Liquidity is not particularly good in the market today and the EUR/USD has fallen 75 pips on what has been mainly cross flows- EUR/JPY, EUR/CHF and EUR/GBP selling. The problem for the EUR/USD is that there are not many buyers around and hence the quick fall. If no Sovereign bids appear soon then the stops below 1.2735 will be easy pickings and we could be in for an even sharper fall.
Perhaps it might be a good idea to trade in slightly smaller amounts than usual as liquidity decreases and volatility increases.
