Put a Param in Period and you'll see what happens
Louis ... Sometimes I am getting both lines but in most of the times not ... If
that's the problem. I just tested the code and did not get the second Plot. When
looking to the code it's array dependent. So the above result is normal for
me ...
Regards, Ton.

Here is the complete code so anyone can test it: Period = 30;
LowestClose= Ref (LLV(C,
Period),-5);
RSIatLowestClose =ValueWhen(C == LowestClose,
RSI(15));
CurCloseToPastClose = C /
LowestClose;
CurRSI_To_RSIatLowestClose = RSI(15) /
RSIatLowestClose;
Plot(Curclosetopastclose, "\n"
+Curclosetopastclose+ " - curclosetopastclose",
colorBlue);
Plot(CurRSI_To_RSIatLowestClose, "\n"
+CurRSI_To_RSIatLowestClose+ " - CurRSI_To_RSIatLowestClose",
colorRed);Louis

Euh...
sorry. I meant EMPTY, not zero. It seems like it does not return
a numeric value. Louis

Hi, I tried this: Instead of
LowestClose= LLV(C, Period) I wrote LowestClose= Ref
(LLV(C, Period),-5); but for some reason about one third of the
time the value of CurMFI_To_MFIatLowe stClose is zero and I can't draw
any line. Do you get the same results?
Thanks,
Louis

A last question: Would it be possible to get a past peak
that is not the exact LLV of today? Because today or yesterday
might be the LLV of the last 20 days. I'd like to set somehow a
buffer zone; e.g. I want to look for the LLV that is NOT in the last 5
days (it would exclude today, or yesterday and the days before).
That may be very useful. How would one do that? I tried
this: LowestClose= LLV(C, Period) AND NOT Ref (C,-1) AND NOT Ref
(C,-2) AND NOT Ref (C,-3) AND NOT Ref (C,-4); but it is a
failure... Thanks again! Louis
Thanks, it works well!

Ah, yes, the following line should be changed: RSIatLowestClose
=
ValueWhen(C == LowestClose, RSI(15));

[amibroker] Easy question again Thanks, I added the
two following plot to the formula: Period =
20; LowestClose= LLV(C, Period); RSIatLowestClose =
ValueWhen(LowestClo se, RSI(15));
CurCloseToPastClose = C
/ LowestClose;
CurRSI_To_RSIatLowestClose = RSI(15) /
RSIatLowestClose;
Plot(Curclosetopastclose, "\n"
+Curclosetopastclose+ " -
curclosetopastclose",
colorBlue);
Plot(CurRSI_To_RSIatLowestClose, "\n"
+CurRSI_To_RSIatLowestClose+ "
-
CurRSI_To_RSIatLowestClose",
colorRed);
Unfortunately the red line is always
1. I must have done
something
wrong...
Thanks,

I guess it is
possible to get the price, simply by
writting
ValueWhen(LowestClose, Close); right?
Yes,
correct. You can also even get any other value.
There is an
additional optional parameter that allows to get the value of
the
last n-th recent occurrence.
Example: ValueWhen(LowestClose,
Close, 2);

Thanks a lot! That was
what I was looking for.

price, simply by writting
ValueWhen(LowestClose, Close);
right?
BTW, when and how do you use your
CurCloseToPastClose... Seems really
interesting as a
concept.

Hello,
You
can do this with the following code:
Period =
20;
LowestClose= LLV(C, Period);
RSIatLowestClose =
ValueWhen(LowestClose, RSI());
CurCloseToPastClose = C /
LowestClose;
CurRSI_To_RSIatLowestClose = RSI() /
RSIatLowestClose;

[amibroker] Easy question again
Hi,
Another easy
question here. (I'm still juggling with the difficult
things
and thanks again to the people who helped me; but why not
add this little
twist while I'm here).
I'd like to use to
know how to use valuewhen to make it possible to know
what was
the price at a particular time.
I had a look in the manual to
many files which unfortunately had zigzag
functions in
them. This is not what I'm looking for.
What I'd
like to do is to compare the price right now to the LLV C of
the
last X periods and to get the value of RSI of that LLV
C at that time to
compare it with the RSI right
now.
Is this possible, without Zig
function?
Thanks,
Louis
