Time-based condition alert

Hello !
I have an alert condition with this code, which looks to see if SG1 is <= to -18 on the 5th previous period. But, I want the alert to trigger if SG1 is, at least once <= to -18 over the last 5 periods.

Can you help me? Thanks !


AND(CROSSFROMBELOW(ID18.SG1, ID18.SG2),MIN (ID18.SG1[-5]) <= -18)

We are confused by the "CROSSFROMBELOW()" that you have in what you posted. That does not make any sense with the test that a value is less than -18.

An alert to test if any of the last 5 items is less than -18 would look like the following:
=OR(ID18.SG1[-5] < -18, ID18.SG1[-4] < -18, ID18.SG1[-3] < -18, ID18.SG1[-2] < -18, ID18.SG1[-1] < -18)

In this case the current bar (ID18.SG1 or ID18.SG1[0] if you prefer) is not being tested, if you want it you would need to add it to the list.
