I spent many years developing a system but after many years I realized that it takes more then a system to be successful.
Now, my philosophy is a different approach
1.) First, viewing the market on a Macroeconomic level to determine my long term trend of the market UP or DOWN, 6 months to 2 years out
2.) Look at the Socioeconomic view point to determine if we are in a general accumulation, distribution or trending phase (3 to 12 week phase)
3.) Use Technicals to enter, re-enter or exit positions
4.) Fully understanding options and how they can be used to protect and maximize profits
5.) Though I would say that the most important part is understanding how to Lose.
Currently:
1.) DOWN
2.) Nearing a first leg distribution
3.) Everyone can tell you we are overbought but still awaiting that signal that confrms down.. Though you have to have full protection in at this point.
4.) Fully protected
5.) I got a few body punches on this last rally over the last couple days but feel good overall
If you find a system that works for you thats great but its not necessary if you understand how to get thru those 5 areas and as the other poster said... having it stolen is the least of your worries,.
Good Luck
