Fix WebSocket hang and add EGX sector-based stock grouping

[Copilot]

Changes

WebSocket timeout fix

The get_hist while True receive loop had no timeout on the underlying WebSocket connection, causing the process to hang forever if TradingView stopped sending data without closing the connection (network stall, invalid symbol, etc.).

• _vendor/main.py: Added timeout=60 parameter to TvDatafeed.__init__; passed as timeout=self.timeout to create_connection(), so ws.recv() raises WebSocketTimeoutException instead of blocking indefinitely
• core.py: All four TvDatafeedLive(...) call sites now pass timeout=self.config.connection_timeout, wiring FetcherConfig.connection_timeout (default: 60s) down to the socket layer

# Before — no timeout, hangs forever on a stalled connection
self.ws = create_connection(
    "wss://data.tradingview.com/socket.io/websocket", headers=self.headers
)

# After — raises WebSocketTimeoutException after connection_timeout seconds
self.ws = create_connection(
    "wss://data.tradingview.com/socket.io/websocket", headers=self.headers, timeout=self.timeout
)

EGX sector grouping & browsing

Stocks can now be grouped by sector and fetched as a unit. Sector data is built in for the Egyptian Exchange (EGX).

• tradeglob/markets/egx.py: 15 EGX sectors with correctly classified stock tickers (Banking, Real Estate & Housing, Telecommunications, Food & Beverages, Construction & Building Materials, Healthcare & Pharmaceuticals, Petroleum & Energy, Financial Services & Investment, Insurance, Tourism & Hotels, Industrial & Manufacturing, Transportation & Logistics, Chemicals & Petrochemicals, Textile & Garments, Technology). Standalone helpers list_egx_sectors() and get_egx_sector_stocks() are provided.
• tradeglob/markets/__init__.py: New markets package.
• core.py: Three new methods on TradeGlobFetcher:
  • list_sectors(exchange) — list available sectors for an exchange
  • get_sector_stocks(sector, exchange) — return the ticker list for a sector
  • get_sector(sector, exchange, interval, start, end, ...) — fetch OHLCV data for every stock in a sector in one call, reusing the existing parallel get_multiple() engine
• tradeglob/__init__.py: Exports EGX_SECTORS, list_egx_sectors, get_egx_sector_stocks at the package level.
• examples/example_5_egx_sectors.py: End-to-end usage example.

# List all EGX sectors
sectors = fetcher.list_sectors('EGX')

# Browse stocks in a sector
banking_stocks = fetcher.get_sector_stocks("Banking", "EGX")
# → ['COMI', 'EGAL', 'ADIB', ...]

# Fetch closing prices for an entire sector
df = fetcher.get_sector(
    "Banking", "EGX", "Daily",
    start=date(2024, 1, 1),
    end=date(2024, 12, 31),
)

@copilot but my request was make more effecient approach but sectoring the stocks grouping them and get the related group. also add a feature in the EGX tap where users can open a list of sectors and pick a sector to view all its stocks

Done. Here's what was added:

tradeglob/markets/egx.py — 15 EGX sectors with their stock tickers (Banking, Real Estate & Housing, Telecommunications, Food & Beverages, Construction & Building Materials, Healthcare & Pharmaceuticals, Petroleum & Energy, Financial Services & Investment, Insurance, Tourism & Hotels, Industrial & Manufacturing, Transportation & Logistics, Chemicals & Petrochemicals, Textile & Garments, Technology).

Three new methods on TradeGlobFetcher:

# List all EGX sectors
sectors = fetcher.list_sectors('EGX')

# Get the stocks in a sector
banking_stocks = fetcher.get_sector_stocks("Banking", "EGX")
# → ['COMI', 'EGAL', 'ADIB', ...]

# Fetch OHLCV data for an entire sector in one call
df = fetcher.get_sector(
    "Banking", "EGX", "Daily",
    start=date(2024, 1, 1),
    end=date(2024, 12, 31),
)

get_sector() reuses the existing parallel get_multiple() engine, so fetching a whole sector is as fast as fetching any other stock list.

The standalone helpers list_egx_sectors(), get_egx_sector_stocks(), and EGX_SECTORS are also importable directly from tradeglob. A full usage example is in examples/example_5_egx_sectors.py.
