Graham:
Are you (or anyone) aware if there is a limitation on the length of a
single AFL line? I keep thinking that Tomasz answered this, but a quick
search did not reveal anything. A line like
DateNum()==900926 OR DateNum()==910621 .......
Holding 150 or 200 dates would be a very long single code line indeed.

Subject: RE: [amibroker] Getting Some Signals Into AB for plotting
Ken it is quite easy to set up the string in excel from all the cells
DateNum()==900926 OR DateNum()==910621
Column A : Datenum()==
Column B: 900926 etc
Cell C1: =A1&B1
Rest of Column C: =C1&A2&B2
The last cell in column C will have the total string, just have to add
the
bit at the start (Sshort=) and end(;) for AB
Cheers,
Graham

Subject: [amibroker] Getting Some Signals Into AB for plotting
I have an excel file of some signals that I want to get into AB for
plotting
and comparisons to AB code generated signals.
I have data in this format:
9/26/1990 Short
11/2/1990 Cover
11/2/1990 Buy
1/31/1991 Sell
2/11/1991 Buy
6/21/1991 Sell
6/21/1991 Short
7/16/1991 Cover
7/16/1991 Buy
11/25/1991 Sell
11/25/1991 Short
Some fancy Excel footwork on my part allowed me to introduce statements
like
this:
Sshort=IIF(DateNum()==900926,1,0);
Scover=IIF(DateNum()==901102,1,0);
Sbuy=IIF(DateNum()==901102,1,0); Ssell=IIF(DateNum()==910131,1,0);
Sbuy=IIF(DateNum()==910211,1,0); Ssell=IIF(DateNum()==910621,1,0);
Sshort=IIF(DateNum()==910621,1,0);
Scover=IIF(DateNum()==910716,1,0);
Sbuy=IIF(DateNum()==910716,1,0); Ssell=IIF(DateNum()==911125,1,0);
Sshort=IIF(DateNum()==911125,1,0);
I had to get this far to realize that the last Sshort statement would
replace the Sshort array from previous statements, in other words, I am
able
to plot only the LAST signal for each array.
I do not think I want to create a statement in Excel for something like
Sshort=IIF(DateNum()==900926 OR DateNum()==910621 OR ..... etc. It
seems
like I would have to hand type in all dates. Yuk!
Can someone suggest how I would go about getting the data shown at the
top
into four arrays that can have the points highlighted with PlotShapes
statements? I am stuck.
Thanks for any help,
Ken
