After going thru the 4 different methods you suggested
for drawing lines, I come to the conclusion that
using the drawing tool “horizontal line” would be the
most effective way to implement direct chart trading.
I realize I can draw 3 horizontal lines on the chart
and then modify the properties as needed: color, study ID, etc…
but that is not efficient.
Also since the actual trading parameters would need to
be in AFL it seems only logical to control horizontal lines at code level
also.
So for the $64,000.00 question; Is it possible to create/access/control all of the properties
that make up the “horizontal line” from the draw toolbar and reference them
in AFL code?
Thanks for your reponse.

[amibroker] Question for Tomasz?
Hello,
You can draw your lines using FOUR different methods:
a) PlotGrid - this function allows to plot horizontal
grid line at any leve (the easiest method)
Plot( C, "Price", colorBlack, styleCandle );
PlotGrid( LastValue( Close ), colorRed ); // this example plots horizontal line at the value of last
close
b) Plot - using regular Plot you are able to plot any
line including horizontal lines:
Plot( C, "Price", colorBlack, styleCandle );
Plot( LastValue( C ), "LastClose", colorRed ); // this example plots horizontal line at the value of last
close
c) you can draw trendlines (not only horizonal) using
combination of Plot and LineArray:
Examples here:

d) you can draw ANYTHING you can imagine, using low
level gfx:

Question for Tomasz?
Tomasz,
Are the properties that define the drawing tools
somewhere in an AFL code? In other words I want to be able to
create a horizontal trend line thru AFL code and be
able to control its behavior in my code.
The goal is trading from price chart by creating
horizontal trend lines that would trigger entries, set stops and
targets, with a click of a button I want to place 3 or
more trend lines in price pane and then be able to adjust
there location, once set then arm them and when price
crosses orders are sent out.
I understand that I could use the horizontal trend
line drawing tool to create 3 trend lines then go to properties
and set the study ID of each line. But I want to
automate the process thru AFL.
Thanks for your input.
