# 【Trader】Scenarios Where Copy Trading Fails

The trader and the copier must both use the **Hedging Mode** (two-way position mode). If the trader uses **One-Way Mode** while the copier uses Hedging Mode, the copy trade will fail – and vice versa.

On the OKX exchange, go to **"Trade Settings"** to adjust your position mode.

Tap "Position Mode"

Select "Hedging Mode" (two‑way position mode).

**Note:** Failing to switch to Hedging Mode (two‑way position mode) will prevent you from placing or copying trades.
