What happened with JPY today?

I am a newbie trader, but normally when I see a move like what happened around 10am, it is for some fundamental reason or other. But I didnt notice a thing on Forexfactory or Forextv or Dailyfx.

Does anyone know what caused this, or did the Bank of Japan just feel like stopping out some traders?

They didnt get me though .

SupaDre.

the bank of jap intervenes and traders will buy breakouts not much more to say
they created bullish outside wave on the daily which will retrace a bit when they think theyve created enough room. and it will be bought back

Wow! Thanks, domino.

I guess this is something I have to look out for. But I would have faith in the major up trend, and place my stops far from those spikes in the future. Right now, there is no chance of me being stopped out but I am still in the red.

There was a Japanese holiday and while japan partied others took advantage of the low volume to create a nice down move, nothing more.

during holiday periods you'll often see big moves on low volume!!

There was quite a difference between brokers. FXDD's had 2 spikes including a whopping 60 pipper on the 15 min and FXCM didn't.
