The ORB with Price Targets Script will display the Opening Range (15 minutes of the open session by default) High and Low. It will then render upper and 2 lower Price Target Levels based on 50% and 100% profit targets of the Opening Range.
The opening range is customizable in the settings, where you can choose from 5 minute, 15 minute, or 30 minute Opening Ranges.

Price action also tends to find support and resistance at the 50% and 100% retracement levels, thus providing you Price Targets to start trimming your position, or finding new entries.
