close(0) is fine though. As is HighVal(1).
See this public screen.
Aggregate(“HighVal(1)/Lowval(1)”, #All, #Avg) is also NA.
HighVal can’t take 0 as a period parameter. What would that mean? The highest closing price in the last 0 bars? Perhaps you want Hi(0)?
As for HighVal(1)/LowVal(1) that would always be 1, since the highest closing price of the last 1 bars would always be the same as the lowest. And the Aggregate doesn’t return NA, it returns 1, as it should.
I meant Hi(0) and Low(0).
Thank you.
