- config.json: test_mode=false, ready for sim/testnet trading
- trader.go: auto-stop after 5 real trades, exchange response logging,
Stop()/Start() API, shuttingDown flag for graceful stop
- dashboard.go: POST /api/stop + POST /api/start endpoints,
trading status in SSE stats
- exchange/hyperliquid.go: switch HL WS to testnet endpoint
- exchange/hyperliquid_trade.go: switch REST to testnet endpoint,
support base64 + 32-byte EVM private keys
- main.go: listen on trader.StopCh (graceful, no process exit)
- scanner.go: trim TrackedCoins to only 6 core coins (DOGE/LINK/ONDO/OP/WIF/ARB)
- .gitignore: ignore main binary
Bitget v2 WS requires a text message "ping" every 30s, not a WebSocket
PingMessage control frame (opcode 0x9). Using the wrong ping type caused
a silent failure: connection stays up and subscription succeeds, but NO
ticker data is pushed — zero errors, zero reconnection logs.
Changes:
- connector.go: Add TextPing bool flag, send text 'ping' when set
- bitget.go: Set TextPing=true, handle text 'pong', add debug logging
- scanner.go: Expand to 179 overlapping Bitget+HL coins
1. GetHLSize: add minimum size checks (prevent size=0 when price > amount)
2. executeEntry: orphan position warning when leg1 close also fails after leg2
3. checkExit: keep position as close_failed on failure, retryClose on each Tick
4. persistTrade: sync instead of goroutine (prevent data loss on exit)
During async executeEntry goroutine, the 300ms sleep between legs
left the position vulnerable to checkExit() from the main loop.
Added intermediate Status='entering' that checkExit/checkScaleIn
skip ('entering' != 'open'), switched to 'open' only after both
legs are placed.
- TryEntry now spawns a goroutine for order placement
- Main loop continues at 50-250ms even during entry
- 'entering' map prevents duplicate entries on same coin
- Async cleanup of entering state on completion
- Remove DetailedStats struct and GetDetailedStats() method from trader.go
- Add calcDetailedStats() standalone pure function in dashboard.go
- Dashboard calls d.trader.GetClosedTrades() + calcDetailedStats()
- Trading logic now has zero display-oriented calculations
- Add start.sh to Quick Start section and project file tree
- Remove broken cp .env.example reference (no such file)
- Annotate .env with config categories
- Replace manual spread-fee calc with netProfit() call — matches
scanner's exact fee model (round-trip 0.07%)
- Each direction gets correct buy/sell fee pairing
- Add PeakNet field to record true max during window, not close-time value
- Log peak net with +/- sign instead of approx symbol
- New SpreadWindowTracker in types.go watches BG↔HL spread for all
tracked coins, both directions
- Logs duration when spread stays above trade threshold then converges
- Wired into main loop after each scan tick
- Filters sub-100ms windows as noise
- Remove goroutine in TryEntry (executeEntry now synchronous)
- Use opp.BuyPrice/SellPrice directly instead of re-reading from store
- Keep lightweight direction sanity check (0.1% tolerance)
- executeEntry returns bool for call chain consistency
