Ok,
I'll try to implement them.

These are the formulas:
MEDIAN PRICE = (HIGH+LOW)/2
AO = SMA(MEDIAN PRICE, 5)-SMA(MEDIAN PRICE, 34)
AC = AO-SMA(AO, 5)

I've tried this in zorro but don't work:

vars median_price = series(MidPrice());
var ao = SMA(median_price,5)-SMA(median_price,34);
var ac = ao-SMA(ao, 5);
