No matter price entry. IMHO the problem is to handle your "HUGE" loss.
If your position has gone out of your tolerance you have to make a decision.Firmly. Not much options but this is what u can do:

1. Accept the loss. clear your mind from this poison and start again to analize.
2.Hedge the loss. If your equity is bleeding at least you stop the DD before it becomes a catastophe.

-usdchf has this intrisic trap. Attracted by positive swap many retail take the buy side, but brokers, fund managers and istitutional very often take the sell side.
so, it s a matter on how much you can wait in order to gain from swap vs how fast they can push downside the price.
