Roy:
Thanks for the rapid response.
I think I understand the "periods" suggestion, and will set that up as a separate Indicator to call by Explorations.
But I don't understand your response on LowestSince(), or my question was not phrased well, or both!
I was first trying to use LowestSince () in a chart. It was my understanding, from one of your earlier posts, that Indicators in charts scan ALL loaded data; so minimum should not be an issue as it is in the Explorer.
When I try to chart an Indicator using "LowestSince(1,HHV(HIGH,40),LOW)", 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.)
I then thought that perhaps there had to be some form of cross for LowestSince() to function, so I created an Indicator which used:
H1:=HHV(HIGH,40);
LowestSince(1,H1=HIGH,LOW)
This at least plots a curve, and works correctly part of the time, but 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.
So there is something which I must not understand about how LowestSince() actually functions.
Any wisdom would be greatly appreciated.
