Excerpt from Follow your System, The Business One Irwin Guide to Trading Systems:

You can consider a trading system like a small business.  ....  Compare that to futures trading.  Except perhaps for the emotional stress, trading is a very nice business to be in.  You will need a relatively small investment.  You won't need a fancy establishment office.  You won't need to advertise.  You won't need to worry about employee problems.  You won' t have any inventory.  The hours are good.  You can reside anywhere in the world.  You won't have to live or die by the competence of others.  If your trading system is successful, you will have a high-return, easy-to-run business that can support you indefinitely.
