Machiavelli:
I have Reversal Magic, together with Balance Magic and Channel Surfing.
The manuals are comprehensive - the pages aren't numbered so I don't know how many there are, but the three manuals combined are just over 2cm thick. There has been an awful lot of effort put into the manuals, and there are lots of examples, etc.
If I have one moan it is that right the way throughout the author, Michael Parsons, uses the words Reversal Magic a lot. And not only that, but he puts it in capitals, bold, and italics - and it just makes the whole content harder to read. He has obviously forgotten that by the time you are reading the manual, you have paid for it, and therefore you don't need to have REVERSAL MAGIC hitting you in the face seven times on each page. It would be so much better if he just used RM in an ordinary font.
I can't tell you whether you'll find it worth its money - I paid, and in return got to know a natural phenomenon of the markets which I didn't know before, and so I was happy. I've never seen it referred to on these boards before.
Reversal Magic is all about drawing a few lines on your chart to give you reversal points. It depends on how good you are at trading and what methods you use, but I doubt that one would be able to trade solely on these points. But they are quite interesting to know about, and knowing about the projected reversal points gives you more of an idea of the market's natural wave movements.
Most of the examples are on daily charts, and therefore there is often a good deal of time before the reversal point, whereas I trade intraday, and so as I do not trade the entire trend, just each swing within it, I am not that bothered with the timing of reversal points of the main trend.
I don't use them much in my trading (and my style is price and volume only), but sometimes if the market is a bit boring I put the lines on just for my own amusement and they are quite spooky. I use other things to read the reversal points, but that is just because I've progressed quite a lot since I bought Reversal Magic just over two years ago.
Michael Parsons is an educated sort of chap, and so his writing style is easy to read, with good grammar and no spelling mistakes - which is quite a novelty in trading manuals! He also doesn't promote himself heavily, which I've always found quite refreshing - there are some whose sole objective is to promote themselves, and Michael appears not to be one of them.
Getting to grips with the whole Reversal Magic phenomenon will take a few weeks - it'll take a good week to read the manuals in the first place. So for the money, you'll get your money's worth in manuals, etc, and from then on it's up to you how and if you use it in your trading. The basic principle is easy to grasp, but there are things you need to do to account for gaps, holidays, etc, so it's not quite as straightforward as it first appears.
If you're the type who uses lots of Bollinger Bands and moving averages on their charts, then you probably won't find the space to put the Reversal Magic lines on - you need a nice clean uncluttered chart to do that.
Let me know if you need any further information.
