As a brand spanking new, full time position trader (finishing my fourth week) my edge is: preserving my initial capital knowing how much risk I am taking ($ and %) understanding what my risk really is what my objectives are following my written trading plan written business plan (almost finished) patience realizing being out of a market IS a position knowing I'm in for the long haul daily journal making mistakes (so far small ones) and learning from them assuming I am wrong and waiting to be proven right, instead of the other way around double and triple checking my orders (think I'm a closet dyslexic) before sending 'em in being able to put my losses behind me keeping a sense of humor knowing there is no spoon and it's all a game and having a fully supportive wife and family (they all love Cocoa)
My biggest edge is having a fully supportive wife. Both emotionally and financially. She has been a tower of strength during this long, long learning curve. I couldn't be doing this without her.
