- marginOverheadFactor/takerFeeRate/positionSizeSafetyFactor in sizing math
- aggressiveBuyPriceFactor/aggressiveSellPriceFactor in hyperliquid and aster
simulated market orders
- dustQuantityEpsilon in FIFO position rebuild
- binance/bybit/gate: SDK default http.DefaultClient has no timeout; use a
dedicated 30s-timeout client so a hung connection cannot stall the loop
- bybit: stop mutating http.DefaultClient.Transport, which leaked the
referer header into every other HTTP request in the process
- add types.ParseFloatField: empty exchange fields stay zero, but malformed
numeric values now surface as errors instead of silently becoming zero
balances (applied to GetBalance across 8 exchanges)
- wrap order/market-data errors in auto_trader_orders and okx cancel paths
with symbol context; log per-order cancel failures in okx CancelAllOrders
