Transitioning TradingSuite.create() to accept a list of instruments. - Updating component access from direct attributes (e.g., suite.data) to instrument-specific contexts (e.g., suite["MNQ"].data). - Ensuring all statistics-related calls are asynchronous and use the correct method names. - Correcting method signatures for order placement where necessary. --- docs/README.md | 11 +- docs/api/client.md | 12 +- docs/api/data-manager.md | 106 +++++---- docs/api/models.md | 71 +++--- docs/api/order-manager.md | 205 +++++++++-------- docs/api/position-manager.md | 140 ++++++++---- docs/api/risk-manager.md | 90 +++----- docs/api/statistics.md | 39 ++-- docs/api/trading-suite.md | 208 +++++++++--------- .../001_multi_instrument_suite_refactor.md | 2 +- docs/development/contributing.md | Bin 16474 -> 16476 bytes docs/examples/advanced.md | 42 ++-- docs/examples/basic.md | 52 +++-- docs/examples/multi-instrument.md | 12 +- docs/examples/notebooks/index.md | 6 +- docs/examples/realtime.md | 19 +- docs/getting-started/authentication.md | 4 +- docs/getting-started/configuration.md | 4 +- docs/getting-started/installation.md | 7 +- docs/guide/indicators.md | 57 ++--- docs/guide/orderbook.md | 20 +- docs/guide/orders.md | 4 +- docs/guide/positions.md | 10 +- docs/guide/trading-suite.md | 26 ++- docs/index.md | 2 +- 25 files changed, 635 insertions(+), 514 deletions(-) diff --git a/docs/README.md b/docs/README.md index 8bfc499..1eb28d4 100644 --- a/docs/README.md +++ b/docs/README.md @@ -119,8 +119,15 @@ Always use async/await patterns: ```python async def example(): -

This change brings the examples in line with the current multi-instrument API, ensuring they serve as accurate and up-to-date guides for users. Key changes include: - Replaced deprecated direct property access for `data`, `orders`, `positions`, `risk_manager`, and `orderbook` with the recommended instrument-based context access. - Updated method calls to reflect the latest asynchronous and dictionary-based API, such as for statistics and real-time data handling. - Corrected the use of instrument properties like `instrument_info` and `symbol`. - Removed redundant `suite.connect()` calls, as `TradingSuite.create()` now handles connections automatically. - Modernized the code by using enhanced model properties like `.direction` and `.side_str` for cleaner logic. --- .secrets.baseline | 4 +- examples/00_trading_suite_demo.py | 6 +- examples/02_order_management.py | 8 +- examples/03_position_management.py | 108 ++++++++------- examples/04_realtime_data.py | 2 +- examples/05_orderbook_analysis.py | 2 +- examples/06_advanced_orderbook.py | 6 +- examples/07_technical_indicators.py | 4 +- examples/08_order_and_position_tracking.py | 52 ++++---- examples/10_unified_event_system.py | 8 +- examples/11_simplified_data_access.py | 24 ++-- examples/12_simplified_multi_timeframe.py | 14 +- examples/13_simplified_strategy.py | 12 +- examples/14_enhanced_models.py | 10 +- examples/15_order_lifecycle_tracking.py | 67 ++++++---- examples/16_risk_management.py | 22 +-- examples/17_join_orders.py | 36 ++--- examples/18_managed_trades.py | 22 +-- examples/19_risk_manager_live_demo.py | 126 ++++++++---------- examples/20_statistics_usage.py | 18 ++- examples/25_dynamic_resource_limits.py | 24 ++-- examples/99_error_recovery_demo.py | 49 ++++--- .../00_eth_vs_rth_sessions_demo.py | 2 +- .../00_basic_multi_instrument_example.py | 108 +++++++++++++++ .../01_multi_instrument_optional_features.py | 44 ++++++ examples/advanced_dataframe_operations.py | 28 ++-- .../00_events_with_wait_for.py | 6 +- .../01_events_with_on.py | 22 +-- 28 files changed, 510 insertions(+), 324 deletions(-) create mode 100644 examples/Multi_Instrument_Trading_Suite/00_basic_multi_instrument_example.py create mode 100644 examples/Multi_Instrument_Trading_Suite/01_multi_instrument_optional_features.py diff --git a/.secrets.baseline b/.secrets.baseline index 2a5d82c..a04080b 100644 --- a/.secrets.baseline +++ b/.secrets.baseline @@ -203,7 +203,7 @@ "filename": "examples/17_join_orders.py", "hashed_secret": "11fa7c37d697f30e6aee828b4426a10f83ab2380", "is_verified": false, -
