Yes Dennis, I share your feelings.
I just added one bug report (#1466) Arrows drawn on linked
multiple timeframe charts do not line up horizontally - it
is a bit long (see
http://www.amibroker.com/feedback/view_bug.php?bug_id=1466 )
and one suggestion (#1465) Add property to manually drawn
arrow "hollow"
(http://www.amibroker.com/feedback/view_bug.php?bug_id=1465
)

Subject: [amibroker] Study Charting dare I say bugs...
Friends,
AmiBroker is a wonderful program for many things. In fact I
use only a fraction of its total capability for my trading
style. I trade only single ticker (futures) real time and
write whole trading systems just in AFL in indicator mode.
This is actually more like the traditional chart trading
that is offered by many brokers.
I would expect that AB, which supports all these functions
as a very basic operating mode would be at least as good as
other charting programs.
However, even though the fundamental operations are there
(and I think potentially better), the interface (either
design or implementation bugs --I don't know which) has made
it hard for me to use this product for drawing even basic
lines on the charts while trading. In fact, I need a second
chart from my broker's application open to the same ticker
just so I can draw lines where I want them even though AB
would be superior at this if it were not for the bugs. This
has been going on with me for over a year now and it is
costing me.
I have other trading friends that I have recommended try AB
in the last week, and I am embarrassed to think what they
will say to me when they figure out that these basic
features don't work properly. I have actually refrained
from recommending AB to them for quite a while -- hoping
these things would be fixed first.
I don't know how many other traders are frustrated by the
same bugs, but if you are, please join the conversation so
that Tomasz knows that this is important to you also and
perhaps we can get some higher priority on getting the study
charting to work properly.
Here is a short list of my frustrating bugs --there are
others on the suggestions and bug lists, but I am only
pointing out the ones that cost profits by either making it
very slow to do a simple operation that makes one lose the
trade opportunity, or creates frustration and emotion which
takes one out of the trading "Zone", or makes the line drawn
correctly to become inaccurate causing one to miss the
trigger point for a trade. If I have missed any that you
feel are costing you profits (not the nice to have pretty
things) than please add them to the conversation.
#726. Handles from a selected study line are not respected.
Often several lines are anchored or pass through the same
pivot points.
Price levels, Trend lines, Forks, Fibs, etc., often use a
common pivot point. However, as a trade progresses, new
pivots become more important and the lines need to be
adjusted in real time. It is easy to select a study just by
clicking on it in a spot where it is unique, and the handles
will appear along the line. However, unlike any other
charting program I have ever used, clicking and dragging on
the visible handle will not usually work properly if any
other study crosses very close to that handle. The problem
is that AB will grab the earliest drawn study and not the
selected one --it will un-select the one you selected and
select the oldest one and drag it instead.
After playing around for a few valuable seconds trying to
grab the right line, I end up having to move the whole line
away from its current location and reposition all its
handles. Very frustrating and takes the time and
concentration away from the trading action.
#728. Horizontal price levels do not stay horizontal. The
horizontal lines (price levels) do not snap to a bar with
the magnet mode on.
They just are placed at the cursor level. However, if you
click on the line, it jumps to an angled line that snaps to
the bar on the left side of the screen. Its operation is
just bizarre and causes errors in placement of the price
level after the fact. Completely unacceptable behavior for
trading.
#890. Study handles change when off screen. Let's say you
have the magnet on and are zoomed out and draw a trend line
between two peaks.
Next you zoom in on the trading action so that only the
right hand handle is visible on the chart. Now say the
prices have advanced to a new peak and you need to adjust
the right handle to the new peak (this is a very common
occurrence). Most of the time, that handle that is off
screen jumps to a new bar position and is no longer on the
peak you selected. Of course that changes the slope of the
trend line to the wrong one, but you never know it when
trading and you end up placing bad breakout trades because
the line is in the wrong place now. Completely unacceptable
behavior for trading.
#990. Drag shadow is on the wrong bar. When dragging a
study, there is a thin "shadow" line that shows which bar
you have dragged the handles to. However, when the mouse is
released, the study gets moved to a different bar than the
one indicated by the shadow. This wastes valuable time with
two or three attempts to figure out which wrong bar to put
the shadow on to get the study to go where you want it.
This is an annoyance.
And here is one more that I just found today. If I draw
trend lines on a one minute bar snapped to peaks, then
switch to a 5 minute view, the trend lines are shown on the
wrong 5 minute bars. And heaven help me if I select the
line in that view, because it will snap to these wrong bars.
There you have my short list. Please speak up if these
issues affect you.
Best regards,
Dennis
