So I already send 3 mails to the german customer service, but haven't gotten an offical answer yet, I tried calling but hung up after an hour. This is my mail:
I am interested in trading during the extended hours. I have some questions about order execution.
1. When are the CFD orders forwarded (HFT provider?)? Who takes the opposite position in a CFD trade (CFD Trade in Extended Hours)? What sources do you use to find a counterparty?
2. When can orders in extended hours trading not be executed? Would it be more likely that the order cannot be executed during the earnings announcement / in the case of high volatility / jumps? Could a buy order at $ 460 and a sell order at $ 470 have been executable in today's after-hour trading at Netlix? I attached the chart with purchases / sales every second at the moment of publication of the quarterly figures.
3. Slippage: What tolerance limits has IG set as the default? How can I expand / reduce this? For example: If I want to enter a CFD buy order at 460, can I set a slippage of $ 5?
Would be much appreciated if I could get an official answer from IG
