Understanding Spot Trading
Spot trading refers to the direct exchange of one cryptocurrency for another at current market prices. For example, in the ETH/BTC trading pair, ETH acts as the base currency while BTC serves as the quote currency - essentially meaning you're using Bitcoin to purchase Ethereum.

Cost Price Calculation in Spot Trading
OKX introduced spot cost price calculation on August 29, 2024, featuring two distinct methods:
Cost Price Overview
| Metric | Average Cost Price | Cumulative Cost Price |
|---|---|---|
| Definition | Average purchase price | Net cost considering all trades |
| Calculation | (Prior avg × Qty + New price × Qty) / Net quantity | (Total buy value - Total sell value) / Net quantity |
| Profit Formula | (Current price - Cost) × Net qty | Current price × Net qty - Total buy + Total sell |
| ROI Calculation | (Current - Cost)/Cost | Profit/(Total buy - Total sell) |
| Best Use Case | Buy/sell timing decisions | Optimal selling point analysis |
Practical Calculation Examples
Scenario 1: Initial Purchase
- Buy 2 ETH @ 3,000 with current price @ 3,500
Average Cost: 3,000
- Profit: (3,500-3,000)×2 = 1,000
- ROI: 16.67%
Cumulative Cost: 3,000
- Same results initially
Scenario 2: Partial Sale
- Sell 1 ETH @ 3,500 (current @ 4,000)
Average Cost: Maintains 3,000
- Profit: 1,000 (33.3% ROI)
Cumulative Cost: 2,500
- Profit: 1,500 (60% ROI)
Scenario 3: Additional Purchase
- Buy 1 ETH @ 4,000 (current @ 4,500)
Average Cost: 3,500
- Profit: 2,000 (28.6% ROI)
Cumulative Cost: 3,250
- Profit: 2,500 (38.5% ROI)
Key Considerations
- Cost calculations only apply to trades occurring after implementation date
- Future updates will allow manual cost price adjustments
- Only spot trades and strategy transfers included
- Stablecoins and fiat excluded from cost calculations
