Foreign exchange (Forex) trading involves two key pricing terms: bid price and ask price (denoted as BID/ASK). These terms represent the perspective of the trading bank and refer to the base currency in a quoted pair.
What Are Bid and Ask Prices?
- Bid Price: The price at which a bank buys one unit of the base currency from you.
- Ask Price: The price at which a bank sells one unit of the base currency to you.
The difference between these prices—known as the spread—directly impacts trading costs. A narrower spread means lower expenses for investors.
How Spreads Work in Forex Trading
- Interbank Trading: Typically has a tight spread of 2–3 pips.
Retail Trading: Spreads vary significantly among brokers or banks. For example:
- International margin trading: 3–5 pips
- Hong Kong markets: 6–8 pips
- Mainland China banks: 10–40 pips (for spot transactions)
Example: EUR/USD Exchange Rate
| Currency Pair | Bid Price (Buy) | Ask Price (Sell) |
|---------------|-----------------|------------------|
| EUR/USD | 1.2807 | 1.2810 |
- Scenario 1 (Buying EUR): You pay the bank’s ask price of 1.2810 USD per euro.
- Scenario 2 (Selling EUR): You receive the bank’s bid price of 1.2807 USD per euro.
💡 Note: Bid/ask prices fluctuate in real-time. Actual rates depend on your bank’s柜台交易 rates.

- Cost Efficiency: Smaller spreads reduce transactional costs.
