There is a lot of debate as to whether the market is random or not. I started this on a new thread so it doesn't get buried in the old one. The following few posts will offer you a proof. Whether you accept it or not is up to you. I used the =randbetween(-1,1) in excel to generate a random number that could either be -1, 0, or +1 and added that number to the previous quote, starting with an arbitrary number of 1500. The next tick of the market is slightly more complicated than a flip of a coin because you can have a flat tick so there is a 1/3 chance of any one output. The attached chart is what the output looks like. If you don't think that looks like the stock market then you are just blind.
