Help Needed for AFL Exploration

[Aman03]

Hello All,

Below is AFL has options to plot white lines 0.2% or 0.3% above/below previous day's High/Low.

I tried put in my best efforts to create the exploration which can extract the stocks crossing these levels. I studied many AFL exploration formulae and searched net. But nothing worked.

The result of the exploration' I have attached it as an image.

Please help me build this exploration.
