Error message

market must be one of cn, hk, us, jp, kr, tw

What it means

ValueError from DecisionSignalService._normalize_market (src/services/decision_signal_service.py:1137): the market field is lowercased/stripped and must be one of VALID_MARKETS = {cn, hk, us, jp, kr, tw}. Anything else — including localized names like 'A股', 'china', exchange names, or case/typo variants not fixed by lowercasing — is rejected.

Solutions

1. Map provider values to the six supported tokens before the call (CHN→cn, HKG/hkex→hk, USA/NASDAQ→us, JPY/japan→jp, KRW/korea→kr, TAIEX→tw).
2. Use _normalize_optional_market / the API's optional field when market may be absent instead of sending placeholder strings.
3. If you genuinely need an unsupported market, extend VALID_MARKETS and update docs/tests — do not bypass the check.
4. Add a client-side enum guard (see validationCode).

Example fix

# before
service.create_signal({"stock_code": "00700", "market": "HKG", "action": "buy"})  # ValueError

# after
MARKET_MAP = {"CHN": "cn", "HKG": "hk", "USA": "us"}
market = MARKET_MAP.get(provider_market, provider_market.strip().lower())
service.create_signal({"stock_code": "00700", "market": "hk", "action": "buy"})

VALID_MARKETS = {'cn', 'hk', 'us', 'jp', 'kr', 'tw'}
market = str(payload.get('market') or '').strip().lower()
if market not in VALID_MARKETS:
    raise ValueError(f'market must be one of {sorted(VALID_MARKETS)}')

def is_valid_market(v) -> bool:
    return str(v or '').strip().lower() in {'cn', 'hk', 'us', 'jp', 'kr', 'tw'}

When it happens

Trigger: create/update signal payloads with market: 'zh', 'CN ' (ok after trim/lower → 'cn'), 'a_share', 'sh', 'hongkong', 'USA', 'japan', 'TSE', or None/'' when market is required. _normalize_optional_market tolerates None but any non-empty wrong value hits this error.

Common situations: Mapping from a provider that uses ISO country codes (CHN/HKG/USA) or exchange codes (SH/SZ/HKEX/NASDAQ) directly to market; locale-dependent labels; adding a new market to the enum without updating callers; data pipelines forwarding the stock's currency ('CNY'/'HKD') as market.
