To begin with let's just explore the world as we all see it. We have 3 dimensions of space and one of time. I consider this limitation to be a bit naive and somewhat out dated. Money equals life without it we may as well be dead, or could be close to it.
Lets then look at money and its movement I have looked closely at this and now consider money to be our 5th dimension. Being a dimension, I consider it to have boundaries as opposed to being infinite.It need something to wave or travel in, apart from your wallet or bank account. Money is represented by numbers of course and the movement of money in the market always takes the shortest path between two points.As it does so it captures your trades to give it momentum on its pre-determined course. Although it may not appear to move that way, it often appears to take a random course but this is just an illusion, you can't believe everything you see even when you have no doubts.
All the other dimensions are measurable and tangible except time which is relative and a dimension created by man to allow thing to be easily co-ordinated with his fellow man, as well as the other obvious advantages of having a universal and timely world.
When you consider how much we all rely on money, then think of the extreme thing we do to get or accumulate it, you should understand what I mean.
Any futures index is therefor the best predictor of the future for it's underlying market. However to predict the future of the futures market is an entirely different game,it is truly a global game that is well worth knowing.
