v1.21.0 introduces robust per-market weather station routing and expanded coverage for more accurate weather market trades. - Each market now routes to the specific weather station named in its `resolution_criteria`, matching Polymarket's source rather than using a fixed default. If a station is not recognized, the market is skipped with a log message. - Expanded NOAA station support: now covers KLGA, KJFK, KEWR, KNYC, KORD, KMDW, KSEA, KATL, KDAL, KDFW, KMIA, KBOS, KDCA, KIAD, KPHX, KLAS, KSFO, KLAX, KDEN, KMSP, KPHL. - Added international Open-Meteo routing for Madrid, Milan, Amsterdam, Taipei, as well as previously supported cities. - The skill now requires the new `?include=resolution_criteria` flag when calling `/api/sdk/markets` (supported as of 2026-05-03).

v1.20.1 — ASI scanner reframe per engine v2.4.22 calibration. Adds Safety rails (read first) section surfacing the bounding contract (dry-run default, --live opt-in, $SIM paper sandbox, linked-wallet requirement, configurable caps, server-side stop-loss ON, strategy-side safeguards, reversibility). Genericizes risk monitor framing (stop-loss/take-profit thresholds described as configurable user settings — sidesteps a code-vs-DB-default divergence tracked in a separate platform consolidation). Drops named cross-skill link in Setup section. Strategy logic + env var contract unchanged from v1.20.0. Requires simmer-sdk >= 0.13.0.

v1.20.0 — Phase 3 canary of skill catalog reshape. Migrated to simmer-sdk 0.13.0 helpers (SimmerClient.from_env() replaces direct os.environ reads). Removed dead AUTOMATON_* env reads (automaton retired 2026-04-20). Slimmed SKILL.md (303 → 203 lines): dropped duplicated wallet setup content, trimmed example output, reworded cross-skill reference. Strategy logic, env var contract for SIMMER_WEATHER_*, and TRADING_VENUE behavior unchanged. Requires simmer-sdk >= 0.13.0.

V2 migration (2026-04-28): updated troubleshooting copy to point users at the Wrap USDC.e → pUSD flow at simmer.markets/dashboard + docs.simmer.markets/v2-migration. Also refines clawhub.json envVars schema (WALLET_PRIVATE_KEY now correctly optional for managed-wallet users).

Schema fix: primaryEnv + envVars with required:false for optional credentials. Clears OpenClaw 'disproportionate requirements' verdict.

Declare WALLET_PRIVATE_KEY in requires.env for OpenClaw moderation alignment.

SKILL.md content revision: frames paper mode and $SIM venue as test features. No code/config changes from 1.18.0.

v1.18.0: clawhub.json autotune defaults realigned with code defaults (entry 0.15, exit 0.45, max , sizing 0.05); 7 additional tunables exposed for autotune (LOCATIONS, BINARY_ONLY, SLIPPAGE_MAX, MIN_LIQUIDITY, VOL_*); max_position_usd range tightened to [1,50] and sizing_pct to [0.01,0.25]; SKILL.md updated with server-side risk-monitor framing. No code behavior changes — tunable surface only.

**v1.17.0 introduces dynamic position sizing using volatility targeting.** - Adds volatility targeting mode: dynamically adjust trade size based on recent market volatility (enable with `--vol-targeting` or `SIMMER_WEATHER_VOL_TARGETING`). - New configuration parameters: `SIMMER_WEATHER_TARGET_VOL`, `SIMMER_WEATHER_VOL_MAX_LEVERAGE`, `SIMMER_WEATHER_VOL_MIN_ALLOC`, and `SIMMER_WEATHER_VOL_SPAN` for managing volatility targeting behavior. - Position size will decrease in high-volatility markets and increase (capped) in low-volatility markets. - Volatility calculated with EWMA of log returns from price history. - All previous features and safeguards remain available.
