Yep the key is market direction. You don't put RR willy-nilly. This is not a trade to be put on every month on and off. You use your market reading as a guide, if you do you have a chance to learn on mistakes. I also look at existing positions (or planned ones) to see how RR cooperates with them.
Flipping the trade is not the same as locking in loss - unless you take trade off completely. Locking in loss happens mostly in trader's mind.
