Vertigo, There is a beautiful quote that I love about life, and I relate to the market as well. i.e Life unfolds itself to us in small moments. And it is only in those moments, that we are a given a choice to act, which has an impact on the course of our life, or on our trading P&L.
Any decision (good, bad, positive or negative) that we take in the present moment, will have consequences, which we have to live with. What we have thought, felt, analyzed, theorized etc. before does not matter - but just what we do when we have a choice. Trading, in essence, is about what action you take in the moment that is presented to you. And the beauty of this and of life, is that these moments once gone, will never comeback.... its as some wise man said before : You cannot stand in the same river twice.
Cheers.
