Returns True if the alerts have been turned on in Formatting Studies > Alerts. True/False is returned on the last bar only.
For the bars other than the last False is always returned.
Usage
CheckAlertNotes
- There is a difference between AlertEnabled and CheckAlert. AlertEnabled checks the status on all the bars while CheckAlert does so for the last bar only.
- Alerts are only generated for the last bar.
Example
The example below shows how CheckAlert can help eliminate redundant calculations on historic bars as well as in cases when alerts are not turned on:
If CheckAlert Then Begin
If Volume >= 2 * Average(Volume, 10) Then Alert ("Volume is going up");
End;
