Mike's suggestion is fine. However, he failed to point out two
significant programming errors which you made.
for Try 1: Filter = RSI(14) > 30 AND RSI(14) > HHV(RSI(14),1);,
RSI(14) > HHV(RSI(14),1) can never be true because HHV() includes value
of present bar.
for Try 2: Filter = RSI(14) > 30 AND RSI(14) > (RSI(14),1);,
RSI(14) > (RSI(14),1) is meaningless (and in editor's syntax check
should have caught it).
You probably meant RSI(14) > Ref(RSI(14),1)
I'm guessing that either try1 or 2 would work, if coded error free,
though much less efficient than Mike's suggestion.

Note that it is better to store the result of a function call and
reuse it, rather than repeatedly executing the same function call over
and over again. Try something like:
RSI14 = RSI(14);
Filter = RSI14 > 30 AND RSI14 > Ref(RSI14, -1);
