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 ...

I meant EMPTY, not zero. It seems like it does not return a numeric value. Louis 2008/7/22 Louis Préfontaine <[EMAIL PROTECTED]>: 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_MFIatLowestClose is zero and I can't draw any line. Do you get the same results? Thanks, Louis 2008/7/21 Louis Préfontaine <[EMAIL PROTECTED]>: 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 2008/7/21 Louis Préfontaine <[EMAIL PROTECTED]>: Thanks, it works well! Louis 2008/7/21 Thomas Z. <[EMAIL PROTECTED]>: Ah, yes, the following line should be changed: RSIatLowestClose = ValueWhen(C == LowestClose, RSI(15)); Thomas www.PatternExplorer.com From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Louis Préfontaine Sent: Monday, July 21, 2008 11:51 PM To: [email protected] Subject: Re: [amibroker] Easy question again Thanks, I added the two following plot to the formula: Period = 20; LowestClose= LLV(C, Period); RSIatLowestClose = ValueWhen(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); Unfortunately the red line is always 1. I must have done something wrong... Thanks, Louis 2008/7/21 Thomas Z. <[EMAIL PROTECTED]>: 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); Thomas www.PatternExplorer.com From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Louis Préfontaine Sent: Monday, July 21, 2008 11:37 PM To: [email protected] Subject: Re: [amibroker] Easy question again Thanks a lot! That was what I was looking for. I guess it is possible to get the price, simply by writting ValueWhen(LowestClose, Close); right? BTW, when and how do you use your CurCloseToPastClose... Seems really interesting as a concept. Louis 2008/7/21 Thomas Z. <[EMAIL PROTECTED]>: 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; Thomas www.PatternExplorer.com From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Louis Préfontaine Sent: Monday, July 21, 2008 11:02 PM To: [email protected] Subject: [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
