I have a hard time distinguishing with my readers what they are really trying to accomplish.
Invest or trade. Nobody likes to lose mmoney. Therefore you have to trade or invest to suit your make-up. What can you live with and go to sleep at night without losing sleep if something happens on a bad day.
A bad day, week, month or year will always happen to someone somewhere.
I like to say invest for the long term and wait for the smoke to clear and you will be on the train to profits.
Then you have to protect your profits. So use trailing stops so that you can ride the train as far as you can.
