[amibroker] Re: Does Amibroker always loop through the array?

Thanks Graham. Unfortunately, I tried ref(x,-p) and it produced the 
same result, i.e. the software kept going down the array and would 
stop until filter condition becomes false. With regard to valuewhen
(), I couldn't figure out the correct expression for specifying 
individual elements in an array instead of the whole array. Any 
ideas on what am I missing here?
