Not much in the way of heavy supply until 102.25 and above according to my Prime Brokerage contacts. Now that 101.55 has been overcome, we should expect dips towards the intraday lows at 101.20 to be well supported.
Edit: Also hearing of decent-sized expiries later today at 102.00 and 102.25 which might well act like a magnet.
GBP/JPY also keeps on rattling along and I suspect that much of the Yen selling is coming from this direction
