Currently swing-trading FTSE cash with D4Free. Learnt by painful experience not to keep overnight short on tuesday due to ex-dividend recalculation. Wanting now to trade DAX, DOW and NASDAQ all in cash with the same company. Does the same thing happen with these indexes? Are there any little technical bits and bobs i should be aware of before i learn by painful experience? If i am on the wrong forum which one should i post on?
