What is a Limit Order? How do I enter a limit order?

A Limit Order is a type of order where you can place a buy/sell order at any price.
According to the dynamics, your buy/sell order is executed if there is a buyer/seller in return for your trade. There is no guarantee that your limit orders will be executed.
If there is an open order in your account, it will be deducted from your available balance because your balance is blocked as much as your relevant order . If you want to use your balance in a different transaction, you must first cancel your open order. You can view your open orders from the My Open Buy Orders and Open Sell Orders headings in the section at the bottom of the stock exchange page and delete your open order with the CANCEL option on the right side.
