The hardest part of decision-making is being able to split information from noise. Within a textbook-investment problem, you are given useful information which you employ to create a probability distribution of possible profits. You take all the information and find the expected value for an investment and make the decision.

The real problem is when you have too little or too much information. The problem of too much information is one that has always vexed traders but is not often handled within an investment course. Nevertheless, there are simple solutions that have always been used to deal with this problem.

We just may not discuss it in conditions of noise. A large part of the value associated with trend-following is on noise reduction and price smoothing. Take into account the simple case of the moving average. For example, you take twenty days of information and average to compress into one quantity. That is a noise-reduction technique.

All of the fluctuations from highs and lows as well as the daily movement is filtered out through averaging. The sound is cut by us to get the true sign. Most system research is trying to get the right trade-off between noise reduction and information efficiency. If you take too long of the moving average you are throwing out too much information. Employ a short-term moving average and you still have significant noise.

This reduction process might calm decision-making for the better.
