Passivbot v7.5.0 (TWEL Enforcer)

Passivbot v7.5.0 (TWEL Enforcer)

Highlights

• Risk controls & TWEL enforcer

  • Added risk_we_excess_allowance_pct, risk_wel_enforcer_threshold, and companion Rust helpers that auto-reduce positions when wallet exposure drifts beyond the buffer.
  • Implemented TWEL (Total Wallet Exposure Limit) gating in Rust with Python wiring, per-position prioritisation, and optimizer bounds/CLI flags.
  • Refined unstuck logic so both live bot and backtester use the same Rust helpers; unstuck can now be disabled by setting a negative threshold.

• Optimizer overhaul

  • Shared-memory HLCV bundles and per-scenario slicing remove per-worker copies, cutting RAM growth as CPU count increases.
  • Streaming evaluator outputs: each candidate logs Pareto updates immediately, duplicate detection got stricter, and starting-config logging/immediate termination handling improved.
  • Suite support landed: optimisations can now evaluate multiple scenarios per candidate (with config cleaners, override helpers, and scenario metrics aggregation).
  • Added Pareto dashboard (WIP) and metrics-only mode; template configs updated with new suites and defaults.

• Logging & monitoring

  • Order-plan logging is now quiet when unchanged, but includes delta/context details when cancels/creates actually happen; tolerance gating prevents churn.
  • Candlestick manager detects sparse exchange feeds once per (exchange,symbol,tf) and still standardises gaps with synthetic zero-candles.
  • Balance snapshot/logging knobs moved to config.logging; log-once helper ensures repeated warnings appear only once per symbol.

• Config & CLI improvements

  • Template config refreshed with new risk knobs, trailing weights, and optimizer bounds; config_utils tracks transforms and exposes _raw data.
  • CLI overrides for optimise bounds now only freeze the key you actually pass (e.g. -lnp 4 pins long positions to 4, leaving other bounds untouched).
  • Added knobs such as recv_window_ms, balance_sample_divider, logging.volume_refresh_info_threshold_seconds, and updated docs.

• Backtest & analysis

  • Introduced HlcvsBundle and payload subset helpers; backtest payloads now carry coin metadata in Rust and Python tests cover slicing/validation.
  • New scoring metrics (entry_initial_balance_pct_long, drawdown limits, volatility-weighted trailing entries) and renamed config fields to match.
  • Added scripts/tools (shared_arrays.py, JSON streamliner, new Pareto utilities) plus doc updates (passivbot_agent_principles.yaml, CONTRIBUTING).

• Fill events manager (WIP)

  • New src/fill_events_manager.py adds modular fetchers (Bitget, Bybit, Binance) with caching and enrichment plus a CLI runner and tests. Live bot still uses legacy fetch_pnls; the manager will coexist while it matures.

Thanks to everyone who tested TWEL enforcer, optimiser RAM fixes, and the expanding docs/tooling ecosystem.
