A Binance Futures bot doesn’t fail only because the signal is bad.
Sometimes it fails because the account state is stale.
I ran into this last week: one order partially filled, the websocket reconnected 1.8 seconds later, and the bot briefly treated the account like it was flat.
That is where duplicate orders start.
My basic Binance Futures rule now:
1. Sync account state after every reconnect
2. Track pending orders separately from open positions
3. Add a cooldown after every fill
4. Cancel stale orders before new entries
5. Log rejected signals, not only filled trades
6. Stop trading after 3 failed order attempts
Boring fix, real edge.
Most bot builders optimize entries first. I’d rather fix state recovery before adding another indicator.
A bot without clean state handling is just revenge trading with Python.
For Binance Futures bots, I care about:
- last fill time
- position size
- margin mode
- open orders
- rejected signals
- reconnect count
- cooldown status
If your bot can’t answer those before placing the next order, it shouldn’t place the order.
Would you rather reduce trade count by 20%, or keep one hidden duplicate-order bug alive?
