Binance: one-way mode

Futures bots need one-way positions, and Multi-Assets Mode off for isolated margin.

The steps, in words

1. Open Preferences on the futures page
   On the Futures trading page tap ··· in the top right and choose Preferences.
2. Open Position Mode
   Under the Trading Mode tab tap Position Mode. The same list shows Account Mode: on Unified Account spot and futures share one balance; on the classic account they are two wallets and the funding step below applies.
3. Choose One-way Mode
   Pick One-way Mode. Hedge mode needs a position side the engine never sends, so the first short would be refused. Close any open position first — the mode is locked while one is held.
