The index automatically assembles significant trend lines and shows purchase and sell signals. Signals are formed for reflection and for a breakdown out of the resistance and support lines. When a sign arises, the index displays it as an arrow of the specified colour and also sends the type of messages specified in the input . In the index settings, you can set the signal type, the maximum distance to the trend line, the type of alarms, as well as the settings of the lines and arrows.
