…cs-keyerror

fix: KeyError in trade_metrics_table.py (#352)

Adds a new CCXTTickerDataProvider that handles DataType.TICKER data
sources using CCXT's fetch_ticker API. This resolves the 'No data
provider found' error when strategies request ticker data.

Changes:
- New CCXTTickerDataProvider class in infrastructure/data_providers/ccxt.py
- Registered as default data provider alongside CCXTOHLCVDataProvider
- Exported from all package __init__.py levels
- 15 unit tests with mocked CCXT calls

Closes #350

Replace the CI-only skip with a fully mocked CCXT exchange so the
download test reads from local CSV data in tests/resources/test_data/ohlcv
instead of making network calls.

feat: add CCXTTickerDataProvider for TICKER data sources (#350)

…han data timeframe (#396)

- Add validation in TradingStrategy.__init__ that compares the strategy's
  scheduling interval (time_unit * interval) against the smallest OHLCV
  data source timeframe. Raises OperationalException with a descriptive
  message if the interval is too fast.
- Add 7 tests in tests/app/test_strategy_interval_validation.py covering
  all edge cases (faster, equal, slower, multiple sources, no sources,
  non-OHLCV sources, error message content).
- Fix test strategies in test_data_completeness.py that had invalid
  1-minute intervals with 1-day OHLCV data.

… by ~3x (#397)

Bug 1: In create_order_metadata_with_trade_context, the cost variable
accumulated across loop iterations but the entire accumulated value was
subtracted from each trade's revenue. With N trades, earlier costs were
subtracted N times instead of once, systematically understating net_gain.
Fix: use per-iteration trade_cost variable.

Bug 2: In _create_trade_metadata_with_sell_order_and_trades, net_gain
used sell_amount (total sell order) instead of trade_data['amount']
(per-trade portion), overcounting gain per trade when a sell order
was split across multiple trades. Fix: use trade_data['amount'].

Added 3 regression tests in tests/services/test_trade_service_net_gain.py.

…ests (#331)

- Add CSVTickerDataProvider class for ticker data from CSV files
- Export CSVTickerDataProvider at all package levels
- Add 19 new tests for CSVOHLCVDataProvider (has_data, get_data,
  backtest, edge cases, symbol/market/timeframe matching)
- Add 7 new tests for CSVTickerDataProvider (loading, has_data,
  get_data, symbol/market/data_type matching, custom identifier)
- Add new test data CSV files for backtesting scenarios
- Fix test_trade_price_update to use proper data fixtures

…Is (#334)

- tasks.md: Replace fabricated examples with real Task class (time_unit/interval)
  and @app.task() decorator usage
- trades.md: Document actual Trade model attributes (opened_at, open_price,
  net_gain) and Context methods (get_trade, get_open_trades, add_stop_loss, etc.)
- deployment.md: Replace generic Docker/VPS content with real CLI commands
  (iaf init, iaf deploy-aws-lambda, iaf deploy-azure-function)
- Fix bug in app.py add_strategy() using non-existent worker_id instead of strategy_id
- Uncomment and fix 2 eventloop tests (test_initialize, test_get_data_sources_for_iteration)
- Update BacktestTradeOrderEvaluator constructor for new required params

Closes #334

- Fix prism-react-renderer import for Docusaurus 3.x compatibility
- Fix sidebar.js: replace missing doc IDs with actual files (data-sources, backtest_data)
- tasks.md: add class-level attribute pattern alongside constructor pattern
- Add show_docs.sh script for running docs locally (with --build option)
