Hi Neil
There is a simple alert system where you don't need to have a worksheet, but you do need to have at least one study on the chart - anything will do. Here's what to do:
1. Click on Analysis/Studies.
2. If you don't have a study on the chart, add one - say Moving Average or Volume, by selecting the study name from the list and clicking on Add.
3. Click on Settings, then type the alert you want in the Alert Condition box, e.g.
c < 9800
will fire if the close price on the last bar in the chart is less than 9800, or e.g.
l < 9780 or h > 9840
will fire if the low on the last bar is less than 9780 or the high is greater than 9840 (I use this type).
These alerts will go off repeatedly if the price moves away from the alert condition and then back. You can do quite a bit more than this without having to resort to the worksheets, e.g. you can check for price crossing over say a moving average study, and you can refer to values [n] bars back. Have a look at the Help file in the section Chart Studies, Study Alerts and Scanning, and go to the final section Alert Conditions and Scanning.
I know the Sierra help manual is very difficult to read - IMO it's not really a help manual at all but a terse reference guide for people who already know what they are doing - but I think if you read it enough times it will start to sink in!
The procedure for setting and changing the alerts is a bit clunky too (compared say to QuoteTracker which is just excellent in this respect), but try using the keyboard shortcuts - it's much faster and easier when you get used to it:
F6 Alt-E A
Good luck!
