positions, partial closes, manual reference prices and P&L in separate virtual accounts.
• Add Restore Purchases and subscription management. Existing records, closing and export remain available after Pro access ends.
• Fix stock selection/navigation and improve input validation, order estimates and local account recovery. Language preferences remain available and saved in Settings.

Stock practice stays free. Taiwan uses end-of-day data; U.S. stocks use offline custom prices. Pro prices and billing periods appear before purchase.
