Subject: [amibroker] Need help
Hi,
I just try to test out an article by Larry
Connors "Do You Buy Breakouts? Think Again" <A
href="">http://biz.yahoo.com/tm/031208/11017_4.html.
However, I have been struggle with the AFL code
to find out the total points as described in the article (I do not expect the
same figure but should be close enough). There are two ways I can do it (I
assume), one is the easier way using AA backtester but I faced the challenge
to fix the number of contract to 1. The number of contract get increase and
decrease along the way and I have played with the Positionsize but no success.
Another way is to accummulate the different between the sellprice and buyprice
and use Explorer to find out the net total points. But I failed to code in
both ways.
Following is the AFL I have tried but
failed. Greatly appreciate your help here to point out my error.<FONT
