I hope I'm not missing something obvious. But I have a scan setup with one condition group that scans only within a watchlist of positions I want to enter. The custom scan code looks for changes in MACD and W% and is set to DAY aggregation. I have also included "declare once_per_bar;" in the code, but I do not know if that affects scanning routines. I keep getting alerts for this scan with the same positions being added in and then removed. Over and over. There does not seem to be a set interval, sometimes as often as every 3-4 minutes, other times hours can go by. But it is just toggling back and forth alerting that the same group is added and then removed from the scan.
Why if it is set to DAY aggregation would the results change, during trading hours AND after hours, so many times back and forth like this?
Here is a sample of the alerts:
