The expectancy gap and performance leaks

When trading, you are free to construct your own methodology and set of rules to use - what markets to trade, triggers for entries and exits, how much equity to risk etc. That's the easy part.
 
For the majority of us, the difficult bit is ensuring you keep operating within that framework.

Building your own approach to the markets and the decisions and actions you take are entirely within your own control. But you have no control over what the markets do. Ideally, you want to react to the market's price movements, and trade within the confines of your carefully constructed framework.

How do you define a trend?

The past has happened. The future doesn't exist.

Therefore, we can only react and respond to what is happening in the moment of now.

So, for traders the question is, what is price doing now?

The tricky bit is how you define "what is price doing now".

Trading and the butterfly effect

Have you ever considered how you could come across two or more setups that are seemingly identical, and yet one moves in one particular direction, and another moves in a totally haphazard manner, and possibly start to move in completely the opposite direction?

Mark Douglas gave the best answer to this question in Trading in the Zone. Basically his explanation was as follows:

Trend following and Trading in the Zone

Trading in the Zone, by Mark Douglas, is one of the best books out there on trading psychology, and one I would highly recommend new or inexperienced traders should read.

Reading it confirms that trading psychology is just as important (if not more important) than having a following a particular trading system or method. He states that it is the ability to follow your system that separates successful traders from the rest.
