From cd9f58fe8237f0641a4f971ea9242e4c95ecc678 Mon Sep 17 00:00:00 2001 From: GifariKemal Date: Wed, 11 Feb 2026 20:30:50 +0700 Subject: [PATCH] fix(v0.2.5): monotonic loss ratchet + golden session + never-profitable grace - Fix #3: Grace period capped at 2min for trades that NEVER saw profit - Fix #4: effective_max_loss and max_atr_loss can only tighten (monotonic) - Golden Session: loss_mult*0.70, profit_mult*0.85, grace*0.60 - market_context now includes is_golden, session_name, session_volatility - Enhanced dynamic log with [GOLDEN] tag, ratchet values, ever_profitable Co-Authored-By: Claude Opus 4.6 --- CHANGELOG.md | 38 +++++++++++++++++++++++++++++ VERSION | 2 +- main_live.py | 8 +++++++ src/smart_risk_manager.py | 50 ++++++++++++++++++++++++++++++++++++--- 4 files changed, 94 insertions(+), 4 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index 1e6160a..f7d8288 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -9,6 +9,44 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0 --- +## [0.2.5] -
