5. Order Types Explained

dob_limit_order_definition

limit_order

maker

Placed at a specific price. Only fills when the market reaches your price. Visible in the order book.

Market Order

taker

Fills immediately at the best available price. Removes liquidity from the book. Subject to slippage.

Stop-Limit Order

conditional

Combines a trigger price (stop) with a limit order. Becomes a limit order once the stop price is hit.

Iceberg Order

hidden

Only shows a small portion of the total order. Used by large traders to avoid revealing their full size.

8. Practical Trading Tips

Combine Book Data with Open Interest

Rising OI with a growing bid wall confirms genuine buying interest. Falling OI with a sell wall suggests position unwinding.

Watch Funding Rates for Context

High positive funding + thin asks = potential short squeeze setup. Negative funding + thin bids = possible long squeeze.

Check Funding Rates →

Use Limit Orders to Reduce Costs

Placing limit orders makes you a market maker — you earn the spread instead of paying it. Most exchanges offer lower fees for makers.

Check Derivatives Volume for Liquidity

Before trading a derivatives contract, check exchange volume. Higher volume = tighter spreads and better fills.

Frequently Asked Questions

What is a derivatives order book?+

A derivatives order book is a real-time list of all open buy (bid) and sell (ask) orders for a futures or options contract. It shows the price, quantity, and depth of liquidity available at each price level.

What is the difference between bids and asks?+

Bids are buy orders — prices traders are willing to pay. Asks (or offers) are sell orders — prices at which traders are willing to sell. The gap between the best bid and best ask is called the spread.

What does order book depth mean?+

Depth refers to the total volume of orders at each price level. A deep order book (lots of orders near the current price) indicates high liquidity and lower slippage. A thin book means large orders can move the price significantly.

What is a spoofing wall?+

Spoofing is when a trader places large orders they intend to cancel before execution, creating the illusion of support or resistance. These 'walls' can mislead other traders into buying or selling. Spoofing is illegal on regulated exchanges.

How do I use the order book to find support and resistance?+

Large clusters of bid orders suggest support (buyers defending a price level). Large clusters of ask orders suggest resistance (sellers capping the price). However, these can be pulled at any time, so combine with other analysis.

What is the bid-ask spread?+

The bid-ask spread is the difference between the highest bid and lowest ask. Tight spreads (e.g., $0.10 on BTC) indicate a liquid, competitive market. Wide spreads suggest low liquidity or high volatility.

Should I rely only on the order book for trading decisions?+

No. The order book is one tool among many. Combine it with open interest, funding rates, volume analysis, and technical indicators for a more complete picture. Order book data can change in milliseconds.
