Hi,
I had purchased CFD;s on 28th Jan when IG was still allowing trading CFDs for AMC.
Today when the shares prices crashed, I was not willing to let go of my CFDs and i tried lowering the STOP price, but IG did not allow me to change the STOP price quoting that "they are not accepting CFDs for this share". Now i understand your right to change the option for new deals but I had an existing deal.
Due to not being able to change the STOP I lost my CFDs deal and LOST money. Note that I have sufficient money in my account to cover any lower STOP values.
