You can start a new position. Only noobs hold their losses too long. Then they get deep in the red they get afraid to take a loss and hope the price comes back up. That's how bag holders are born.
Trust me I've done this like first 2 years when I first started trading. Never fall in love with your trades. Better to stop out out and take a small jab to the chin than hold on til your trade blows up
If you're trading on margin, then yes, I'd agree.
I wanted to edit this and apologize for being combative.
I think the point I was trying to make is that sometimes in a fast moving, volatile market, many times the price will run on you and you won't easily be able to open a new position.
Of course this can work both ways and you can indeed be left holding the bag.
I was simply trying to point out that there is a chance that it is the fiat bag holders that might lose out on this deal.
