Ara said just use the variable. For instance C is an array and using
C will point to the last value, or the current bar, in the array. To
point to a bar prior to the current one use Ref(C, -n); where n is
the number of bars prior to the current one. Replace C with the array
you want to get the value for.
Use LastValue when you need a value and not an array. An example is
in an IF statement. IF() cannot take an array and you have to get the
value. If you want the value of some previous value use LastValue(ref
(c,-n));
If your results get confusing dump it to the interpretation window so
you can compare the values with what you expect them to be. Use
something like this:
printf(numtostr(lastvalue(c), 1.2)); // current value of c
printf("\n" + numtostr(lastvalue(ref(c, -1)), 1.2)); // previous c
