Steve,
I had no problem with the attachment. You might look at the options of
your email program under TOOLS/OPTIONS/ATTACHMENTS, and make sure it is
set to "MIME". I'm no expert, but it does appear that your
program is set to BINHEX.
It would be worth a try.

Is there any other method that you can use to share the code in these
indicators? As you see below they are scrambled quite well. I
know they are encoded but why is it necessary to encode them? They
are only text files.

Attached are two AFL Indicators that I've been
experimenting with that
some of you may find of interest. They are intended for those of us
who
are dabbling with AFL code and exploring its possibilities.
My aim was to explore the 'Correlation' function and what I could use it
for. This code, draws an indicator that compares stock data with an
index (or other data). It attempts to identify if the stock
price
trends have any similarity with, or opposite movement to, that index (or
other data).
So the closer the indicator is to +100% the closer the synchronicity of
the data - ie similar tendency/trend. Conversely, the closer to
-100%
the indicator the more dissimilar the data - ie the two data sources
tend to move in opposite directions to each other. I have found it
useful in spotting divergences.
Of course, this is not a new idea and there must be many texts already
written on this kind of indicator. There is also its clear
relationship
with the Relative Strength Indicator in its comparison with an
index.
An explanation of each line of code follows for novices, I hope its
helpful and apologise in advance if it's too simplistic :-)
====================================================
periods = 50 ;
/* 'Periods' are the number of days/ticks/bars chosen. The
'periods'
variable has been used so that it can easily be adjusted without having
to change other lines of code further down. The number can be
changed
to suit the user - lower is more sensitive, higher is smoother.
'Periods' holds this value for later use. */
index = foreign( "UKX2", "close" ) ;
/* The 'Index' variable will hold the close value of the index
(UKX2 in
UK - change these letters to whatever your index ticker code is for your
country). The 'foreign' function searches for the close value of
the
index and it is placed in 'index' for later use. */
graph0 = 100 * correlation( close, index, periods ) ;
/* 'graph0' is also a variable that will hold the result of the
formula
after the equals sign. Additionally, whatever is held in 'graph0'
will
be plotted on the graph. The Correlation function compares the
selected
stocks 'close' price with the 'index' close value over the number of
'periods' originally chosen by the user. This calculation will
produce
a value between -1 and +1 and is multiplied by 100 to turn it into a
percentage for the graph. */
title = name() + " Correlation Index (" + writeval( periods,
1.0 ) + ")"
+ writeval( graph0 ) + "%" ;
/* The 'title' variable will hold, and display on the graph, the
name/ticker of the selected stock, PLUS the text placed in quotes, PLUS
the value of 'periods' placed in parentheses, PLUS the current value of
the 'graph0' variable, PLUS a percentage sign - because the correlation
value was multiplied by 100.
