I would say there are plenty of people who know far more about the market than I do. I don't profess to be better than anyone, I only do what I know works for me. I get it wrong but not very often thankfully and I only get involved when the price is incorrect according to my personal view of the market. Obviously I enjoy posting lay or back (or trading) advice on here when I have the time but there simply isn't enough time in the day for me to post every day. It takes me about 1-1.5 hours of study per race before I feel I can sensibly advise fellow forumites to risk their cash. At other times I can just look at a market and know instantly when the prices are wrong. Again, I must stress that the prices are only wrong in my opinion based on my methods. These methods have proved correct often enough to tell me I can do it.
I will write a post on Markets, handicapping etc to try and help others understand why I do what I do and how it works; without passing on the Goose that lays the golden egg so to speak

PS. lesblakeman is quite correct when he mentions lemmings at the course/shops. If you read many of my posts where I have advised a lay I also mention lemmings to the slaughter! There are plenty of them!!
