Having read and tested the Racing Stock Market system, I would say that it is very unique, and it definitely works! The author claims that the system is secret, but it's mostly common sense once you have read and fully understood the concepts that the system works on.
Inside the Racing Stock Market, you will learn 3 types of betting methods. The first one is mostly a trading method that takes advantage of the SP price. With the SP, you can be much more certain that the odds you will be trading off at are in your favor. The only thing I don't really like about it is that you have to be at your computer screen monitoring the horse before the race starts. But overall, this method has been very profitable giving me small guaranteed profits, so I am more than satisfied with it.
The other 2 methods are based on backing and laying high value horses. Both methods generally work around the same concepts, and over the long run, you will find that you can back horses at far higher odds than other average punters. Likewise, you will be laying horses at far lower odds than other punters. I personally like to trade off the horses I find with these 2 methods because it guarantees me a profit.
But according to the author, because your bets are much more valuable (higher than average back odds and lower than average lay odds), you can still make a profit over the long run if you don't have the time to trade off. I have not tried this method though, and I am very happy to always trade off for a guaranteed profit. It is all up to you though. Racing Stock Market system is really a breakthrough horse profiting system that I highly recommend you to check it out now.
