What are simple alert conditions?
Get a handle on this and you can create your own indicators
When you need some kind of alerting on a typical condition, the first step is to look into simple alert conditions. Most cases you can get a long way applying them to your use case.
Simple alert conditions can serve you to define trading signals or used to get alerted by email or SMS when you the alert condition is fulfilled.
Alert conditions can be placed in separate locations:

Chart Level Alert conditions

Chart Settings Alert Tab. Alert conditions placed in this area will be in effect and evaluated for the particular chart it is used on.

Study Level Alert conditions

It is also possible to place an alert condition inside the study settings of a particular study. This gives you more flexibility monitoring for certain conditions.
The Study Settings Alert Tab is a place holder for alerts that will be in effect and evaluated on the chart the study is loaded on.

Alert Settings

Remember to assign Alert Number actions in the Global Setting >> General Settings >> Alerts/General 3 section.
General Alert Settings - configure each alert reaction
When alerts fire you can also see them in the Alert Manager.

CBBOAC

The most powerful study to use with simple alert conditions is the "Color Bar based on Alert Condition" Study (CBBOAC). This study can do so much more than color a bar.

If you want to visualize your alert condition on a chart, this is your go-to-study. I also use this study all the time to construct trigger signals or signal studies which can be used by my SST AutoTrading Study.

Spreadsheet Formula

Another simple but very useful built-in SC study is the "Spreadsheet Formula" Study. This study allows you to calculate your own SG using a formula. Really useful if you want to test your own ideas.

Debug your alerts

The Tool Values window can be used to quickly discover the chart and SG values when you hover over the chart with the crosshair and it's a great feature to debug your alert conditions.
