i decide if i want to take my profit or if i stay in the trade and try to stand the pain till its coming back again into the +.
usdjpy on the 3hour and daily looks to me like a short in the medium term. the usd cannot stay that strong forever.
than i have to take a loss or open a hedge if its possible for the pair and wait. when the pain gets too strong i take a loss. if its 100 or 150 pips its hard, but most of the time i come out ahead.
