Thanks. It's working now. However when I try to implement CrossBelow() I get a similar error as before, please see:

Any thoughts to fix? Thank you

Hello agclub,

Both values you are trying to use are doubles and not series. Using KAMA1[0] gets a specific value from the series, that is a single number. GetCurrentBid() also returns a single number. To use the Cross methods you need at least 1 series, you could compare the KAMA in reverse with the bid like the following:

if(CrossBelow(KAMA1, GetCurrentBid(), 1))
