over the week end markets will be slow because big brothers(banks and central banks) are no trading.
so no point trading when volatility is no there.
oanda still open for week end thats mean you still can open or closed your position but can you bear the higher spread on week end? some pairs 30-40 pips,pairs like eu 10 pips at least.
oanda do open for trade on 1/1/2009 but the spread were simply killing. eu around 15-20 pips.gu 20-40 pips.
