Hi,
Forget it . I had not tested over enough time periods. Doesn't look so good
to me now. Back to the drawing board.

Subject: [amibroker] StoRSI + 144MA + BB
rank
Hi,
I was trying to workout a system in Amibroker that would use StoRSI
and 144 Ma for trading rules.
I wasn't having great results until I added a ranking method
presented by Gary Serkoshian in his slideshow presentation. It used
BollingerBands to score and rank the trades.
The following Amibroker Code is what I came up with.
Try it and tell me what you think about the system if you care to comment
and get the time. This is intended for trading a portfolio of two or
more stocks and won't improve the score of only one stock.
// Stochastic - RSI , recommended by Steve
Karnish //
// With portfolio mode //
/*****
** REGULAR PORTFOLIO mode
** This sample optimization
** finds what is optimum number of positions open simultaneously
**

I'd be interested to know how this ranking method
compares with the Relative Strength ones we talked about
recently.
