Apart from the GBP that managed to close the week with a small profit, the winner of the week was the JPY. Mr Kuroda from the BOJ decided not to take any action and this strengthened the JPY by 242 pips (always according to my statistic tool).
Only two pairs made significant moves. The Eur/Jpy and the Gbp/Jpy that closed with losses of 275 and 288 pips respectively. The Gbp/Jpy was trading 400 pips lower but after the sad event it started moving higher to finally close just below 150.
Apart from the UK referendum another important even will take place this week. Mrs Yellen will testify before the House Financial Services Committee on Tuesday and Wednesday and could also give a push to the dollar pairs.
I will not recommend any trades this week. It is extremely dangerous to get caught on the wrong side of the market with zero liquidity (ie unknown spread size). If you absolutely want to trade, try the Eur/Usd, Aud/Usd, Usd/Cad and Eur/Aud that could remain in a range and offer trading opportunities from lower time frames. Aim for a profit of 20-30 pips (with respective stop loss) and close the trades before the referendum.
