The condition
Cond=RSI(n)<30;
will be true for some bars.This is your Wait function.
Wait=RSI(n)<30;
If you want to buy at the last <30 bar, then you should use
Buy=Cross(RSI(n),30);
It is equivalent to
Not(Wait) and Ref(Wait,-1).
You can not, of course, know the last <30 bar before the first >30 !!
