There are 2 types of orders: Long (buy) and Short (sell) positions. They characterize the trade order entries based on possible cryptocurrency price movements.
Using a buy limit order allows you to specify the exact price you want buy CFDs. This price is typically a calculated entry point.
A stop order includes a stop price that then triggers the allowance of a market order. If the market price moves to the stop price, then a market order to sell is triggered. Until these conditions are met, it is a pending order and does not affect your account totals or margin calculation.
Market orders (buy or sell) are transactions meant to execute as quickly as possible at the current market price.
