This from a spreadsheet I made using the weekly COT (Commitment of traders) report found here - http://www.cftc.gov/MarketReports/CommitmentsofTraders/index.htm. I use this to add some weight behind the trades I make. COT report shows where the big money traders are putting their bets in the futures market and some of the data is quite revealing, especially when it contradicts the retail sentiment.
Look what has been happening with the Yen this past week; it caught my eye. I know a lot of people are watching USDJPY, as am I. According to the COT a lot of money has been shorting Yen futures, a change of 17,482 contracts from the week prior. One contract is 12,500,000 Yen, so that would be 2.18525 e11 yen. Is that right??? With the rate at 114.78 that's about $1,903,859,557 or 1.9 Bill...Pretty cool. Looking at the chart, if you want in now's the time cause there is a nice pullback. Just don't follow the crowd and short it. According to FXCM the retail side is net short, go figure. Remember, short yen futures means long USDJPY.
