Sometimes you hope the markets will go up or a stock will do this or that.
Hope is for the unprepared.
If you're trading for a living, you can only control your own actions. So if a stock moves down, where do you plan to limit losses? What signals will indicate the environment has shifted?
When will you switch from offense to defense?
A trader must always be prepared to go over the scenarios and diligently watch for the signs of shift in investor confidence. A trader must always have an actionable game plan that covers every scenario.
If not, the trader will inevitably start hoping -- a sure sign that one's strategy is closer to failure than realized.
