It’s human nature to prefer round numbers. Because of this, amateur traders will often place profit targets and stop losses at round numbers. Professional traders know this, and are able to take advantage of it. Round numbers will often act as levels of support and resistance.
This TradeStation indicator tells you where the round numbers are, so you can keep them in mind while placing targets and stops. It works with any type of symbol, no matter how large or small, including forex, on any time frame. You can choose the amount by which numbers are rounded, and you can choose to display as many or as few lines as you want. The appearance and style of the lines are customizable.
