I have a simple system and trading methodology for my Roth IRA. It has nothing to do with daytrading - more like market timing. I have been taking trades that contradicts or ignores my model out of shear stupidity and fear of missing some move. I call this "noise" (albeit the internal kind) My model does not even work well on the short side - so lately I have been experimenting going long gold - in lieu of shorting when signalling a top in the major indices. I have been short the maket twice due to my bias and opinion when I should have just followed my system. I have exited a long S&P position prematurely and to compound the error I went short. The bottom line of this post is - you can buy/invent a great trading system - but if you do not follow it in a disciplined fashion you will just agravate yourself. But I am sure I am saying nothing new here..
