Order type	Meaning
Market Orders (MKT) 市价	buy or sell at the current price
Limit Orders (LMT) 限价	buy or sell an asset at a specific price or better
Stop Orders (STP) 止损市价, or stop-loss	buy or sell an asset at the best available price but only if the market reaches a specific price
Stop-Limit Orders (STPLMT) 止损限价	combine a stop order (trigger price) and a limit order to fine-tune what price
Trailing Stop Orders
Market-If-Touched (MIT) Orders 触及限价	Market-if-touched orders are similar to limit orders, except they don't guarantee a price
Limit-If-Touched (LIT) Orders 触及市价	like an MIT order, but it sends out a limit order instead of a market order

Basic:

A market order is used to enter or exit a position quickly. This is the quickest way to fill an order, but it gives you the least control over the price.
A limit order, on the other hand, ensures minimum selling prices and maximum buying prices, but they won't execute as quickly.

A Stop orders are used to limit your losses with a market order when a trade turns against you.
A Stop-limit orders employ the same tactics, but they use limit orders instead of market orders.
A Trailing stop orders and trailing stop-limit orders use the same strategy to protect profits.

A Market-if-touched orders trigger a market order if a certain price is touched.
A limit-if-touched order sends out a limit order if a specific trigger price is reached.

Basic Rule

If you are looking to buy

If trigger price > current price, use a stop/Stop-Limit order 止损市价/限价 –涨至xxx（如带柄匙状成型）买入-右侧交易
If trigger price < current price, use a market-if-touched order 触及市价/限价 –跌至xxx买入（价格足够低而买进）-左侧交易

If you are looking to sell

If trigger price > current price, use a market-if-touched order 触及市价/限价 –涨至xxx卖出（获利离场）
If trigger price < current price, use a stop/Stop-Limit order 止损市价/限价 –跌至xxx卖出（止损离场）
