A single-symbol QNT-USDC trader produced 0 candidate coins, 500 errors
from Hyperliquid, and "🚫 Dropped AI decision" warnings — the agent had
no market data to reason about, so it sat in `wait` forever. Three
chained bugs:
1. provider/hyperliquid/kline.go (IsXYZAsset / FormatCoinForAPI):
asset detection required the base symbol to appear in the hardcoded
StockPerpsSymbols / XYZOtherSymbols / display-alias lists. QNT, ARM,
and every other newly-listed Hyperliquid USDC perp wasn't in the
list, so the code routed them to the crypto path (CoinAnk) which
doesn't have them. Now the `-USDC` suffix and `xyz:` prefix are
trusted as definitive Hyperliquid signals — these tokens are
Hyperliquid-specific and new listings don't require a code change.
The hardcoded lists are kept as fallbacks for bare base symbols.
2. market/data_klines.go (getKlinesFromHyperliquid): the function
stripped the `xyz:` prefix before calling GetCandles, defeating
GetCandles's own FormatCoinForAPI logic. With the hardcoded list
missing the new ticker, FormatCoinForAPI couldn't re-add the prefix
and the request hit Hyperliquid's crypto perp endpoint — which
returns 500 for stock-only tickers. Pass the symbol through as-is.
3. trader/auto_trader_loop.go (filterDecisionsToStrategyUniverse): the
AI sometimes echoes a candidate as "QNTUSDC" / "QNT-USDC" / "QNTUSDT"
/ bare "QNT" instead of the canonical "xyz:QNT" we supplied. Strict
exact-match was dropping all of them. Added a base-level key
(strips xyz:, -USDC, -USDT, USDC, USDT, USD; normalizes display
aliases like ROBINHOOD → HOOD) and rewrites the matched decision's
symbol to the canonical form so the order pipeline downstream sees
the format it expects.
After this, a single-symbol stock trader fetches real K-line data from
Hyperliquid, the AI sees real candidates, and decisions get executed
on-chain instead of silently filtered.
