I don’t always prepare myself for a reversal (which I really should) and then, when it happens in those cases, it catches me off guard rather than being forearmed with an already in the place exit plan. Part of that problem, too, is when the market gaps open widely in the direction away from my profit target. I need to prepare more for that possibility and simply close out the position. I get into an ‘I think (actually I hope) it will rebound’ thought loop. And we know where that invariably goes. Again, I really need to develop better trading habits and not enter trades half thought out.
Just responding to your question has made me aware of additional interesting facets of this issue of which I was not fully aware of previously.
You need a strategy. A complete one.
