Hi all, have called IG twice today, after waiting for half hour each time I was cut off, very poor. Hoping to have better luck getting an answer to my query here... What do IG consider to be a point? If I look at a share that is say 4p and for arguments sake lets say I think it will go to 5p and I want to make £1,000. I am trying to work out whether I bet £1,000 per point or whether it should be £100 per point for example. Does that make sense? It will depend on what IG consider to be 1 point i.e. if they consider it to be 1 full pence or whether they consider it to be 0.1p for example. Hope my query make sense. Any help greatly appreciated
