I always say you could publish rules in a newspaper and no one would follow them. The key is consistency and discipline.
A good trend following system will keep you in the market until there is evidence that the trend has changed. 
I could trade without knowing the name of the market.
Trade small because thats when you are as bad as you are ever going to be. Learn from your mistakes. 
You should always have a worst case point. The only choice should be to get out quicker.
When you have a position, you put it on for a reason, and you've got to keep it until the reason no longer exists.
