Great Thread. Nothing is Random, randomization is of course impossible as every action has a predetermined consequence. Whether the human mind or tools which the human mind has created have the processing ability to discover the results of all actions before they occur is of course unlikely at our current technological stage.
But having said that the Financial Markets are not as complex as say human life, therefor we are likely to be able to determine fairly accurate predictions of financial markets with the right input data, what of course makes these predictions less stable are variables which we do not have access to, such as other peoples influence. But again this is not random, we just don't have all the data we need.
It is by no means certain that actions have predetermined consequences, in fact it seems it's just not the case. If your right though, we had better stop wasting our time trying to build quantum computers.
Find me a theory that explains how a random activity works. For something to be random it has to happen for no reason, with nothing preceeding it. We cannot as humans beings necessarily predict the consequences of actions, but how can something happen without cause or reason?
Did I randomly come across this post and decide to start writing a response.... well if I was telling someone else about it I would probably say I came across the post randomly - however I didn't, all the events from my birth onwards led me to that point (and of course my mother and fathers actions would of also had an affect, and theirs and so on). So it wasn't random, several trillion variables which all had a set value due to other trillions of variables and so on created the unique event of me replying to this post.
But hey, its just theory of mine - I may be wrong .
