Be cautious with referral codes or links that make vague promises without identifying who provides them or what you receive. SmallDrift’s official link carries RATE20 to Binance and provides a 20% trading-fee discount. For transparency, Binance’s signup screen displays SmallDrift, RATE20, the fee discount, and the referral benefit before you create the account.

What Is an Order Book?

The order book shows all pending buy and sell orders for a trading pair at different price levels. It’s the heart of how exchange trading works.

Order Book Structure

Left Side: Bids (Buy Orders)

Green colored
Shows prices people are willing to buy at
Sorted highest to lowest (best bid on top)

Right Side: Asks (Sell Orders)

Red colored
Shows prices people are willing to sell at
Sorted lowest to highest (best ask on top)

The Spread

The gap between the best bid and best ask is the spread. Tighter spread = more liquid market.

Example:

Best bid: $99,990
Best ask: $100,010
Spread: $20 (0.02%)

How to Read Depth

Each price level shows:

Price: The order price
Amount: How much crypto is available at that price
Total: Cumulative amount from the best price

What the Order Book Tells You

Large Buy Wall

A very large bid at a specific price suggests strong support. Buyers are willing to absorb selling pressure at that level.

Large Sell Wall

A very large ask at a specific price suggests resistance. Sellers are waiting to dump at that level.

Thin Order Book

Few orders at each level means:

Higher slippage for large orders
More volatile price movements
Be careful with market orders

Using the Order Book for Trading

1. Check Liquidity Before Trading

If you’re placing a large order, check the depth to estimate slippage.

2. Identify Support/Resistance

Large order clusters can act as temporary support or resistance.

3. Set Limit Orders Strategically

Place your limit orders at or near large bid/ask clusters for higher fill probability.

Limitations

Spoofing: Large orders can be placed and cancelled to manipulate perception
Hidden orders: Some orders are iceberg orders (only partially visible)
Dynamic: The order book changes every millisecond

Pro Tip

On Binance, switch between the order book view and depth chart. The depth chart visualizes the order book as a graph, making it easier to spot support/resistance walls.

Referral safety check

Be cautious with referral codes or links that do not clearly identify their provider and benefit. SmallDrift’s official RATE20 link provides a 20% trading-fee discount, and Binance’s signup page transparently displays SmallDrift, RATE20, the discount, and the referral benefit before account creation.
