I misunderstood/misread your question. I wrongly assumed it was concerning
an exploration.
Looking at your example below, you are using a price "HHV(HIGH,40)" as if it
were a binary value (true or false). Any price above $1 will be treated as a
binary true. You need to set up a true/false condition inside the
LowestSince() possibly "LowestSince(1,H>Ref(HHV(HIGH,40),-1),LOW)". I'm
assuming the prices you are working with are nearly always greater than $1.
Sorry for the earlier misinformation. Hope this puts you on the right track

I get a plot line identical to the Low of each day (i.e., I get today's low
today, yesterday's low for yesterday, etc.)

when the stock price (High) rises and subsequently falls over a period of
time, AND the resulting High is below my calculated H1, then LowestSince()
calculates the wrong Low. I also tried H1<HIGH, and even H1>HIGH, and
combinations. None work.
