Hi Trevor,
I have attended nearly all of Peter's seminars 9except the ones in Fiji & hayman island!!) and over the past couple of years have worked a lot of his material into my own investing style. I bought his Foxtrader and have been using it for over a year now.
I don't want to bag the program, as it is good but I have become so used to Metastock (which is the industry leader) that it's very hard to get used to a program that doesn't do things as well. Having said that, Foxtrader attempts to be both a technical analysis tool AND provide company fundamentals so that you can follow Peter's 7 power principals etc.
If you have never used any technical analysis program before, I would say it's ok. It obviously works well if you are going to use his system of options and long-term investing. I'd still go for Metastock though, as it just does it all so well.
Just an opinion though!
