How to set up Alerts on price?

In order to enable an alert that will be triggered when the price approaches the line, you need to set a horizontal line on the chart and enable the Approximation Alert option in the line settings.

The Approximation Filter parameter is responsible for the distance at which the alert will sound. The distance is measured in ticks from the line to the price.

Similar sound alerts are available in the Smart Tape and in the Order Flow Indicator.
