Bybit Trading Bot Developer for Unified v5 API
We integrate Bybit unified trading accounts with correct category params, position idx, and demo-main parity—so your bot works on testnet before capital hits unified margin.
Bybit v5 migration broke many bots
Category (spot, linear, inverse), positionIdx, and unified account changes cause subtle order rejections. Docs lag real edge cases on partial TP/SL linkage.
- ×Legacy v3 endpoints deprecated while production still calls them.
- ×Hedge vs one-way positionIdx errors open unintended side exposure.
- ×Unified account transfers blur spot and perp balance accounting.
- ×Demo trading keys behave differently without explicit demo flag handling.
Bybit-native connectors and state sync
v5-only gateways with category-aware routers, wallet balance reconciliation, and websocket private channel recovery.
- Clean migration path from legacy Bybit integrations.
- Correct TP/SL placement on linear and inverse contracts.
- Spot-perp arbitrage within unified account constraints.
- Demo-to-main config switch with identical code paths.
