The day before some corporate actions will take place (ex-date) open orders on CFDs on the underlying securities will be deleted. These are generally liquidation, merges, stock splits, reverse stock splits and spin off. For distributions and right issues (such as capital gain distribution, cash dividends, dividend options/reinvest, right issues, share premiums, stock dividends), all open orders on the underlying instrument will be deleted, if the variation in the market price is calculated as being above 20% compared to the current price as an effect of the corporate action event.
