The Quick Trade Bar is a dynamic tool that allows you to buy and sell market and limit orders for a specific asset class by using a one-click method. This method rapidly places your orders without using the Trade Bar. For Equities and Futures, there are two layout types for the Quick Trade Bar; Standard Buy/Sell and Alternate Sell/Buy view. For Forex, the layout types are Standard FX and Simple FX.
