<FONT face=Arial color=#0000ff
size=2>Rakesh,
I
found the number of bars that have elapsed since the pivot by calculating the
last valve of barindex() and subtracting the value at the pivot. If you want to
simply know how many total bars have elapsed at the pivot from day one
then use Barindex(), So in the title line use
<FONT face=Arial color=#0000ff
size=2>
Title ="Number of Days
Past "+WriteVal(BarIndex()+1,1.0)+
EncodeColor(colorDarkBlue) + FullName() + " [" + Name() + "]
"
+
WriteVal<FONT color=#282828
size=2>(DateTime<FONT color=#282828
size=2>(),formatDateTime<FONT
face=Arial>) + <FONT color=#ff00ff
size=2>"\n" +<FONT
color=#0000ff size=2>
EncodeColor<FONT
color=#282828 size=2>(colorBrown<FONT
face=Arial>) + <FONT color=#ff00ff
size=2>"WinMidas Support/Resistance"<FONT color=#282828
size=2>;
Of
course you will also need to adjust the MAX value in the parameter line to more
accurately reflect the total number of bars you collect. I am not so sure this
is really what you want though... Consider the lines
<FONT face=Arial color=#0000ff
size=2>
basecumpv = <FONT
color=#0000ff>Ref( Cumpv, -<FONT
size=2>numdays);// numdays
);
basecumvol = <FONT
face=Arial>Ref( Cumvol,
-numdays);//<FONT color=#008000
size=2>numdays) ;
<FONT color=#008000
size=2>
<SPAN
class=769492821-15042004>if you enter the
number of days to the left then you are really asking for the value of cumpv on
day 1 and the value of cumvol on day 1. I am not familiar with winmidas so I
could perhaps be wrong....hopefully the exercise at least showed you the value
of being able to create your own
functions..

Thanks for the code. There is an obvious flaw in it. It is giving the
number of bars to the right of the chosen pivot instead of the bars to the
left as it should- atleast that is my understanding. Rather than ask you to do
the code for me, if it is not inconvenient could you guide me through the
process? I understand it will take time given the various constraints on your
time. However if you can guide me I will better understand how you approach
the problem rather than just enjoy the fruits of your labor.

<FONT face=Arial color=#0000ff
size=2>Here is a first draft that you may find workable. The top 5 lines of
your code are designed to count bars. Rather than going to the trouble of
entering the date instead you may simply click on the bar you with to start
the study from and you will see the number of bars back listed in the title
line of the chart. Take that number and enter it in the
function...
<FONT face=Arial color=#0000ff

<FONT face=Arial color=#0000ff
size=2>example SR(50) will plot your code for the last 50 bars. Since
you are eyeballing the chart it should be easy to find the important data
points. In your plot lines simply add the appropriate numbers I have
not tested the code but simply made a function of the code you posted....

Jayson,
Thanks for the response.
Let me put the problem in perspective. Maybe then you can understand
what I need and tell me if it is possible with my rudimentary programming
skills.
I am working on the MIDAS method.
The support/resistance lines are date specific i.e. launched from
specific dates which are user selected by eye balling the chart.
I had written the code for this in MS which HarveyHP was kind enough
to ammend for use with Amibroker. The code is appended below for your
examination.
MIDAS CODE FOR AB
/*

size=2>"\n"
+EncodeColor<FONT

====================================
Now as you can see it allows for only one launch of a S/R level..
This code needs to be ammended so, that several SR levels can be launched
from differing dates.
I will appreciate your comments on the workability of what I am
trying to do per se and also in context of programming skills necessary
for undertaking this exercise.

function as many times as you wish in as many plot statements as you
need. Here is an example of a function for the tillson indicator that
was discussed at length by Dt a few weeks ago. Note the plot lines at
the end of the code where Ti3 is called using different

Can someone please explain how I should go about plotting
multiple instances of an indicator with differing parameters in the
same chart pane?
In simple words lets say an oscillator of EMAs' of periodicities
3&10, 5&35 etc etc.The paremters are not predefined but are
manually entered.
TIA
