Jason, thanks for the input. What happens
when I back up a chart so that June 2 (for instance) is the last day
showing at the right hand end of the chart. Hasn't Amibroker
completely forgotton the future knowledge that it aquired while it was in the
future? In other words, can't I visually backtest going foreward one bar
at a time, and won't this method of looking at Zig be exactly the same as when I
download fresh daily data each day. Ron D

Zig
is great for seeing the past but the future......... you must be very careful.
Here is a good description from TA A-Z...

ZIG ZAG
Overview
The Zig Zag indicator filters out changes in an underlying
plot (e.g., a security's price or another indicator) that are less than a
specified amount. The Zig Zag indicator only shows significant changes.
Interpretation
The Zig Zag indicator is used primarily to help you see
changes by punctuating the most significant reversals.
It is very important to understand that the last "leg"
displayed in a Zig Zag chart can change based on changes in the underlying
plot (e.g., prices). This is the only indicator in this book where a change in
the security's price can change a previous value of the indicator. Since the
Zig Zag indicator can adjust its values based on subsequent changes in the
underlying plot, it has perfect hindsight into what prices have done. Please
don't try to create a trading system based on the Zig Zag indicator--its
hindsight is much better than its foresight!
In addition to identifying significant prices reversals, the
Zig Zag indicator is also useful when doing Elliot Wave counts.
For additional information on the Zig Zag indicator, refer
to Filtered Waves by Arthur Merrill.
Example
The following chart shows the 8% Zig Zag indicator plotted
on top of Mattel's bar chart.
<IMG height=268

This Zig Zag indicator ignores changes in prices that are
less than 8%.
Calculation
The Zig Zag indicator is calculated by placing imaginary
points on the chart when prices reverse by at least the specified amount.
Straight lines are then drawn to connect these imaginary points.

CONDITIONS
Today, I finally spent some time looking at the
ZIG indicator. I have attached some charts that demonstrate Zig's
ability to identify uptrends and downtrends. I am wondering if
anyone has developed AFL code that can be used to scan
for symbols that are in uptrends, as well as another scan for symbols
that are downtrending. I am interested in any and all AA analysis coding
that will help me better understand Zig. I searched the AFL library, but
failed to see anything that looked like it could scan for Zig uptrends. My
very short look at Zig makes me think it may be one of the better
indicators to use for determining when to exit a
position.
Is the sensitivity of Zig adjustable?
If it is, then perhaps one could adjust Zig so it takes you out
of some of the more serious pullbacks. Maybe it can be fine tuned to
match the individual trader's tolerance of pullbacks. I have not yet found the
time to learn anything about optimizing, so I will not be able to
do anything in that area.
BTW, I am very interested in starting, or joining
an Amibroker usergroup here in Dallas, Tx, so please contact me if you live in
the Dallas area and know of an existing group, or are interested in starting
such a group. All help will be appreciated. Ron
