I brought CFD shares at Vestas wind systems in a sell mode. The opening price was 1328 something and next day the price of one share dropped to 278 approx due to stock split. So according to leveraged CFD product, I should be paid difference in price. But IG broker closed my position and opened new position at new price. This might happen for underlying shares but why its happening to CFD when I am leveraging it and dont own underlying asset? Also, price difference is between buyer and seller right?
