# Broker Portfolio Display Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Улучшить страницу брокерского счета: разделить позиции акций и облигаций, добавить текущую цену, сделать инструменты кликабельными и оформить операции с русскими типами, бейджами эффекта и cursor-пагинацией по 10 строк.

**Architecture:** Изолировать правила отображения в `brokerDisplay.ts`, чтобы маршруты инструментов, русские labels и impact-классификация тестировались отдельно от React. Вынести таблицы позиций и операций в небольшие компоненты рядом со страницей брокера, а `BrokerAccountDetailPage.tsx` оставить контейнером данных и состояния пагинации.

**Tech Stack:** React 18, react-router-dom v6 `Link`, TanStack Query через существующие hooks, Vitest, Testing Library, TypeScript.

## File Structure

- Create: `apps/frontend/src/pages/broker/brokerDisplay.ts`
  - Pure helper functions for grouping positions, building instrument links, mapping operation labels and classifying operation impact.
- Create: `apps/frontend/src/pages/broker/brokerDisplay.test.ts`
  - Unit tests for all display helpers.
- Create: `apps/frontend/src/pages/broker/BrokerPositionsSection.tsx`
  - Presentational component for `Акции`, `Облигации`, and `Другие инструменты` tables.
- Create: `apps/frontend/src/pages/broker/BrokerOperationsTable.tsx`
  - Presentational component for operations table, impact badges, linked instruments and pagination controls.
- Modify: `apps/frontend/src/pages/broker/BrokerAccountDetailPage.tsx`
  - Replace inline tables with the two components and add cursor stack state for operations.
- Modify: `apps/frontend/src/pages/broker/BrokerPages.test.tsx`
  - Page-level tests for positions, operations links, Russian labels and pagination behavior.

## Task 2: Broker Position Tables

**Files:**

- Create: `apps/frontend/src/pages/broker/BrokerPositionsSection.tsx`
- Modify: `apps/frontend/src/pages/broker/BrokerAccountDetailPage.tsx`
- Modify: `apps/frontend/src/pages/broker/BrokerPages.test.tsx`

- [ ] **Step 1: Add failing page test for split position tables**

Append this test to `apps/frontend/src/pages/broker/BrokerPages.test.tsx` inside `describe('Broker pages', () => { ... })`:

```tsx
it('renders broker positions as separate linked stock and bond tables with current price', () => {
  vi.spyOn(portfolioHook, 'useBrokerPortfolio').mockReturnValue({

  expect(screen.getByRole('heading', { name: 'Облигации' })).toBeInTheDocument();
  expect(screen.queryByRole('columnheader', { name: 'Доходность' })).not.toBeInTheDocument();
  expect(screen.getAllByRole('columnheader', { name: 'Цена' })).toHaveLength(2);

  );
  expect(screen.getByText(/250,00/)).toBeInTheDocument();
  expect(screen.getByText(/900,00/)).toBeInTheDocument();

```

- [ ] **Step 2: Run page test and verify failure**

Run:

```bash
npx vitest run src/pages/broker/BrokerPages.test.tsx -w apps/frontend
```

Expected: FAIL because the current page renders one `Позиции` table, has `Доходность`, and does not link tickers.

- [ ] **Step 3: Create the positions component**

Create `apps/frontend/src/pages/broker/BrokerPositionsSection.tsx`:

import { useParams } from 'react-router-dom';
import type { BrokerMoney } from '../../api/responses';
import { useBrokerOperations } from '../../hooks/useBrokerOperations';
import { useBrokerPortfolio } from '../../hooks/useBrokerPortfolio';
import { BrokerPositionsSection } from './BrokerPositionsSection';
```

Replace the entire current `<section>` with heading `Позиции` and its inline table with:

```tsx
<BrokerPositionsSection positions={portfolio.data.positions} />
```

Remove `tableStyle`, `thStyle` and `tdStyle` from `BrokerAccountDetailPage.tsx` after the inline
positions table is deleted. These constants move into the table components and must not remain unused.

- [ ] **Step 5: Run page test and verify success**

Run:

```bash
npx vitest run src/pages/broker/BrokerPages.test.tsx -w apps/frontend
```

Expected: PASS for the new split positions test and existing broker page tests.

- [ ] **Step 6: Commit position table changes**

Run:

```bash
git add apps/frontend/src/pages/broker/BrokerPositionsSection.tsx apps/frontend/src/pages/broker/BrokerAccountDetailPage.tsx apps/frontend/src/pages/broker/BrokerPages.test.tsx
git commit -m "feat: split broker position tables"
```

Expected: commit succeeds.

## Task 3: Broker Operations Table and Cursor Pagination

**Files:**

- Create: `apps/frontend/src/pages/broker/BrokerOperationsTable.tsx`
- Modify: `apps/frontend/src/pages/broker/BrokerAccountDetailPage.tsx`
- Modify: `apps/frontend/src/pages/broker/BrokerPages.test.tsx`

- [ ] **Step 1: Add failing test for operation labels, links and impact badges**

Append this test to `apps/frontend/src/pages/broker/BrokerPages.test.tsx`:

```tsx
it('renders broker operations with Russian labels, linked instruments and impact badges', () => {
  vi.spyOn(portfolioHook, 'useBrokerPortfolio').mockReturnValue({
    data: {
      account: {
        id: 'acc-1',

```

- [ ] **Step 2: Add failing test for cursor pagination**

Add import at the top of `BrokerPages.test.tsx`:

```tsx
import userEvent from '@testing-library/user-event';
```

Append this test to `apps/frontend/src/pages/broker/BrokerPages.test.tsx`:

```tsx
it('requests broker operations by cursor with a page size of 10', async () => {
  const user = userEvent.setup();
  vi.spyOn(portfolioHook, 'useBrokerPortfolio').mockReturnValue({

        openedAt: null,
        accessLevel: null,
      },
      totals: { portfolio: { currency: 'RUB', units: '10000', nano: 0, value: 10000 } },
      yields: { expectedPercent: null, daily: null, dailyPercent: null },
      cash: [],
      blockedCash: [],
      positions: [],
      asOf: '2026-06-17T00:00:00.000Z',
    },
    isLoading: false,
    error: null,
  } as any);
  const operationsSpy = vi.spyOn(operationsHook, 'useBrokerOperations').mockImplementation(

        isLoading: false,
        error: null,
      }) as any,
  );

  renderWithClient(
    <Routes>
      <Route path="/broker/:accountId" element={<BrokerAccountDetailPage />} />
    </Routes>,
    ['/broker/acc-1'],
  );

  expect(operationsSpy).toHaveBeenLastCalledWith('acc-1', { limit: 10, cursor: undefined });
  expect(screen.getByText('Страница 1')).toBeInTheDocument();

  await user.click(screen.getByRole('button', { name: 'Вперед' }));

  expect(operationsSpy).toHaveBeenLastCalledWith('acc-1', {
    limit: 10,
    cursor: 'cursor-page-2',
  });
  expect(screen.getByText('Страница 2')).toBeInTheDocument();

  await user.click(screen.getByRole('button', { name: 'Назад' }));

  expect(operationsSpy).toHaveBeenLastCalledWith('acc-1', { limit: 10, cursor: undefined });
  expect(screen.getByText('Страница 1')).toBeInTheDocument();
});
```

- [ ] **Step 3: Run page tests and verify failure**

Run:

```bash
npx vitest run src/pages/broker/BrokerPages.test.tsx -w apps/frontend
```

Expected: FAIL because operations still render raw enum values and `BrokerAccountDetailPage` calls `useBrokerOperations(accountId, { limit: 100 })`.

- [ ] **Step 4: Create the operations table component**

Create `apps/frontend/src/pages/broker/BrokerOperationsTable.tsx`:

```tsx
import { Link } from 'react-router-dom';
import type { BrokerMoney, BrokerOperation, BrokerOperationsPage } from '../../api/responses';
import {
  getBrokerInstrumentPath,
  getBrokerOperationImpact,
  getBrokerOperationImpactLabel,
  getBrokerOperationTypeLabel,
  type BrokerOperationImpact,
} from './brokerDisplay';

const tableStyle = {
  width: '100%',
  borderCollapse: 'collapse',
  fontSize: 14,
} satisfies React.CSSProperties;

const thStyle = {
  borderBottom: '1px solid #e0e0e0',

} satisfies React.CSSProperties;

const tdStyle = {
  borderBottom: '1px solid #eeeeee',
  padding: '10px 8px',
  verticalAlign: 'top',
} satisfies React.CSSProperties;

const impactStyles: Record<BrokerOperationImpact, React.CSSProperties> = {
  adds: {
    background: 'rgba(46, 125, 50, 0.1)',
    color: 'var(--color-positive)',
  },
  reduces: {
    background: 'rgba(198, 40, 40, 0.1)',
    color: 'var(--color-negative)',
  },
  neutral: {
    background: 'rgba(25, 118, 210, 0.1)',
    color: 'var(--color-primary)',

    color: 'var(--color-text-secondary)',
  },
};

function formatMoney(value: BrokerMoney | null | undefined) {
  if (!value) return '-';

  return new Intl.NumberFormat('ru-RU', {

    currency: value.currency || 'RUB',
    maximumFractionDigits: 2,

}

function formatDate(value: string | null) {
  if (!value) return '-';

  return new Date(value).toLocaleString('ru-RU');
}

function moneyColor(impact: BrokerOperationImpact): string {
  if (impact === 'adds') return 'var(--color-positive)';
  if (impact === 'reduces') return 'var(--color-negative)';
  return 'var(--color-text)';
}

function OperationInstrument({ operation }: { operation: BrokerOperation }) {
  const label = operation.ticker || operation.description || '-';
  const path = getBrokerInstrumentPath({
    ticker: operation.ticker,
    instrumentType: operation.instrumentType,
    classCode: operation.classCode,
  });

  if (!path || label === '-') {
    return <span>{label}</span>;
  }

  return <Link to={path}>{label}</Link>;
}

function OperationType({ operation }: { operation: BrokerOperation }) {
  const impact = getBrokerOperationImpact(operation);

  return (
    <div style={{ display: 'grid', gap: 4 }}>
      <span>{getBrokerOperationTypeLabel(operation)}</span>
      <span
        style={{
          justifySelf: 'start',
          borderRadius: 999,
          fontSize: 12,
          fontWeight: 700,
          lineHeight: 1,
          padding: '5px 8px',
          ...impactStyles[impact],
        }}
      >
        {getBrokerOperationImpactLabel(impact)}

          </table>
        </div>
      )}
    </section>
  );
}
```

- [ ] **Step 5: Add cursor pagination state to the page**

Modify `apps/frontend/src/pages/broker/BrokerAccountDetailPage.tsx`.

Update imports:

```tsx
import { useState } from 'react';
import { useParams } from 'react-router-dom';
import type { BrokerMoney } from '../../api/responses';
import { useBrokerOperations } from '../../hooks/useBrokerOperations';
import { useBrokerPortfolio } from '../../hooks/useBrokerPortfolio';
import { BrokerOperationsTable } from './BrokerOperationsTable';
import { BrokerPositionsSection } from './BrokerPositionsSection';
```

Inside `BrokerAccountDetailPage`, before calling `useBrokerOperations`, add:

```tsx
const [operationCursor, setOperationCursor] = useState<string | undefined>(undefined);
const [operationCursorStack, setOperationCursorStack] = useState<Array<string | undefined>>([]);
```

Replace the existing operations hook call:

```tsx
const operations = useBrokerOperations(accountId, {
  limit: 10,
  cursor: operationCursor,
});
```

Add handlers after error/loading guards or before `return`:

```tsx
function handleNextOperationsPage() {
  const nextCursor = operations.data?.nextCursor;
  if (!nextCursor || !operations.data?.hasNext) return;

  setOperationCursorStack((previous) => [...previous, operationCursor]);
  setOperationCursor(nextCursor);
}

function handlePreviousOperationsPage() {
  if (operationCursorStack.length === 0) return;

  const nextStack = operationCursorStack.slice(0, -1);
  const previousCursor = operationCursorStack[operationCursorStack.length - 1];
  setOperationCursorStack(nextStack);
  setOperationCursor(previousCursor);
}
```

Remove `formatDate` from `BrokerAccountDetailPage.tsx` after the inline operations table is deleted.
Date formatting now belongs to `BrokerOperationsTable.tsx`.

Replace the current inline operations `<section>` with:

```tsx
<BrokerOperationsTable
  isLoading={operations.isLoading}
  page={operations.data}
  pageNumber={operationCursorStack.length + 1}
  canGoBack={operationCursorStack.length > 0}
  canGoForward={Boolean(operations.data?.hasNext && operations.data.nextCursor)}
  onPrevious={handlePreviousOperationsPage}
  onNext={handleNextOperationsPage}
/>
```

- [ ] **Step 6: Run page tests and verify success**

Run:

```bash
npx vitest run src/pages/broker/BrokerPages.test.tsx -w apps/frontend
```

Expected: PASS for operation labels, links, impact badges and pagination tests.

- [ ] **Step 7: Commit operations table changes**

Run:

```bash
git add apps/frontend/src/pages/broker/BrokerOperationsTable.tsx apps/frontend/src/pages/broker/BrokerAccountDetailPage.tsx apps/frontend/src/pages/broker/BrokerPages.test.tsx
git commit -m "feat: improve broker operations table"
```

Expected: commit succeeds.

## Task 4: Regression Verification

**Files:**

- No source file changes in this task.

- [ ] **Step 1: Run focused frontend tests**

Run:

```bash
npx vitest run src/pages/broker/brokerDisplay.test.ts src/pages/broker/BrokerPages.test.tsx -w apps/frontend
```

Expected: PASS for helper and broker page tests.

- [ ] **Step 2: Run the full frontend test suite**

Run:

```bash
npm run test:frontend
```

Expected: PASS for the frontend Vitest suite.

- [ ] **Step 3: Run frontend build**

Run:

```bash
npm run build:frontend
```

Expected: TypeScript build and Vite build complete successfully.

- [ ] **Step 4: Run lint**

Run:

```bash
npm run lint
```

Expected: ESLint completes without errors for backend and frontend workspaces.

- [ ] **Step 5: Commit verification-only adjustments if tests required small fixes**

If verification revealed small issues and the fixes are already applied, run:

```bash
git add apps/frontend/src/pages/broker
git commit -m "test: cover broker portfolio display"
```

Expected: commit succeeds when there are verification fixes. If there are no additional changes, this step is skipped.

## Task 5: Review Handoff

**Files:**

- No source file changes in this task.

- [ ] **Step 1: Summarize final diff**

Run:

```bash
git status --short
git log --oneline -3
```

Expected: working tree contains only intentional changes for this feature, and recent commits correspond to helpers, positions and operations.

- [ ] **Step 2: Request code review**

Use `superpowers:requesting-code-review` before merging or opening a PR. Ask the reviewer to focus on:

- cursor stack behavior when navigating back and forward;
- operation impact classification for trades, taxes, fees, coupons and transfers;
- accessibility of impact badges when color is not visible;
- whether helper tests cover unknown operation types and missing tickers.

- [ ] **Step 3: Choose execution mode for this plan**

Recommended execution mode: Subagent-Driven.

Subagent split:

- Subagent 1: Task 1 helpers and unit tests.
- Subagent 2: Task 2 positions component and page tests.
- Subagent 3: Task 3 operations component and pagination tests.
- Main agent: Task 4 verification and Task 5 review handoff.

Inline execution is also acceptable if branch state or local context makes subagent handoff less efficient.
