The ability to individually adjust the Gann Fan levels to a specific point is not available in Optuma currently (you can extend / retract all levels as one).
require the feature to Avoid messing up the chart. there is the same feature in other software.
Unfortunately, this is something I will not do. Like traditional support and resistance, Gann Fan Lines get tested over and over again in the future. To cut them short on the first crossing is to miss vital information.
