Order book data in OKX spot trading reflects current market orders, with red indicating sell orders and green representing buy orders. The "best bid" and "best ask" prices show optimal execution points, while bid-ask depth illustrates order concentration and market support—key for assessing trend strength and trade strategy.
Deciphering Order Book Components
What Is Order Book Data?
The dynamic red-green numerical display in OKX's trading interface represents live market orders:
- Sell side (red): Open sell orders at specified prices
- Buy side (green): Open buy orders at specified prices
Three Key Columns Explained (BTC/USDT Example):
| Column | Description | Significance |
|---|---|---|
| Price | Bid/ask price levels | Red = sell intention, Green = buy intention |
| Amount | Order quantity in base currency | Indicates market liquidity at each level |
| Cumulative Value | Total volume from best price outward | Measures depth strength |
👉 Master spot trading strategies
Critical Concepts: Best Bid/Ask & Market Price
- Best Ask (Sell 1): Lowest-priced sell order (immediate buy execution)
- Best Bid (Buy 1): Highest-priced buy order (immediate sell execution)
Market orders execute against these priority levels first.
Understanding Market Depth
Depth = Order volume distribution across price levels
- Strong buy depth = Large buy orders below current price → Price support
- Heavy sell depth = Large sell orders above current price → Resistance
Example: Significant BTC buy orders between $29,900-$30,000 indicate strong demand, while concentrated sell orders above $30,100 suggest upward pressure.
Depth Chart Analysis
Visualize liquidity through the platform's depth chart tool:
- Steep green curve → Concentrated buy orders
- Steep red curve → Concentrated sell orders
- Gentle slopes indicate easier price breakthroughs
Practical Applications
- Order placement strategy: Prioritize best bid/ask levels
- Sentiment analysis: Compare buy/sell volume dominance
- Slippage prevention: Check depth before large market orders
- Bot activity detection: Uniform tiny-spaced orders often indicate algorithms
Common Pitfalls to Avoid
- Mistaking open orders for executed trades
- Assuming visible buy orders guarantee price reversal
- Placing unrealistic limit orders
- Overrelying on depth charts without volume confirmation
