Markets really love round numbers and they often act as support in a falling market, or resistance as price rises.

This indicator is designed to draw price levels at Round values. It does this automatically, but you also have the option to override that and determine the levels you wish to see.

A round level can be as simple as steps of 10, so 10, 20, 30 etc or if you are working with Forex, maybe you want to see changes at 0.1 or 0.01.

The indicator draws two classes of line, Major and Minor, each with a different format. This allows you to see changes between two different changes in level at the same time.

The indicator includes the ability to sound alerts at either Major, Minor or both price levels when price comes within a configurable distance.

Automatic Setup

By default, the indicator will determine an appropriate level for both Major and Minor prices. It does that using a configurable DensityIndex setting which controls how many lines you want to see on screen at any time.

If you set your own scaling, using the MajorGap and MinorGap settings, you can still get the indicator to limit the number of lines drawn on screen by using the ReduceAtScale setting.

Please see the screenshots for a clearer idea of this feature.

UseNotificationAlerts

Send a notification using the MT4 notifications system when an alert is triggered. See the main menu Tools > Options then select the Notifications tab and setup in there. You will also need the Apple or Android app.
