When it comes to trading, selecting the right order type can make a significant difference in transaction fees.

First, let's talk about what an order is. Simply put, it's the instruction you give to the exchange saying, "I want to buy/sell a certain coin at what price and when to execute."

**Limit orders and market orders are vastly different**

There are two factions in the trading circle:

**Maker** - You place a price and wait; if no one takes it, you just leave it there, adding liquidity to the market. The benefit is lower transaction fees, with mainstream platform contract order fees generally at 0.02%. Patience brings savings.

**Taker** - Impulsive, directly taking the orders placed by others on the order book, resulting in immediate transactions. The cost is a bit high for fees, usually 0.06%. Speed comes at a cost.

**Which orders are supported by mainstream exchanges?**

The common types of contract orders currently include the following:

1. Market Order
2. Limit Order
3. Planned Entrustment
4. Only place Maker orders
5. Tracking Orders
6. Segmented Orders
7. Iceberg Order
8. Time-sharing Order

Each type of order has its own applicable scenario. By understanding their logic and triggering mechanisms, you can flexibly switch strategies according to market rhythms—act quickly when needed and save when possible.

Whether you can play contracts smoothly often depends on whether you know how to use these tools. Next time, let's talk specifically about how to use each type of order most cost-effectively.
