I am building an indicator with discrete values (so that Buffer[i] could be defined and Buffer2[i] could not, but not in every iteration). To let them assume continue values I tell compiler to fill Buffer[i], when not defined, with Buffer[i-1]. My problem is that sometimes Buffer[i-1] is also undefined and then MetaEditor fills it with random value (e.g. 2848596949.293438). My question is, how tell the compiler "if Buffer[i-1] is a random filled number put 0 (or another value)"?
I hope to have been clear!
