I am trying out 4.29.1 and its wonderful new functions that let me
select a from-to range on a price plot. Thanks Tomasz. Great addition.
What I want to do is calculate a standard deviation over the selected
range. While the example for "percentage change" in price that is
included withe download works great, the standard deviation function,
like many others, wants to know the period to be calcated over.
StDev(array, period);
So I am trying to find the period as follows:
Range (or period) = EndValue(Datetime())-BeginValues(DateTime());
however, this expression and the variants of it that I have tried
results in error messages when I try to write the value of StDev in a
Title expression.
I'm sure I messing up formats or something similar and I cannot find
the Help descriptions that will get me out of my dilema.
Long winded, but the basic question is: "How do I find the range
in "bars" for a given From-to range such that I can use it in
functions like StDev?"
Second associated question: "How do I direct the Title function to
execute a carriage return?"
Thanks
Bill
