[amibroker] Manual markers for charts --code included and a question

[Dennis Brown <see3d@xxxxxxxxxxx>]

Hello,

I wanted to be able to enter trades manually --representing the ideal  
discretionary system trades for comparing different automated systems  
trying to mimic them.  I combined several different ideas I found  
here to make the code below.

To operate, you select a name, make an empty ticker, then enable  
manual trades, select a bar and place a marker on it.

It remembers the markers and can display them on any chart.  The same  
idea could be used to mark universal things on a chart such as  
options expirations, fed announcements, 9-11, other market moving  
news that would affect all charts in back testing.  It could also be  
modified to switch files 1-1 for each current ticker for ticker  
specific events.  The advantage is that the data is retained across  
different panes etc. --unlike drawn studies which can not be shared,  
cut, pasted, and could easily be lost.

So far, I have noticed a couple anomalies in operation that I can't  
explain.
The first time I enter a marker after starting AB, it seems to  
disappear after a bit and has to be reentered once.
It lost my markers once, and I am not sure why that happened --the  
files were still there.
Also, I wanted to have a way to make it hard to clear all the markers  
by mistake.  I was looking for a way to require the shift key down  
when clicking on the make empty ticker button as a fail safe.  Or  
perhaps there is a way to make a confirmation dialog box.

I would appreciate any help with these issues and comments for  
improvements.

You make take the following code and use it or post it however you  
like as far as I am concerned.
