Passivbot v7.5.7

Passivbot v7.5.7 Release Notes

Highlights

• CCXT upgrade to 4.5.22 for better exchange compatibility, along with KuCoin hedge-mode enforcement and order payload fixes.
• Canonical suite metrics & Pareto revamp ensuring optimizer/backtester share identical outputs, with centralized Pareto logic.
• Cleaner balance/position orchestration: bots fetch balance and positions concurrently, logging once both are fresh.

Detailed Changes

Exchange & Bot Behavior

• Upgraded CCXT to v4.5.22 and added regression tests to detect future CCXT-breaking changes.
• KuCoin bot now enforces hedge mode (when supported), handles exchange refusal gracefully, and sends correct marginMode/positionSide order params.
• All exchange wrappers now keep fetch_positions() and fetch_balance() separate; callers can refresh each independently.
• update_positions_and_balance() gathers balance/positions concurrently, logs position deltas after both complete, and emits a single balance-change event so equity logging always uses fresh positions/uPnL.

Optimization & Backtesting

• Added pareto_core.py consolidating Pareto dominance/crowding logic with extreme-preserving pruning.
• Suite runner and optimizer now emit the same canonical suite metrics payload (aggregate stats + per-scenario means).
• ParetoStore delegates to the shared helper so dominance/clustering rules are consistent across CLI tools.

Configuration & Overrides

• Added forward/backward TP grid overrides (PR #532) plus template/normalize fixes when loading live or suite configs.
• Improved parse_overrides behavior and logging for suite enablement.

Documentation

• Expanded docs covering minimum effective cost calculations, trailing grid ratios, and the new changelog policy.
• Documented KuCoin hedge-mode setup so users know what to expect after the CCXT upgrade.

Testing & Tooling

• New KuCoin exchange-config regression tests (hedge/margin/leverage) plus refreshed passivbot balance tests.
• Updated test stubs so passivbot_rust/CCXT mocks reflect the new fetch/log separation.

What's Changed

• Bring back forward/backward TP grid logic by @Couillos in #532
