scanning multiple chartlists
If I were to scan multiple chart-lists, would the following be the best way to write it :
[[Chart List A] or [Chart List B] or [Chart List C] or [Chart List D]]
Will this miss any symbol in above chart Lists ? Or is there a better way to accomplish the same but more accurately ? Thanks
When you write the scan, select each list from the Chartlists drop down. Then cut an paste and edit them into the syntax you have above.
It won't miss any symbols in your lists that fit your conditions. You can verify this by reviewing all your charts using a chart style that includes the indicator(s) in the scan. Scan results display automatically in your default chart style, but you can apply any other chart style for reviewing the results once you save the results to a list.
Also, it may be that if a symbol already meets the alert condition before the alert starts to run then the alert will not be triggered (I'm assuming an alert triggers when a condition BECOMES true, and not if it is already true - I don't know if that's the case, but it makes sense to me).
If you run a scan (as opposed to an alert) after hours when the data is stable, and the scan misses something you think it should pick up, double check that your chart's indicator parameters (and time frame) match your scan parameters, and that your scan really says what you think it says (including the run date) and if you still are convinced the scan is not picking up something, report it to Support, with all the details - the scan and screen shots of the missed symbols from as close to the scan time as you can. Note that the after hours data is not "stable" until the last update of the day, which is about 6 pm Eastern (assuming you are looking at US markets).
You could be right that the scans are not set up deal with multiple chart list universes. It's worth submitting the question to Support.
[[symbol starts with 'ELY'] or [symbol starts with 'UPS'] or [symbol starts with 'KPTI']]
AND [40 x RSI(5)]
I don't know if it makes a difference. I run alerts on multiple lists as well. I have some that are looking for Weekly indicator changes and some looking at daily. I set the daily's to run at market close. The Weekly's to run at market open.
Like I said, I don't know if it makes a difference. They were in the system changing up some settings so they might have inadvertently knocked something in there out of kilter.
The likely explanation is there were real-time data update problems on the scan/alert database that are/were not apparent on the chart database. It's not the scan logic because it works when the data is there. It's possible the alert design does not anticipate looking it multiple lists, and handles it in some funny way, but that seems less likely.
