Entering a Limit Order

The presenter talks about entering a limit buy order in the forex market.  He illustrates how to do this using the Metatrader platform.  Limit orders allow you to enter a standing order to buy at a price which is below the market.  This price is basically your limit to how much you are willing to pay for a security.  If a limit order does not get filled, it will be out there indefinitely, or until cancelled, if it is a good to canceled order.
