(H+L+C)/3 higher than their previous hlc3 for a period of 3 minutes

[Rd2538]

I'm building my own scanner and in the last filter I'm trying to show only equities with their (H+L+C)/3 higher than their previous hlc3 for a period of 3 minutes. I am using this code: "hlc3 is greater than or equal to hlc3 from -1 bars ago"
But nothing happens,

You'll want to make sure that your scan is running on either the 1 minute or 3 minute aggregation.
"-1" bars ago is a future bar.
your code should look like (for the one-minute aggregation):
hlc3 >= hlc3[3]
and for the three minute aggregation:
hlc3 >= hlc[1]
remember that secondary aggregations are not available in scans. (you can't set hlc3(period=aggregation.minute) and have the scanner run)
