From bd6a0f05d773c57d69c69e816c2a2cee9a2b21af Mon Sep 17 00:00:00 2001 From: "Vasily.onl" Date: Mon, 26 May 2025 16:46:04 +0800 Subject: [PATCH] Implement Incremental BBRS Strategy for Real-time Data Processing - Introduced `BBRSIncrementalState` for real-time processing of the Bollinger Bands + RSI strategy, allowing minute-level data input and internal timeframe aggregation. - Added `TimeframeAggregator` class to handle real-time data aggregation to higher timeframes (15min, 1h, etc.). - Updated `README_BBRS.md` to document the new incremental strategy, including key features and usage examples. - Created comprehensive tests to validate the incremental strategy against the original implementation, ensuring signal accuracy and performance consistency. - Enhanced error handling and logging for better monitoring during real-time processing. - Updated `TODO.md` to reflect the completion of the incremental BBRS strategy implementation. --- cycles/Analysis/bb_rsi.py | 3 +- cycles/IncStrategies/README_BBRS.md | 329 ++++++++++++++ cycles/IncStrategies/TODO.md | 114 ++++- cycles/IncStrategies/bbrs_incremental.py | 532 +++++++++++++++++++++++ cycles/IncStrategies/indicators/rsi.py | 87 ++-- test/debug_rsi_differences.py | 112 +++++ test/test_bbrs_incremental.py | 289 ++++++++++++ test/test_incremental_indicators.py | 358 +++++++++++++++ test/test_pandas_ema.py | 81 ++++ test/test_realtime_bbrs.py | 396 +++++++++++++++++ 10 files changed, 2239 insertions(+), 62 deletions(-) create mode 100644 cycles/IncStrategies/README_BBRS.md create mode 100644 cycles/IncStrategies/bbrs_incremental.py create mode 100644 test/debug_rsi_differences.py create mode 100644 test/test_bbrs_incremental.py create mode 100644 test/test_incremental_indicators.py create mode 100644 test/test_pandas_ema.py create mode 100644 test/test_realtime_bbrs.py diff --git a/cycles/Analysis/bb_rsi.py b/cycles/Analysis/bb_rsi.py index cd86488..b166480 100644 --- a/cycles/Analysis/bb_rsi.py +++ b/cycles/Analysis/bb_rsi.py @@ -175,8 +175,9 @@ class BollingerBandsStrategy: DataFrame: A unified DataFrame containing original data, BB, RSI, and signals.
