Dynamic Profiles allow the price action of the market to dictate the duration of a profile. As price continues to trade within a given range, a profile will continue to build. New profiles are only formed once price moves to new levels relative to recent bars.
Setup the Profile Indicator with "Time Per Profile" preferences seen below. Notice that "Custom" is checked, with "3 Sessions" selected from the list box to the right. In this example, we will only be using 2 sessions but 3 sessions is possible. Just under "Per 1" is where we specify the 1st period (or first session) in minutes.
These labels can be turned off by unchecking the "Labels" checkbox in the Profile Indicator Preferences.
