What Is Dual‑Currency Win?
Dual‑Currency Win is a customized trading tool launched by OKX (Click here to register) that aims to help investors achieve more efficient returns between digital‑asset pairs. After you place a subscription, the system settles according to the agreed‑upon yield, and the currency you receive at maturity depends on whether the actual price of the underlying asset at expiry meets the preset target range.
- If you choose “high‑sell” and the underlying price at expiry reaches or exceeds the target price, the system will sell at the target price, delivering the corresponding stablecoin (denominated in USD) plus the agreed yield.
- If you choose “low‑buy” and the underlying price falls below the target price at expiry, the system will buy at the target price, delivering the target cryptocurrency and the same additional yield.

Dual‑Currency Win Beginner’s Guide
Using BTC as an Example
High‑Sell BTC
First, set a sell price you would like to achieve.
- If, at expiry, BTC’s price does not reach that target, you still receive the agreed‑upon BTC yield.
- If the price reaches or exceeds the target, the system will execute the sale at the target price and additionally credit you with USDT (a USD‑pegged stablecoin).

Scenario 1
Average price on the expiry day below the target price → you obtain extra BTC profit.
Settlement formula:
`Total payout = Subscription quantity × (1 + Yield)`
Scenario 2
Average price on the expiry day not below the target price → BTC is sold at the target price.
Settlement formula:
`Total payout = Subscription quantity × Target price × (1 + Yield)`
*(Denominated in USDT)*
The “expiry‑day price” refers to the weighted‑average index price of BTC during the 15:00‑16:00 (UTC+8) window on the expiry date.
Low‑Buy BTC
Similarly, set a purchase price you would like to achieve.
- If, at expiry, BTC’s price fails to fall to that level, you receive the agreed‑upon USDT yield directly.
- If the price hits or falls below the target, the system will purchase BTC at the target price and also grant you additional BTC.

Scenario 1
Average price on the expiry day not above the target price → successful low‑price purchase of BTC.
Settlement formula:
`Total payout = Subscription amount ÷ Target price × (1 + Yield)`
Scenario 2
Average price on the expiry day above the target price → you obtain extra USDT profit.
Settlement formula:
`Total payout = Subscription amount × (1 + Yield)`
*(Denominated in USDT)*
“Expiry‑day price” again refers to BTC’s average index price during the 15:00‑16:00 (UTC+8) window on the expiry date.
