paintbar referencing the symbol(tick.z) high, and the tick.z low

[ssyl]

Hi Guys,

I have a chart of NQ, and i want to highlightwith a paintbar when the Tick.z hits >800;  no problem, i have done that, by having tick.z in the lower window (using High of tick.z).  but i also want to flag when tick.z (low) hits < -800.  i can put tick.z (low) in the lower window also, but i don't know how to reference the first tick.z vs the second tick.z in the paintbar logic.

tx.
