There are 5 order types you can make:

Limit - is one of the most basic order types. It allows the trader to specify a price and amount they would like to buy or sell.

Market - is an order type that executes immediately against the best price available. As long as there are willing sellers and buyers, market orders are filled. A market sell will match the best available bids on the order book, and a market buy will match against the best available asks on the order book

Stop-limit - is often used as a stop loss order if the market is moving against an open margin position. A trader would place a stop buy below the current price. This would mean that if the market goes against their short (down) they can cut their losses by buying to close or reduce their short position.

Stop-market - if the market price reaches that order price, the order will become "live" and execute as a market order. Market orders are always filled if the price reaches the price specified. This means that with a market order a trader will always get out of the losing trade.

Trailing-stop - provides flexibility over a stop order by executing once the market goes against you by a defined price, called the price distance. When margin trading, a trailing stop sell order can be used to protect profit. The stop price trails behind the market price by the amount specified as price distance and allows for a stop to adjust to the market if the market moves in a profitable direction. If the stop is triggered, a market order is placed.
