Thanks for the reply.
Prior to last week, I could place new orders in to the auctions during the auction periods via your web platform. I could also amend and delete existing orders during the auctions. I have done so for years all via your web platform.
I realise the LSE outage was nothing to do with IG, but it seems that this outage has triggered a change which has restricted the functionality of your platform. I would appreciate it if someone could look into this.
Many thanks.
