### Portfolio Data Refresh Sequence Flow

Source: https://github.com/streocalibration/divflow_1/blob/main/doc/architecture/diagrams/sequence_refresh.md

This Mermaid sequence diagram visualizes the end-to-end data refresh process in a portfolio management application. It illustrates the interaction flow starting from a user's refresh action, through the main window, application logic, price fetching service, and portfolio data management, culminating in the UI update.

```Mermaid
sequenceDiagram
    participant User
    participant MainWindow
    participant PortfolioApp
    participant PriceFetcher
    participant Portfolio

    User->>MainWindow: onRefreshClicked()
    MainWindow->>PortfolioApp: refreshData()
    PortfolioApp->>PriceFetcher: fetchAll()
    PriceFetcher-->>PortfolioApp: prices
    PortfolioApp->>Portfolio: updatePrices(prices)
    PortfolioApp->>Portfolio: calculateStats()
    PortfolioApp-->>MainWindow: updatedData
    MainWindow->>MainWindow: updateUI()
```

### Desktop Application Architecture Flowchart

A Mermaid flowchart illustrating the components of the desktop application, including the Desktop App (UI, Logic), Local Storage (JSON/SQLite), and External API (Price Data Service), and their data flows.

```Mermaid
flowchart TB
  subgraph Desktop_App ["Desktop App"]
    UI["UI (tkinter/Qt)"]
    Logic["PortfolioApp Logic"]
  end

  subgraph Local_Storage ["Local Storage"]
    DB["JSON / SQLite"]
  end

  subgraph External_API ["External API"]
    API["Price Data Service"]
  end

  Desktop_App --> Local_Storage
  Desktop_App --> External_API
```

### Portfolio Management Application Class Diagram

Source: https://github.com/streocalibration/divflow_1/blob/main/doc/architecture/diagrams/class_diagram.md

This snippet provides a structured API documentation representation of the core classes and their interactions within the portfolio management application, derived from the Mermaid class diagram. It details attributes, methods, and relationships for each component.

```APIDOC
PortfolioApp:
  - portfolio: Portfolio
  - priceFetcher: PriceFetcher
  - storage: PortfolioStorage
  - ui: MainWindow
  + refreshData(): void
  + saveState(): void
  + loadState(): void
  + calculateRebalancing(amount: float): void

Portfolio:
  - assets: List<Asset>
  + addAsset(asset: Asset): void
  + removeAsset(ticker: str): void
  + getTotalValue(): float
  + getAllocationRatios(): Map<str, float>
  + updatePrices(prices: Map<str, float>): void
  + calculateStats(): Map<str, any>

Asset:
  - ticker: str
  - weight: float
  - shares: float
  - avgCost: float
  - closePrice: float
  - dividendYield: float
  + getValue(): float
  + getGain(): float
  + getDividendAmount(): float
  + getWeightPercentage(total: float): float

PriceFetcher:
  + fetchClosePrice(ticker: str): float
  + fetchDividend(ticker: str): float
  + fetchAll(tickers: List<str>): Map<str, float>

PortfolioStorage:
  + save(portfolio: Portfolio): void
  + load(): Portfolio

MainWindow:
  - tableWidget: Widget
  - inputPanel: Widget
  - refreshButton: Button
  - rebalancingInput: InputField
  + updateUI(): void
  + onRefreshClicked(): void
  + onSaveClicked(): void
  + onAddFundClicked(): void

Relationships:
  PortfolioApp uses Portfolio
  PortfolioApp uses PriceFetcher
  PortfolioApp uses PortfolioStorage
  PortfolioApp uses MainWindow
  Portfolio contains multiple Assets
```

### Mermaid Flowchart for Divflow 1 User Interactions

Source: https://github.com/streocalibration/divflow_1/blob/main/doc/architecture/diagrams/use_case.md

Defines the main user-driven functionalities of the streocalibration/divflow_1 project, including adding assets, refreshing portfolios, rebalancing, and saving/loading application state, visualized as a Mermaid flowchart.

```Mermaid

  %% 액터
  User((User))

  %% 유스케이스
  A1((Add Asset))
  A2((Refresh Portfolio))
  A3((Rebalance with Deposit))
  A4((Save/Load State))

  %% 관계
  User --> A1
  User --> A2
  User --> A3
  User --> A4
