Example alerts

Actually there are three kinds of alerts. But trading alerts are triggered by trading systems. This post is about indicator-based alerts and price-based alerts. They are both made through "Automate..." > "Price & Indicator Alerts...".
 

Indicator-based Alerts

You can have as many alerting rules as you like. Normally all of them have to be true for an alert to fire, but you can use "Groups" to set up optional alerting rules.

A simple example - send a notification when all of these are true:

• Line 1 is above X, where Line 1 is "ADX", and X = 25
• Line 1 is below X, where Line 1 is "RSI", and X = 30
• Line 1 is above Line 2, where Line 1 is the CLOSE, and Line 2 is SMA(10)
• Line 1 is above Line 2, where Line 1 is SMA(10), and Line 2 is SMA(50)

Put a tick in the "use completed bars only" box.
 

Price-based Alerts

For example, you want to be notified when the EUR/USD price goes above 1.2345:

• Line 1 is above X, where Line 1 is the CLOSE, and X = 1.2345

Remove the tick from the "use completed bars only" box. In this case it doesn't matter what interval you use (5-Minutes, Daily, etc). Because we are using incomplete bars, the CLOSE of all incomplete bars should theoretically be the same. That is, the close of the incomplete 5-Minute bar should be the same as the close of the incomplete Hourly bar.
