From a924328c9094d21db3be8c91a5be2beb01eebd7c Mon Sep 17 00:00:00 2001 From: Ajasra Date: Thu, 22 May 2025 16:44:59 +0800 Subject: [PATCH] Implement Market Regime Strategy and refactor Bollinger Bands and RSI classes - Introduced a new Strategy class to encapsulate trading strategies, including the Market Regime Strategy that adapts to different market conditions. - Refactored BollingerBands and RSI classes to accept configuration parameters for improved flexibility and maintainability. - Updated test_bbrsi.py to utilize the new strategy implementation and adjusted date ranges for testing. - Enhanced documentation to include details about the new Strategy class and its components. --- cycles/Analysis/boillinger_band.py | 51 ++++++++--- cycles/Analysis/rsi.py | 6 +- cycles/Analysis/strategies.py | 131 +++++++++++++++++++++++++++++ docs/analysis.md | 63 ++++++++++++++ docs/strategies.md | 43 ++++++++++ test_bbrsi.py | 65 ++++++++------ 6 files changed, 315 insertions(+), 44 deletions(-) create mode 100644 cycles/Analysis/strategies.py create mode 100644 docs/strategies.md diff --git a/cycles/Analysis/boillinger_band.py b/cycles/Analysis/boillinger_band.py index 64d1e36..65801ca 100644 --- a/cycles/Analysis/boillinger_band.py +++ b/cycles/Analysis/boillinger_band.py @@ -4,23 +4,25 @@ class BollingerBands: """ Calculates Bollinger Bands for given financial data.
