- ArbTable: removed slice(0,10) cap, shows all 42 opps (21x2)
- PriceTable: added net_bg_to_hl and net_hl_to_bg columns
- Backend SSE: sends net profit for both directions per coin
HL testnet USDC lives in the spot account, not the perp clearinghouse.
GetBalance() was calling UserState() (perp clearinghouseState), which
returned /usr/bin/bash. Switched to SpotUserState() and parse USDC.total - USDC.hold.
Also cleaned up .gitignore to exclude .env, binary, logs, data/.
B#1 — sigCh shared across goroutines, SIGINT unreliable
→ context.WithCancel: main loop cancels ctx on SIGINT,
4 WS goroutines select on ctx.Done() instead of shared sigCh
B#3 — restoreOpenPositions missing LastScaleAt
→ Set LastScaleAt = tr.OpenedAt on restore so scale-in cooldown works
B#4 — dYdX heartbeat goroutine leaks on reconnect
→ Added stopHeartbeat chan + heartbeatMu mutex; close old channel
before spawning new heartbeat goroutine
B#5 — GetBitgetSize fmt.Sprintf rounds up, may exceed amountUSD
→ Added math.Floor(sz*multiplier)/multiplier before format to round
DOWN to nearest valid step size for every coin
B#6 — netProfit and CalcNetProfit duplicate formula
→ scanner.go netProfit now delegates to exchange.CalcNetProfit
B#7 — Aevo Run callback only 2 params, incompatible with startExchange
→ Changed to 4-arg callback func(coin, price, bid, ask) with bid=ask=0
B#8 — parseFloat uses fmt.Sscanf (slow, locale-sensitive)
→ Replaced with strconv.ParseFloat
B#9 — dYdX receives hlSymbols instead of its own symbol list
→ Added dydxSymbols var, built from c.HL like other exchanges
