Just don't stay long into the week end, at least I wouldn't.
I see its now at 120.86, I took profit too early, as always...
I would short it here with stop above 121.10, but since I hate using s/l I am not going to trade it.
You have G-7 meeting this week end, for now we don't know if "yen weakness" will be one of the main topics, lots of contradicting statements about it. Although yen is and will remaing garbage currency with no value, if they do mention it then sharp down move is possible perhaps even 1000 pips.
This will of course allow big money forex crime ring to load up longs (usd/jpy and similar) and collect interest forever.
