I’ve heard from many traders that they often take decisions based on instincts. Actually, all non-quants use intuition in some form or another. If you are not using a program that takes all signals that your system produces, how do you decide between several equally good looking trading setups with similar risk to reward? Do you take them all or do you concentrate on only a few? The odds are that you are doing the latter and your ultimate choice for capital allocation is subconscious.
Even though we are defined by our decisions, we are often completely unaware of what’s happening inside our heads during the decision-making process.
Feelings are often an accurate shortcut, a concise expression of decades’ worth of experience.
The process of thinking requires feeling, for feelings are what let us understand all the information that we can’t directly comprehend. Reason without emotion is impotent. (more…)
Seeing an opportunity and acting upon it are two different things.
Over the years I’ve been fortunate enough to get to know thousands of market participants. Some are long-term investors others are scalping pennies per trade on thousands of shares while others manage millions of other people’s money. The interesting theme I picked up on with nearly every one of them is that they each experienced panic and uncertainty at certain times in the market. Oftentimes, this panic stems from the inability to make sense of the market, to gain control of market participation. Thoughts such as whether or not too much capital is at work or perhaps not enough or even whether or not to be in the market at all seemed to consume them.
You are watching a stock that has all the signals you look for in an opportunity. The proper point to enter comes, but you wait. You second guess the opportunity and don’t buy the stock. Or, you bid for the stock at a price that is not likely to get filled if the opportunity does pan out the way you anticipate it will. As a result, you get left behind while the market pushes the stock higher. A short while after the initial entry signal, when the stock has made a decent gain, you decide to finally enter the trade. After all, the market has proven your analysis correct, so you must be smart, and right! Not long after you enter, the stock turns south and you end up with a losing trade. If only you had bought when you first thought about it.
The objective of the trend follower is to employ discipline to offset biases in order to extract signals from prices to the exclusion of other information. In fact, this has greater similarity to a statistical or engineering problem than to a finance problem. Because prices are surrounded by or filled with noise, trend following is a form of price smoothing. You eliminate the noise to obtain a clearer signal. It also can be thought of as a filtering problem. You throw out the excess information that may be associated with trades that are not driving the trend signal.
This is an absolutely
