Please help to prepare EXPERTS ADVISOR for
Example :
L = 10000
REF(L,-1) = 10020
REF(L,-2) = 10019
REF(L,-3) = 10018
,
,
,
REF(L,-(n-1)) = 10002
REF(L,-n) = 10001
REF(L,-(n+1)) = 10002
REF(L,-(n+2)) = 10003
Please advise how can I express
when “L” drop below Ref(L, -n)
i.e. the nearest lowest value,
of which “n” to be the bar counting back from “L”.
Thanks in Advance.

How about something like:
a1:=LLV(L,5);
a2:=Cross(a1,L);
a2

Hi John,
Thanks for the reply.
I tried yours but seemed no indication yet.
We don't know when will the "L" drop below the last lowest.
Can we first locate the last lowest by :
Ref(L,-1)>L and
L<Ref(L,1)
and define "L" be someting, say "X", the current Candlestick will always compare with 10001.
Have you got any suggestion ?
Thanks

Hi,
what do you mean with last L - do you mean the low of the previous day or do you mean the lowest value of the previous n days?
x:=ref(L,-1); {x is the low of previous day}
y:=LLV(ref(L,-1),5); {y is the lowest low of the previous 5 days}
L<x;
L<y;
edit: sorry have forgotten to add the ref -1 at the lowest low function - without the ref the actual low would be included

Hi Vienna and Oztrader,
Thank you for your help.
I don’t know how to post a jpg file here. However, I would like to forward a snap chart showing the nearest lowest “L” for your reference.
If you don’t mind checking out the chart, please forward a short note to my email betycook@gmail.com. So that I can feedback.
Thanks

Hi betycook, now I have an example for you with which you can get something equal like you showed in the chart. You can change the periods slightly to adjust it in a way you like it more.. period1:=10;
period2:=3;
bottomoccured:=LLV(L,period1) AND Ref(Cross(0,LinRegSlope(L,period2)),-(period2-1));
previousbottom:=ValueWhen(1,bottomoccured=1, LLV(L,period1));
belowbottom:=Cross(previousbottom,L);
previousbottom;
belowbottom*LastValue(C);
The "*LastValue(C)" Part is only used to show the bottoms and the Signals in the same chart.
Notice also that there are a lot of different way's to determine the "real" previous low, with their advantages and disadvantages..
cheers

Dear Vienna,
Thank you so much for your effort.
I will test and try to understand the expressions.
However,could you pls let me know how and where I can learn more and strengthen my Metastock language. MetaStockFormulaPrimer does not provide detail and sufficient codes. Pls advise any other sources which may be useful.
Again, thanks a lot.
Cheers
betycook
